Breast cancer is a leading cause of related death among women worldwide and it complex disease characterized by its heterogeneity. The heterogenous characteristic the breast responsible for aggressiveness treatment resistance. stem cells (BCSCs) are population with increased propensity proliferation, differentiation, migration, invasion mammosphere formation resistance to treatment. They have a...

MicroRNAs play essential roles in gene expression regulation during carcinogenesis. Here, we investigated the role of miR-7 and the mechanism by which it is dysregulated in gastric cancer (GC). We used genome-wide screenings and identified RELA and FOS as novel targets of miR-7. Overexpression of miR-7 repressed RELA and FOS expression and prevented GC cell proliferation and tumorigenesis. Thes...

Genome-encoded microRNAs (miRNAs) provide a post-transcriptional regulatory layer that is important for pancreas development. However, how specific miRNAs are intertwined into the transcriptional network, which controls endocrine differentiation, is not well understood. Here, we show that microRNA-7 (miR-7) is specifically expressed in endocrine precursors and in mature endocrine cells. We furt...

MicroRNA are short and non-coding RNA, 18-25 nucleotides in length. They produced at the early stage of viral infection. The roles played by cellular miRNAs miRNA-mediated gene-silencing COVID-19 epidemic period is critical order to develop novel therapeutics. We analyzed SARS-CoV-2 Surface Glycoprotein (S) nucleotide sequence originating from India as well Iran, Australia, Germany, Italy, Russ...

Elucidating the mechanism underlying the poor proliferative capacity of adult pancreatic β-cells is critical to regenerative therapeutic approaches for diabetes. Here, we show that the microRNA (miR)-7/7ab family member miR-7a is enriched in mouse adult pancreatic islets compared with miR-7b. Remarkably, miR-7a targets five components of the mTOR signaling pathway. Further, inhibition of miR-7a...

MicroRNAs (miRNAs) are aberrantly expressed in cervical cancer. miR-7 has been demonstrated to function as both an oncogene and a tumor suppressor in some types of human cancers. In the present study, miR-7 was significantly downregulated in cervical cancer, especially metastatic tumors. Ectopic expression of miR-7 significantly inhibited metastasis and invasion in Hela and C33A cells. Upregula...

Age-related defects in fibroblast differentiation were previously shown to be associated with impaired hyaluronan synthase 2 (HAS2) and epidermal growth factor receptor (EGFR) function, with both required for normal fibroblast functionality. In fibroblasts, transforming growth factor-beta 1 (TGF-β1)-dependent phenotypic activation uses two distinct but co-operating pathways that involve TGF-β r...

MicroRNAs(miRNAs) are emerging as important regulators in tumorigenesis. Increasing evidences have indicated microRNA-7(miR-7) to be a potential tumor suppressor in several human cancers. However, only a limited number of target genes have been identified so far and its biological function in Non-Small Cell Lung Cancer (NSCLC) remains to be further elucidated. In the present study, we observed ...

Recent evidence showed that microRNA-7 (miR-7) played an important role in the pathologies of lung-related diseases. However, the potential role of miR-7 in acute lung injury (ALI) still remains poorly understood. Here, we assessed the effect of miR-7 deficiency on the pathology of ALI. We, first, found that the expression of miR-7 was upregulated in lung tissue in murine LPS-induced ALI model....
