MicroRNAs as a New Molecular Biomarker for Diagnosis and Prognosis of T-cell Acute Lymphoblastic Leukemia (T-ALL): A Systematic Review
MicroRNAs (miRNAs, miRs) are small endogenous non-coding RNAs that regulate the expression of protein-encoding genes at the post-transcriptional level. Several studies have described the role of miRNAs in T-cell acute lymphoblastic leukemia (T-ALL), including tumor suppressor and oncogenic miRNAs. Down-regulation of miRNA expression is a prominent feature of human malignancy. This down-regulati...
متن کاملTumor Suppressor p53 Can Protect Normal Cells Against Dendrosomal Curcumin-Induced Apoptosis
Curcumin is a natural substance with anti-cancerous properties without many disadvantages of currently-used anticancer drugs. Its toxicity is significantly higher in tumor cells compared with normal cells. We hypothesized the difference of p53 function between normal and tumor cells as one of the presumable causes of this phenomenon. We knocked down the expression of p53 in normal fibrobl...
متن کاملmicroRNA-29a functions as a tumor suppressor in nasopharyngeal carcinoma 5-8F cells through targeting VEGF
Objective(s): microRNA-29 (miR-29) family miRNAs have been mentioned as tumor suppressive genes in several human cancers. The purpose of this study was to investigate the function of miR-29a in nasopharyngeal carcinoma (NPC) cells. Materials and Methods: Human NPC cell line 5-8F was transfected with mimic, inhibitor or scrambled controls...
متن کاملEvaluation of MicroRNA-99a and MicroRNA-205 Expression Levels in Bladder Cancer
Bladder cancer is the second most common cancer in the genitourinary tract, showing often recurrence and progresse into invasive states. Epigenetic changes, such as microRNA alteration are involved in bladder cancer tumorigenesis through a variety of signaling pathways. The epigenetic state depends on geographic and lifestyle conditions. The aim of this study was to investigate the expression l...
متن کاملDown-regulation of miR-135b in colon adenocarcinoma induced by a TGF-β receptor I kinase inhibitor (SD-208)
Objective(s):Transforming growth factor-β(TGF-β) is involved in colorectal cancer (CRC). The SD-208 acts as an anti-cancer agent in different malignancies via TGF-β signaling. This work aims to show the effect of manipulation of TGF-β signaling on some miRNAs implicated in CRC. Materials and Methods: We investigated the effects of SD-208 on SW-48, a colon adenocarcinoma cell line. The cell li...
