BACKGROUND microRNAs (miRNAs) play a significant role in cancer development and progression by regulating the expression of oncogenes or tumor suppressor genes. Previous study using microarrays demonstrated that miR-142-3p was downregulated in patients with Non-small-cell lung carcinoma (NSCLC). However, the functional role of miR-142-3p in NSCLC is still unclear. MATERIAL AND METHOD Real-tim...

MicroRNAs regulate most protein-coding genes, including genes important in cancer and other diseases. In this study, we demonstrated that the expression of miR-142 could be significantly suppressed in pancreatic cancer specimens and cell lines compared to their adjacent tissues and normal pancreatic cells. Growth and invasion of PANC-1 and SW1990 cells were attenuated by overexpression of miR-1...

BACKGROUND/AIMS An increasing number of studies show that microRNAs (miRNAs) play crucial roles in nasopharyngeal carcinoma (NPC) tumorigenesis. The aim of our study was to investigate the biological roles and mechanisms of miR-142-3p in NPC. METHODS miR- 142-3p expression was examined in NPC specimens and nasopharyngitis biopsy samples by quantitative real-time PCR. The biological functions ...

Snakebite is a common problem especially in tropical areas all over the world includingIran. Echis carinatus as one of the most dangerous Iranian snakes is spreading in this countryexcluding central and northwest provinces. In this study gelatinase and fibrinogenolyticproperties as two disintegrating matrix metalloproteinase enzymes were evaluated by a strongclear halo between 56-72 kDa in addi...

MicroRNA (miR)‑142‑5p is a member of the miR‑142 family, which have been shown to be associated with tumors, stem cells and disorders of the immune system. However, the role of miR‑142‑5p in atherosclerosis has yet to be investigated. In the present study, an atherosclerotic apolipoprotein E‑deficient (apoE‑/‑) mouse model was constructed and fed a high‑fat diet. The expression levels of miR‑14...

MicroRNAs (miRNAs) are short 18-23 nucleotide long noncoding RNAs that posttranscriptionally regulate gene expression by binding to mRNA. Our previous miRNA profiling of diffuse large B-cell lymphoma (DLBCL) revealed a mutation in the seed sequence of miR-142-3p. Further analysis now showed that miR-142 was mutated in 11 (19.64%) of the 56 DLBCL cases. Of these, one case had a mutation in both ...

certainty although its general position is reasonably well defined. In the energy refinement, this part of the structure contracts and attempts to fold back onto the N-terminal domain, leading not only to a large movement as found in other external loops but also a large conformational change in the main chain. Re-examination of this loop has shown that an alternative local conformation can be ...

Treatment of chicken blood smears and semithin sections from Epon-embedded mouse tissues with aqueous solutions of the 3-aminonaphthalimides FA-142, FA-2043, and FA-2143 induced a strong green-yellow fluorescence of chromatin under violet or violet-blue excitation. Chromatin emission was abolished by previous DNase or hot TCA treatment. The use of 3-methoxy (FA-655) and 3-nitro derivatives (M-4...

The rational design of inhibitors of human renin for the treatment of hypertension depends on a detailed knowledge of the renin-angiotensinogen transition-state complex. Direct determination of the three-dimensional structure of complexes of human renin with transition state analogues is not possible until large quantities of human renin are made available by recombinant DNA techniques. Neverth...
