Hsa-miR-513b-5p suppresses cell proliferation and promotes P53 expression by targeting IRF2 in testicular embryonal carcinoma cells.
In this study, we found that hsa-miR-513b-5p was highly expressed in the testes of infertile males with maturation arrest compared with normal controls. Overexpression of hsa-miR-513b-5p suppressed testicular embryonal carcinoma (NT2) cell proliferation and induced apoptosis in vitro, whereas silencing of hsa-miR-513b-5p reversed these effects. In addition, we found that interferon regulatory transcription factor 2 (IRF2) was a direct and functional target of hsa-miR-513b-5p. Silencing of endogenous IRF2 enhanced hsa-miR-513b-5p-mediated effects on cell proliferation in NT2 cells, whereas overexpression of IRF2 reversed these effects. Moreover, immunoblotting showed that overexpression of hsa-miR-513b-5p or silencing of endogenous IRF2 could promote the expression of P53. Moreover, overexpression of hsa-miR-513b-5p in the absence of p53 could also induce cell apoptosis. Together, our results suggest that hsa-miR-513b-5p suppresses NT2 cell proliferation and promotes P53 protein expression by targeting IRF2, and abnormal testicular hsa-miR-513b-5p expression may contribute to maturation arrest.

Authors: Peng C, Cohen DJ Abstract INTRODUCTION: Esophageal squamous cancer remains an important cause of mortality worldwide with two new immunotherapy drugs recently approved for metastatic disease. AREAS COVERED: The authors review the epidemiology and genomics of esophageal squamous cell carcinoma. They also examine prior trials involving targeted agents under investigation as well immunotherapies that have been approved and novel combinations. EXPERT OPINION: Great advances have been made in characterizing the molecular changes in esophageal carcinoma. However, relatively few drugs have shown benefit i...

ConclusionWe consider that this technique is useful, however, we have to exercise care in malignant cases as the true-positive rate may be low.
ConclusionThe more invasive approach does not correlate to a better outcome. In selected cases, DR is an oncologically safe technique; EBR is still a valid option to treat advanced oral cancers
ConclusionsThe expression level of MALAT1 is closely related with progression of tongue SCC. Furthermore, MALAT1 can serve as an independent biomarker for prognostic evaluation of tongue SCC.
ConclusionTherefore,HOTTIP acting as ceRNAs to promote testicular embryonal carcinoma cell proliferation.

Ott Research Institute of Obstetrics, Gynecology and Reproductology, Saint Petersburg, Russia 2Department of Genetics and Biotechnology, Saint Petersburg State University, Saint Petersburg, Russia In the present review, we focus on the phenomenon of chromothripsis, a new type of complex chromosomal rearrangements. We discuss the challenges of chromothripsis detection and its distinction from other chromoanagenesis events. Along with already known causes and mechanisms, we introdu...
UCLA researchers have made new inroads into understanding germ cell tumors, a diverse and rare group of cancers that begin in germ cells — the cells that develop into sperm and eggs. The researchers developed a protocol to recreate germ cell tumor cells from stem cells and used the new model to study the genetics of the cancer.Their findings could point the way toward new drugs to treat germ cell tumors, which account for around 3 percent of all cases of childhood and adolescent cancer.The study, published in Stem Cell Research, was led by Amander Clark, a UCLA professor of molecular cell and developmental biology an...
