MicroRNAs (miRNAs) involved in regulation of the genes. The CCAAT/enhancer-binding protein-α (CEBPα) is a crucial transcription factor for normal hematopoiesis and cell cycle that frequently disrupted in human acute myeloid leukemia (AML). The miR-182 up-regulation in several malignant diseases such as AML was reported, in the other hand bioinformatics analysis revealed CEBPα targeted by miR-18...

Layered strategies to combat hypoxia provide flexibility in dynamic oxygen environments. Here we show that multiple miRNAs are required for hypoxic survival responses during C. elegans embryogenesis. Certain miRNAs promote while others antagonize the hypoxic survival response. We found that expression of the mir-35 family is regulated by hypoxia in a HIF-1-independent manner and loss of mir-35-...

OBJECTIVE Breast cancer (BC) is one of the most common malignant tumors occurred in women. There is no sensitive and specific marker for early diagnosis, treatment and prognosis of breast cancer. It is suggested that miRNA may be a potential tumor marker for breast cancer. Mir-520g is considered to be associated with many tumors. This study aims to test the expression of mir-520g in peripheral ...

PURPOSE Recent studies have suggested that microRNA biomarkers could be useful for stratifying lung cancer subtypes, but microRNA signatures varied between different populations. Squamous cell carcinoma (SCC) is one major subtype of lung cancer that urgently needs biomarkers to aid patient management. Here, we undertook the first comprehensive investigation on microRNA in Chinese SCC patients. ...

BACKGROUND The identification of novel biomarkers for early breast cancer detection would be a great advance. Because of their role in tumorigenesis and stability in body fluids, microRNAs (miRNAs) are emerging as a promising diagnostic tool. Our aim was to identify miRNAs deregulated in breast tumors and evaluate the potential of circulating miRNAs in breast cancer detection. METHODS We cond...

BACKGROUND microRNAs (miRNA) are 18-22 nucleotides long non-coding RNAs that regulate gene expression at a post-transcriptional level. Human cytomegalovirus (HCMV) encodes at least 26 known mature miRNAs. hcmv-miR-UL112-3p (miR-UL112-3p) is the most well characterized HCMV miRNA, which is suggested to play role in establishment and maintenance of viral latency. Elevated miR-UL112-3p levels have...

OBJECTIVE Estradiol (E2) regulates gene transcription by activating estrogen receptor-α and estrogen receptor-β. Many of the genes regulated by E2 via estrogen receptors are repressed, yet the molecular mechanisms that mediate E2-induced gene repression are currently unknown. We hypothesized that E2, acting through estrogen receptors, regulates expression of microRNAs (miRs) leading to repressi...

Objective(s): To explore the correlation between expression patterns and functions of miR-383 and LDHA in hepatocellular cancer (HCC). Materials and Methods: We detected the expression of miR-383 and LDHA in 30 HCC tissues and their matched adjacent normal tissues using qRT-PCR. Then we performed MTT assay, foci formation assay, transwell migration assay, glucose uptake assay and lactate produc...
