Colorectal cancer (CRC) is the third most frequently diagnosed malignancy worldwide. Currently, irinotecan (CPT-11) used alone or in combination with other drugs to treat patients advanced CRC. However, 5-year survival rate for metastatic CRC remains below 10 %, largely due chemotherapy resistance. Several genes, including ABCG2, CYP3A4, MCL1, and MLH1 contribute This study aimed identify microRNAs that simultaneously regulate expression of these genes irinotecan-resistant cell lines their...

It is observed that upregulation of DNMT3B enzyme in some cancers, including colon cancer, could lead to silencing tumor suppressor genes. MiR-339 and miR-766 have been predicted target 3′UTR gene. Luciferase reporter assay validated individual co-transfection miR-339 into the HEK293T cell reduced luciferase activity 26% ± 0.41%, 43% 0.42 64% 0.52%, respectively, compared control (P < 0.05). Furthermore, transduction expressing viruses cancer lines (SW480 HCT116) decreased expression (1.5,...

Oxaliplatin as a component of (Neo-) adjuvant chemotherapeutic regimens is administered to colorectal cancer patients. Unfortunately, the acquisition resistance this drug in nearly 90% metastatic patients rendered it an ineffective drug. Therefore, mechanisms should be elucidated. There are different genes like GSTP1 and ABCB1 which responsible for oxaliplatin resistance. We hypothesized that miR-129-5p, miR-302c-5p, miR-3664-5p, mir-3714 miR-513a-3p targeting gene, while was predicted...

Fc-fusion peptides, also known as peptibodies, are a promising new category of targeted therapeutics that offer alternatives to monoclonal antibodies (mAbs) for cancer treatment. This study focuses on an peptide consisting the Fc region IgG1 and epidermal growth factor receptor (EGFR)-targeting peptide, GE11, which was identified using phage display method demonstrated high affinity receptor. The fusion (FcIgG-GE11) successfully expressed in Escherichia coli purified ion-exchange...

Over the latest decade, role of microRNAs (miRNAs/miRs) has received more attention. miRNAs are small non-coding RNAs that may serve a as oncogenes or tumor suppressor genes. Certain regulate apoptosis pathway by influencing pro- anti-apoptotic We hypothesized increases in expression B cell lymphoma 2 (BCL2) and BCL2-like 1 (BCL2L1) genes, which have been reported various types cancer tissues, be due to downregulation certain miRNAs. The present study aimed identify target BCL2 BCL2L1 genes...
