OBJECTIVE MicroRNA-100 (miR-100) has been demonstrated to be downregulated in bladder cancer tissues, and enforced expression of this miRNA may inhibit cell growth and colony formation of human bladder cancer 5637 cells in vitro. However, the clinical significance of miR-100 in human bladder cancer has not yet been elucidated. Thus, the aim of this study was to investigate the diagnostic and pr...

BACKGROUND Small cell carcinoma of the cervix (SCCC) is very rare, and due to the long time period required to recruit sufficient numbers of patients, there is a paucity of information regarding the prognostic factors associated with survival. MicroRNAs (miRNAs) have been used as cancer-related biomarkers in a variety of tumor types, and the objective of this study was to determine whether micr...

objective(s):micrornas (mirnas) are a class of short rnas that control the biological processes including cell proliferation, apoptosis and development. aberrant expression of mirnas was determined in the different stages of tumor development and metastasis. to study the effect of silibinin on mirnas expression, we evaluated quantitative expression of mir-21 and mir-155 as two oncomirs and seve...

We found that restoration of miR-100 expression resulted in accumulation of LC3B-II and decrease of p62 in hepatocellular carcinoma (HCC) cells, whereas antagonism of miR-100 reduced the level of LC3B-II. Moreover, a significant correlation between miR-100 downregulation and p62 upregulation was observed in human HCC tissues, suggesting an autophagy-promoting effect of miR-100. Subsequent inves...

To the Editor: MicroRNAs (miRNAs) are small, non-coding RNA of 20–22 nucleotides in length which can silence specific target genes through direct mRNA degradation, translational repression, or both. miRNAs are involved in several cellular processes like cell cycle, apoptosis, drug resistance and differentiation. In 2011, Schotte et al. reported different miRNA signatures in pediatric acute lymp...

Evidence in literature has demonstrated that some microRNAs (miRNAs) play a pivotal role in most solid tumor metastasis. Previous studies have showed that miR-100 is downregulated in human prostate cancer tissue compared to normal prostate and also significantly decreased in bone metastatic prostate cancer samples compared with primary prostate cancer. Argonaute 2 (AGO2) is the core effector pr...

BACKGROUND Glioblastoma multiforme is one of the most deadly forms of brain cancer. We investigated the regulatory effects of microRNA-100 (miR-100) on cell proliferation, migration, and chemosensitivity in human glioblastoma. METHODS miR-100 expression was assessed by quantitative real-time polymerase chain reaction in both glioblastoma cells and human tumors. Lentiviruses of miR-100 mimics ...
