           Antibodies

      Pages: 41 - 9
      Abstract: Lung cancer is the most contributor of cancer cause death in the world. Lung cancer is related to cigarette consumption and genetic factor. Nicotine derived nitrosamine ketone is the most important inducer of lung cancer associated with DNA Mutations resulting in the activation of Kirsten rat sarcoma viral (KRAS) oncogenes. DNA Mutation in Lung cancer is mostly presence by epidermal growth factor receptor (EGFR) mutations. There were seven potential biomarkers to detect early lung cancer, whereas carcinoembryonic antigen (CEA), neuron specific enolase (NSE), cytokeratin-19 fragments (CYFRA 21-1), alpha-fetoprotein (AFP), cancer antigen 125 (CA-125), CA-199 and ferritin. The use of biomarkers in combination can improve the accuracy in diagnosing lung cancer. Other biomarkers include KRAS mutations, B-type Raf kinase (BRAF) mutation, mesenchymal-epithelial transition factor (MET) amplification and Excision repair cross-complementing group 1 (ERCC1) can be used to see whether there are any genetic mutations that lead to lung cancer. Treatment of lung cancer with chemotherapy can be done using tyrosine kinase inhibitors and monoclonal antibodies.Keywords: lung cancer, DNA mutation, EGFR, KRAS, BRAF, MET, tyrosine kinase

  • Dental Mesenchymal Stem Cell: Its role in tooth development, types,
           surface antigens and differentiation potential

      Pages: 50 - 7
      Abstract: Reciprocal interaction between oral ectodermal epithelial cells and mesenchymal stem cells (MSCs)-derived from the cranial neural crest starts the teeth development. The role of dental MSCs continues throughout life. The dental MSCs do not only play a role in tooth development but also in tooth homeostasis and repair. There are many kinds of dental MSCs, such as dental pulp stem cell (DPSC), stem cell from apical papilla (SCAP), stem cell from exfoliated deciduous teeth (SHED), periodontal ligament stem cell (PDLSC) and stem cell from dental follicle (DFSC). Aligned with the proposed criteria by the International Society for Cellular Therapy (ISCT), dental MSCs are adherent cells and like other MSCs, dental tissue MSCs are capable of giving rise to cell lineages such as osteo/odontogenic, adipogenic, and neurogenic. Various surface antigens of dental MSCs were reported, however, mostly typical antigens suggested by ISCT were fulfilled. Surface antigens from each dental MSCs (DPSC, SCAP, SHED, PDLSC and DFSC) are being described in the current report.Keywords: dental stem cells, mesenchymal stem cells, tissue regeneration, DPSC, SCAP, SHED, PDLSC, DFSC

  • Autoantibodies in Diabetes Mellitus

    • Authors: Eka Herawati, Ardian Susanto, Christina Noventy Sihombing
      Pages: 58 - 64
      Abstract: Based on American Diabetes Association (ADA), diabetes can be classified into the following general categories: type 1 diabetes (T1D), type 2 diabetes (T2D), gestational diabetes mellitus (GDM) and specific types of diabetes due to other cause. Obesity is by far the main underlying factor causing T2D and its pathological potential lies in obesity-associated insulin resistance, activation of innate immunity and chronic low-grade inflammation. When tissue inflammation induced, tissue destruction occurs, 'self' antigens, which are generally not accessible to T cells, can be released from the affected tissues and promote autoimmune activation. The 4 major autoantibodies are islet-cell cytoplasmic autoantibodies (ICA), glutamid acid decarboxylase antibody (GADA), islet antigen-2 antibody (IA-2A) and insulin autoantibodies (IAA). In addition, ZnT8A has recently been found to predict T1D. ZnT8 is contained in the islets of Langerhans, with the highest expression is in β cells of the pancreas. ZnT8A measurements simultaneously with GADA, IA-2A and IAA achieve rates of 98% detection for onset level of autoimmune diabetes. Presence of antibodies in T2D also shows the potential serious complications compared with T2D without antibodies. The combination of GADA, IA-2A and ZnT8A can be suggested as the most powerful and cost-effective diagnostic approach in patients with T1D.Keywords: autoantibody, autoimmune, diabetes mellitus, ICA, GADA, IA-2A, IAA, ZnT8A

  • Human Umbilical Cord Blood Serum Has Higher Potential in Inducing
           Proliferation of Fibroblast than Fetal Bovine Serum

    • Authors: Ferry Sandra, Rita Lahirin
      Pages: 65 - 9
      Abstract: Background: Cytokines and growth factors were reported to play an important role in stimulating fibroblast proliferation. In vitro culture, fibroblast is mostly culture in medium containing fetal bovine serum (FBS).  Human umbilical cord blood (hUCB) has been reported to have low immunogenic property and potential in wound healing, so therefore hUCB serum (hUCBS) could be potential and were investigated in current study.Materials and Methods: Five hUCBs were collected from healthy volunteers with normal delivering procedure. hUCB was ex utero immediately collected from umbilical vein in vacutainers and processed. NIH3T3 cells were cultured in DMEM with 10% FBS or 5-20% hUCBS for 48 hours. Cells were then quantified using MTT assay. Protein concentration of FBS and hUCBS were quantified using Bradford assay.Results: NIH3T3 cells density grown in DMEM with 10% FBS was the lowest. NIH3T3 cells densities were increased along with the increment of hUCBS concentrations. MTT results showed that average number of NIH3T3 cells grown in DMEM with 10% FBS was 6,185±1,243. Meanwhile average numbers of NIH3T3 cells grown in DMEM with 5%, 10% and 20% hUCBS were 8,126±628, 9,685±313 and 12,200±304, respectively. Average numbers of NIH3T3 cells grown in DMEM with 5% hUCBS were significantly higher than the ones with 10% FBS (p=0.000). Bradford results showed that concentration of hUCBS was significantly higher than the one of FBS (p=0.000).Conclusion: hUCBS could induce higher proliferation rate of NIH3T3 cells than FBS. Hence hUCBS could be suggested as an alternate of FBS in inducing fibroblast.Keywords: NIH3T3, fibroblast, UCB, serum, FBS, proliferation

  • Relationship between sRAGE and hsCRP as Markers of Cardiovascular Disease
           Risk Factors in Diabetic and Non-Diabetic Men with Central Obesity

    • Authors: Rambu Beppy Hamuaty, Indriyanti Rafi Sukmawati, Ferry Sandra
      Pages: 70 - 4
      Abstract: Background: Interaction between advanced glycation end product (AGE) and receptor for AGE (RAGE) triggers the escalation of inflammatory cytokine expressions. High-sensitivity C-reactive protein (hsCRP), an important inflammatory marker, has been reported to be modulated by soluble RAGE (sRAGE). However, the relationship between hsCRP and sRAGE in diabetes was not clearly described. Therefore present study was conducted to determine the relationship between sRAGE with hsCRP in men with central obese diabetic and non-diabetic. Materials and Methods: Adult men aged 25-60 years with central obese diabetes and non-diabetes, were recruited. Patient’s profiles were collected before the physical and blood examination. Physical examinations were conducted by measuring waist/abdomen, blood pressure, height, and weight. The routine blood test was performed to obtain concentrations of fasting blood glucose, HbA1c, hsCRP and sRAGE level.Results: Fifty-seven subjects with central obese and waist size ≥90 cm were selected. It was found that hsCRP values were significantly different (p=0.000) in HbA1c <6.5% dan HbA1c ≥6.5% groups. There was an inverse relationship between hsCRP and sRAGE levels for both in HbA1c <6.5% (r=-0.073) and HbA1c≥6.5% (r=-0.022) groups. In HbA1c ≥6.5% group, sRAGE showed strong positive correlation with 1 mg/dL ≤ hsCRP <3 mg/dL group (r>0.5).Conclusions: In the early stages of diabetes with hsCRP <1 mg/dL, the protective function was demonstrated with greater sRAGE levels. However, in further phase with 3 ≤ hsCRP < 10 mg/dL, the level of sRAGE was low, which is assumed to be associated with complications. Hence, sRAGE could be suggested as a complementary marker for hsCRP to evaluate diabetic men with central obesity.Keywords: sRAGE, hsCRP, diabetes, HbA1c, central obesity
