  • Overexpression of Rev1 promotes the development of carcinogen-induced
           intestinal adenomas via accumulation of point mutation and suppression of
           apoptosis proportionally to the Rev1 expression level
    • Authors: Sasatani M; Xi Y, Kajimura J, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Cancer development often involves mutagenic replication of damaged DNA by the error-prone translesion synthesis (TLS) pathway. Aberrant activation of this pathway plays a role in tumorigenesis by promoting genetic mutations. Rev1 controls the function of the TLS pathway, and Rev1 expression levels are associated with DNA damage induced cytotoxicity and mutagenicity. However, it remains unclear whether deregulated Rev1 expression triggers or promotes tumorigenesis <span style="font-style:italic;">in vivo</span>. In this study, we generated a novel Rev1-overexpressing transgenic (Tg) mouse and characterized its susceptibility to tumorigenesis. Using a small intestinal tumor model induced by <span style="font-style:italic;">N</span>-methyl-<span style="font-style:italic;">N</span>-nitrosourea (MNU), we found that transgenic expression of Rev1 accelerated intestinal adenoma development in proportion to the Rev1 expression level; however, overexpression of Rev1 alone did not cause spontaneous development of intestinal adenomas. In <span style="font-style:italic;">Rev1</span> Tg mice, MNU-induced mutagenesis was elevated, whereas apoptosis was suppressed. The effects of hREV1 expression levels on the cytotoxicity and mutagenicity of MNU were confirmed in the human cancer cell line HT1080. These data indicate that dysregulation of cellular Rev1 levels leads to the accumulation of mutations and suppression of cell death, which accelerates the tumorigenic activities of DNA-damaging agents.</span>

  • Small non-coding RNA and cancer
    • Authors: Romano G; Veneziano D, Acunzo M, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>The ENCODE project has reported that at least 80% of the human genome is biologically active, yet only a small part of human DNA encodes for protein. The massive amount of RNA transcribed but not translated into protein can be classified as housekeeping RNA (such as rRNA, tRNA) and regulatory RNA (such as miRNA, piRNA, lncRNA). Small non-coding RNAs, in particular, have been the focus of many studies in the last 20 years and their fundamental role in many human diseases is currently well established. Inter alia, their role in cancer development and progression, as well as in drug resistance, is being increasingly investigated. In this review, focusing our attention on recent research results, we provide an overview of the four large classes of small non-coding RNAs, namely, miRNAs, piRNAs, snoRNA and the new class of tRNA-derived fragments, highlighting their fundamental role in cancer and their potential as diagnostic and prognostic biomarkers.</span>

  • Evaluating genetic variants associated with breast cancer risk in high and
           moderate-penetrance genes in Asians
    • Authors: Han M; Zheng W, Cai Q, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Over the past 20 years, high-penetrance pathogenic mutations in genes <span style="font-style:italic;">BRCA1</span>, <span style="font-style:italic;">BRCA2</span>, <span style="font-style:italic;">TP53</span>, <span style="font-style:italic;">PTEN</span>, <span style="font-style:italic;">STK11</span> and <span style="font-style:italic;">CDH1</span> and moderate-penetrance mutations in genes <span style="font-style:italic;">CHEK2, ATM, BRIP1, PALB2</span>, <span style="font-style:italic;">RAD51C, RAD50</span> and <span style="font-style:italic;">NBN</span> have been identified for breast cancer.

We analyzed up to 654 single nucleotide polymorphisms (SNPs) from 6269 cases and 6624 controls of Asian descent included in the Breast Cancer Association Consortium (BCAC), and up to 236 SNPs from 5794 cases and 5529 controls included in the Shanghai Breast Cancer Genetics Study (SBCGS). We found three missense variants with minor allele frequency (MAF) <0.05: rs80358978 (Gly2508Ser), rs80359065 (Lys2729Asn) and rs11571653 (Met784Val) in the <span style="font-style:italic;">BRCA2</span> gene, showing statistically significant associations with breast cancer risk, with <span style="font-style:italic;">P</span>-values of 1.2 × 10<sup>–4</sup>, 1.0 × 10<sup>–3</sup> and 5.0 × 10<sup>–3</sup>, respectively. In addition, we found four low-frequency variants (rs8176085, rs799923, rs8176173 and rs8176258) in the <span style="font-style:italic;">BRCA1</span> gene, one common variant in the <span style="font-style:italic;">CHEK2</span> gene (rs9620817), and one common variant in the <span style="font-style:italic;">PALB2</span> gene (rs13330119) associated with breast cancer risk at <span style="font-style:italic;">P</span> < 0.01. Our study identified several new risk variants in <span style="font-style:italic;">BRCA1</span>, <span style="font-style:italic;">BRCA2, CHEK2,</span> and <span style="font-style:italic;">PALB2</span> genes in relation to breast cancer risk in Asian women. These results provide further insights that, in addition to the high/moderate penetrance mutations, other low-penetrance variants in these genes may also contribute to breast cancer risk.</span>

  • Functional variants in DCAF4 associated with lung cancer risk in European
    • Authors: Liu H; Liu Z, Wang Y, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Cullin-RING ubiquitin ligases (CRLs) responsible for substrate specificity of ubiquitination play a key role in cell-cycle control and DNA damage response. In this study, we assessed associations between 16 599 SNPs in 115 CRL genes and lung cancer risk by using summary data of six published genome-wide association studies (GWASs) of 12 160 cases and 16 838 cases of European ancestry. As a result, we identified three independent SNPs in <span style="font-style:italic;">DCAF4</span> (rs117781739, rs12587742 and rs2240980) associated with lung cancer risk (odds ratio = 0.91, 1.09 and 1.09, respectively; 95% confidence interval = 0.88–0.95, 1.05–1.14 and 1.05–1.13, respectively; and <span style="font-style:italic;">P</span> = 3.99 × 10<sup>–6</sup>, 4.97 × 10<sup>–5</sup> and 1.44 × 10<sup>–5</sup>, respectively) after multiple comparison correction by a false discovery rate <0.05. Since SNP rs12587742 is located within the promoter region and one CpG island of <span style="font-style:italic;">DCAF4</span>, we further performed <span style="font-style:italic;">in silico</span> functional analyses and found that the rs12587742 variant A allele was associated with an increased mRNA expression (<span style="font-style:italic;">P</span> = 2.20 × 10<sup>−16</sup>, 1.79 × 10<sup>−13</sup> and 0.001 in blood cells, normal lung tissues and tumor tissues of lung squamous carcinoma, respectively) and a decreased methylation status (<span style="font-style:italic;">P</span> = 2.48 × 10<sup>−9</sup> and 0.032 in adipose and lung tumor tissues, respectively). Moreover, evidence from differential expression analyses further supported an oncogenic effect of <span style="font-style:italic;">DCAF4</span> on lung cancer, with higher mRNA levels in both lung squamous carcinoma and adenocarcinoma (<span style="font-style:italic;">P</span> = 4.48 × 10<sup>−11</sup> and 1.22 × 10<sup>−9</sup>, respectively) than in adjacent normal tissues. Taken together, our results suggest that rs12587742 is associated with an increased lung cancer risk, possibly by up-regulating mRNA expression and decreasing methylation status of <span style="font-style:italic;">DCAF4</span>.</span>

  • Inactivation of JNK2 as carcinogenic factor in colitis-associated and
           sporadic colorectal carcinogenesis
    • Authors: Lessel W; Silver A, Jechorek D, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>We recently reported that dysregulated c-Jun <span style="font-style:italic;">N</span>-terminal kinases (JNK) activity causes defective cell cycle checkpoint control, inducing neoplastic transformation in a cellular ulcerative colitis (UC) model. In the quiescent chronic phase of UC, p-p54 JNK was down-regulated and p-p46 JNK was up-regulated. Both were up-regulated in the acute phase. Consequently, increased p21<sup>WAF1</sup> and γ-H2AX, two JNK-regulated proteins, induced cell cycle arrest. Their down-regulation led to checkpoint override, causing increased proliferation and undetected DNA damage in quiescent chronic phase, all characteristics of tumorigenesis. We investigated expression of p-JNK2, p-JNK1-3, p21<sup>WAF1</sup>, γ-H2AX and Ki67 by immunohistochemistry in cases of quiescent UC (QUC), active UC (AUC), UC-dysplasia and UC-related colorectal carcinoma (UC-CRC). Comparison was made to normal healthy colorectal mucosa, sporadic adenoma and colorectal carcinoma (CRC), diverticulitis and Crohns disease (CD). We found p-JNK2 up-regulation in AUC and its early down-regulation in UC-CRC and CRC carcinogenesis. With down-regulated p-JNK2, p21<sup>WAF1</sup> was also decreased. Ki67 was inversely expressed, showing increased proliferation early in UC-CRC and CRC carcinogenesis. p-JNK1-3 was increased in AUC and QUC. Less increased γ-H2AX in UC-CRC compared to CRC gave evidence that colitis-triggered inflammation masks DNA damage, thus contributing to neoplastic transformation. We hypothesize that JNK-dependent cell cycle arrest is important in AUC, while chronic inflammation causes dysregulated JNK activity in quiescent phase that may contribute to checkpoint override, promoting UC carcinogenesis. We suggest restoring p-JNK2 expression as a novel therapeutic strategy to early prevent the development of UC-related cancer.</span>

  • Human mitochondrial pyrroline-5-carboxylate reductase 1 promotes
           invasiveness and impacts survival in breast cancers
    • Authors: Ding J; Kuo M, Su L, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Human mitochondrial pyrroline-5-carboxylate reductase (PYCR) is a house-keeping enzyme that catalyzes the reduction of Δ1-pyrroline-5-carboxylate to proline. This enzymatic cycle plays pivotal roles in amino acid metabolism, intracellular redox potential and mitochondrial integrity. Here, we hypothesize that <span style="font-style:italic;">PYCR1</span> might be a novel prognostic biomarker and therapeutic target for breast cancer. In this study, breast cancer tissue samples were obtained from Zhejiang University (ZJU set). Immunohistochemistry analysis was performed to detect the protein level of PYCR1, and Kaplan–Meier and Cox proportional analyses were employed in this outcome study. The prognostic significance and performance of <span style="font-style:italic;">PYCR1</span> mRNA were validated on 13 worldwide independent microarray data sets, composed of 2500 assessable breast cancer cases. Our findings revealed that both <span style="font-style:italic;">PYCR1</span> mRNA and protein expression were significantly associated with tumor size, grade and invasive molecular subtypes of breast cancers. Independent and pooled analyses verified that higher <span style="font-style:italic;">PYCR1</span> mRNA levels were significantly associated with poor survival of breast cancer patients, regardless of estrogen receptor (ER) status. For <span style="font-style:italic;">in vitro</span> studies, inhibition of <span style="font-style:italic;">PYCR1</span> by small-hairpin RNA significantly reduced the growth and invasion capabilities of the cells, while enhancing the cytotoxicity of doxorubicin in breast cancer cell lines MCF-7 (ER positive) and MDA-MB-231 (ER negative). Further population study also validated that chemotherapy significantly improved survival in early-stage breast cancer patients with low PYCR1 expression levels. Therefore, <span style="font-style:italic;">PYCR1</span> might serve as a prognostic biomaker for either ER-positive or ER-negative breast cancer subtypes and can also be a potential target for breast cancer therapy.</span>

  • Reduced mRNA expression of nucleotide excision repair genes in lymphocytes
           and risk of squamous cell carcinoma of the head and neck
    • Authors: Han P; Gao F, Liu H, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Nucleotide excision repair (NER) plays a critical role in the development of smoking-related cancers. We hypothesize that mRNA expression levels of NER genes are associated with risk of the squamous cell carcinoma of head and neck (SCCHN). To test this hypothesis, we conducted a case-control study of 260 SCCHN patients and 246 cancer-free controls by measuring the mRNA expression levels of eight core NER genes in cultured peripheral lymphocytes. Compared with the controls, cases had statistically significantly lower expression levels of <span style="font-style:italic;">DDB1</span> and <span style="font-style:italic;">ERCC3</span> (<span style="font-style:italic;">P</span> = 0.015 and 0.041, respectively). Because <span style="font-style:italic;">DDB1</span> and <span style="font-style:italic;">ERCC3</span> expression levels were highly correlated, we used <span style="font-style:italic;">DDB1</span> for further multivariate analyses and modeling. After dividing the subjects by controls’ quartiles of expression levels, we found an association between an increased risk of SCCHN and low <span style="font-style:italic;">DDB1</span> expression levels [adjusted ORs and 95% CIs: 1.92 and 1.11–3.32, 1.48 and 0.85–2.59, 2.00 and 1.15–3.45 for the 2<sup>nd</sup>–4<sup>th</sup> quartiles, respectively, compared with the 1<sup>st</sup> quartile; <span style="font-style:italic;">P</span><sub>trend</sub> = 0.026]. We also identified a multiplicative interaction between sex and <span style="font-style:italic;">DDB1</span> expression levels (<span style="font-style:italic;">P</span> = 0.007). Finally, the expanded model with gene expression levels, in addition to demographic and clinical variables, on SCCHN risk was significantly improved, especially among men. In conclusion, reduced <span style="font-style:italic;">DDB1</span> expression levels were associated with an increased risk of SCCHN. However, these results need to be validated in larger studies.</span>

  • Associations between single nucleotide polymorphisms in RYBP and the
           prognosis of hepatocellular carcinoma in a Chinese population
    • Authors: Zhu X; Wang Z, Qiu X, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Down-regulated RINGl and YYl binding protein (RYBP) is reported to be an independent predictor of a poor prognosis in patients with hepatocellular carcinoma (HCC). However, the genetic association of <span style="font-style:italic;">RYBP</span> polymorphisms with HCC risk and prognosis has not been investigated now. In this study, five <span style="font-style:italic;">RYBP</span> SNPs, rs12956, rs2118593, rs17009699, rs4676875 and rs4532099, were studied from a hospital-based case-control study including 1100 cases (HCC patients) and 1100 controls (non-HCC patients) in Guangxi, China. All these SNPs interacted with environmental risk factors, such as HBV infection, alcohol intake and smoking in the pathogenesis of HCC. Compared to the CC genotype, patients with TT genotype of rs12956 had a decreased risk of HCC (OR = 0.587, 95% CI = 0.403~0.923) and an increased survival time (Co-dominant, HR = 0.745, 95% CI = 0.594~0.934), while those with TT genotype of rs2118593 had an increased risk of HCC (OR = 1.538, 95% CI = 1.093~2.735) and a decreased survival time (Co-dominant, HR = 1.447, 95% CI = 1.174~1.782). No significant difference was found between the other three <span style="font-style:italic;">RYBP</span> polymorphisms with HCC risk and prognosis. Furthermore, we found that tumor number, tumor staging, metastasis and rs2118593 were associated with the overall survival of HCC patients by multivariate COX regression analysis. Our study suggests <span style="font-style:italic;">RYBP</span> SNP, rs2118593 as a new predictor for poor prognosis of HCC patients.</span>

  • Targeted sequencing of chromosome 15q25 identified novel variants
           associated with risk of lung cancer and smoking behavior in Chinese
    • Authors: Cheng Y; Wang C, Zhu M, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>Previous genome-wide association studies (GWAS) in populations of European descent identified a lung cancer susceptibility locus at 15q25 that was biologically associated with nicotine addiction. However, the allele frequency of susceptibility variants identified in this region varied dramatically across European and Asian populations, suggesting that additional risk single nucleotide polymorphism (SNPs) in Asians need to be identified. Thus, we conducted a fine-mapping study of chromosome 15q25 using targeted resequencing of 200 lung cancer cases and 300 controls of Chinese descent. An approximate conditional and joint analysis of the discovery data revealed two novel SNPs with independent effects (rs6495304: OR = 1.79, <span style="font-style:italic;">P</span> = 9.37 × 10<sup>−4</sup>; and rs74733525: OR = 1.68, <span style="font-style:italic;">P =</span> 8.05 × 10<sup>−3</sup>). Both variants were common in Asians but rare or monomorphic in Whites. These results were further supported by <span style="font-style:italic;">in silico</span> validation including 8047 cases and 8898 controls from multiethnic lung cancer genome-wide association studies (GWASs) (rs6495304: OR = 1.32, <span style="font-style:italic;">P</span> = 1.21 × 10<sup>–11</sup>; and rs74733525: OR = 1.29, <span style="font-style:italic;">P</span> = 4.29 × 10<sup>−4</sup>); however, rs6495304 demonstrated significant effects only in ever-smokers (<span style="font-style:italic;">P</span> = 0.004 for heterogeneity test of smoking). Mediation analysis indicated that smoking behavior may mediate the effect of rs6495304 on lung cancer risk. Furthermore, expression quantitative trait loci analysis showed the risk allele (A) of rs6495304 was significantly associated with lower mRNA expression of <span style="font-style:italic;">CHRNA3</span> (<span style="font-style:italic;">P</span> = 0.029) in 81 hypothalamic tissue samples. This finding provides new insights into the association between lung cancer susceptibility and the 15q25 locus.</span>

  • In bone metastasis miR-34a-5p absence inversely correlates with Met
           expression, while Met oncogene is unaffected by miR-34a-5p in
           non-metastatic and metastatic breast carcinomas
    • Authors: Maroni P; Puglisi R, Mattia G, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>The highlight of the molecular basis and therapeutic targets of the bone-metastatic process requires the identification of biomarkers of metastasis colonization. Here, we studied miR-34a-5p expression, and Met-receptor expression and localization in bone metastases from ductal breast carcinomas, and in ductal carcinomas without history of metastasis (20 cases). miR-34a-5p was elevated in non-metastatic breast carcinoma, intermediate in the adjacent tissue and practically absent in bone metastases, opposite to pair-matched carcinoma. Met-receptor biomarker was highly expressed and inversely correlated with miR-34a-5p using the same set of bone-metastasis tissues. The miR-34a-5p silencing might depend on aberrant-epigenetic mechanisms of plastic-bone metastases, since in 1833 cells under methyltransferase blockade miR-34a-5p augmented. In fact, 1833 cells showed very low endogenous miR-34a-5p, in respect to parental MDA-MB231 breast carcinoma cells, and the restoration of miR-34a-5p with the mimic reduced Met and invasiveness. Notably, hepatocyte growth factor (HGF)-dependent Met stabilization was observed in bone-metastatic 1833 cells, consistent with Met co-distribution with the ligand HGF at plasma membrane and at nuclear levels in bone metastases. Met-protein level was higher in non-metastatic (low grade) than in metastatic (high grade) breast carcinomas, notwithstanding miR-34a-5p-elevated expression in both the specimens. Thus, mostly in non-metastatic carcinomas the elevated miR-34a-5p unaffected Met, important for invasive/mesenchymal phenotype, while possibly targeting some stemness biomarkers related to metastatic phenotype. In personalized therapies against bone metastasis, we suggest miR-34a-5p as a suitable target of epigenetic reprogramming leading to the accumulation of miR-34a-5p and the down-regulation of Met-tyrosine kinase, a key player of the bone-metastatic process.</span>
