Determining that miRNAs play a role in breast cancer pathogenesis suggests it may be useful the diagnosis and treatment of cancer. In this study, 39 patients with invasive were diagnosed serum levels 20 miRNAs(miR-105, miR-21, miR-141, miR-200a, miR-200b, miR-200c, miR-203, miR-210, miR-375, miR-34a, miR-133a, miR-155, miR-139-5p, miR-143, miR-145, miR-365, miR-299-5p, miR-411, miR-452, miR-17)...
Accumulation of lipid droplets and inflammatory cell infiltration is the hallmark of nonalcoholic steatohepatitis (NASH). The roles of noncoding RNAs in NASH are less known. We aim to elucidate the function of miR-141/200c in diet-induced NASH. WT and miR-141/200c-/- mice were fed a methionine and choline deficient (MCD) diet for 2 weeks to assess markers of steatosis, liver injury, and inflamm...
BACKGROUND The association between Helicobacter pylori infection and gastric cancer has been identified recently. However, the molecular mechanism remained largely unknown. METHODS AND RESULTS We found that miR-141 was decreased in Helicobacter pylori positive specimens (n=75) compared with negative tissues (n=75). The knockdown of miR-141 enhanced the invasion ability of gastric cancer cells...
Exosomes from cancer cells, which contain microRNA and reach metastasis loci prior to cancer cells, stimulate the formation of a metastatic microenvironment. Previous studies have shown that exosomal miR-141-3p is associated with metastatic prostate cancer (PCa). However, the role and regulatory mechanism of miR-141-3p in the microenvironment of bone metastases require further study. In this st...
Predictive biomarkers for early diagnosis of prostate cancer are important its treatment. The functional microRNAs in the exosomes plasma and serum samples interest as stable non-invasive recurrence patients. present study aimed to clarify value exosomal miRNA-125a-5p miR-141-5p cancer. included 19 healthy individuals 31 In comparison levels controls, showed a slight increase patients (p=0.085)...
miR-141 confers docetaxel chemoresistance of breast cancer cells via regulation of EIF4E expression.
Resistance to docetaxel, a chemotherapy drug for breast cancer (BC) treatment, occurs in ~50% of patients, and the underlying molecular mechanisms of drug resistance are not fully understood. Gene regulation through miR-141 has been proven to play an important role in cancer drug resistance. The present study investigated the role of miR-141 expression in BC cells of acquired docetaxel resistan...
Colorectal cancer (CRC) is one of most common cancers and causes of cancer-associated mortality worldwide, due to its recurrence, metastasis and therapy resistance. Cancer stem cells (CSC) have been demonstrated to be vital for tumor initiation and recurrence. microRNAs may act as an oncogenes or tumor suppressors in numerous cancers. The present study demonstrated that microRNA-141 (miR‑141) w...
BACKGROUND One of the main issues in pathogenesis of MS is Th17/Treg imbalance. There are growing interests in nominating miRNAs involved in Th17 cell differentiation, suggesting them as new therapeutic agents that may reduce progression of different autoimmune diseases specially MS. OBJECTIVES We assessed transcript levels of miR-141 and miR-200a in MS patients, during relapsing and remittin...
The miR-200 family members have been implicated in stress responses and ovarian tumorigenesis. Here, we find that miR-200c/141 transcription is intimately linked to the transcription of the proximal upstream gene PTPN6 (SHP1) in all physiological conditions tested. PTPN6 and miR-200c/141 are transcriptionally co-regulated by two complementary mechanisms. First, a bypass of the regular PTPN6 pol...
The aim of our study was to monitor serum levels of two miRNAs (miR-21 and miR-141) and three KLKs (hK3/PSA, hK11, and hK13) before and 1, 5, and 30 days after radical prostatectomy, in order to characterize their fluctuations after surgery. 38 patients with prostate cancer were included. miR-21 and miR-141 were quantified through real-time PCR, while ELISA assays were used to quantify hK3 (PSA...
