Previously, we reported that the addition of seminal plasma proteins before cold-shock treatment prevents sperm membrane injury, and that 2 proteins of approximately 14 (P14) and 20 (P20) kDa, the main components of fraction 6 isolated by exclusion chromatography, are responsible for this protective effect. The objective of the present study was to localize P14 and P20 in tissues of the ram rep...
The two distinct proteins encoded by the CDKN2A locus are specified by translating the common second exon in alternative reading frames. The product of the alpha transcript, p16(INK4a), is a recognized tumour suppressor that induces a G1 cell cycle arrest by inhibiting the phosphorylation of the retinoblastoma protein by the cyclin-dependent kinases, CDK4 and CDK6. In contrast, the product of t...
Cell migration is mediated by the dynamic remodeling of focal adhesions (FAs). Recently, an important role of endosomal signaling in regulation of cell migration was recognized. Here, we show an essential function for late endosomes carrying the p14-MP1 (LAMTOR2/3) complex in FA dynamics. p14-MP1-positive endosomes move to the cell periphery along microtubules (MTs) in a kinesin1- and Arl8b-dep...
CDK5 regulatory subunit associated protein 3 (CDK5RAP3) is a novel activator of PAK4 and processes important pro-metastatic function in hepatocarcinogenesis. However, it remains unclear if there are other mechanisms by which CDK5RAP3 promotes HCC metastasis. Here, we showed that in CDK5RAP3 stable knockdown SMMC-7721 HCC cells, p14(ARF) tumor suppressor was upregulated at protein and mRNA level...
A phenotypically normal mother had two apparently balanced translocations involving chromosomes 5, 7, and 12. Her karyotype was 46,XX,t(5;7) (5;12) (p14q34;p14;q21), while her daughter, who was also phenotypically normal, had inherited only one of the translocations. Her karyotype was 46,XX,-5,-7,+rec(5)t(5;7) (q34;p14)mat,+der(7)t(5;7) (q34;p14)mat. The other was lost during a meiotic crossing...
Idiopathic pulmonary fibrosis (IPF) is a devastating lung disease of unknown etiology. A conspicuous feature is the formation and persistence of fibroblastic/myofibroblastic foci throughout the lung parenchyma. Mechanisms remain unknown, but data indicate that fibroblasts acquire an antiapoptotic phenotype. We hypothesized that transcriptional silencing of proapoptotic genes may be implicated, ...
زمینه و هدف: کیست هیداتیک در اثر آلودگی با لارو انگل اکینوکوکوس گرانولوزوس ایجاد میشود. در مرحله لاروی این انگل آنتیژنهای متعددی تولید میشود که یکی از این آنتیژنها، آنتیژنی از خانواده پروتئینهای p14-3-3 میباشد و واکسن نوترکیب آن ایمنی‌زایی قابل توجهی را در موش القا کرده است. با توجه به ایمونوژنتر بودن نواحی اپیتوپی آنتیژنها و تولید پاسخ ایمنی Th1 مطلوب هدف از این مطالعه کلون کردن ...
Background and purpose: Ghrelin, a natural ligand of the growth hormone secretagogue receptor plays a major role in regulation of appetite, body fat mass, and energy balance in the body. The aim of this study was to evaluate the effects of maternal diabetes on circulatory ghrelin levels in rat newborns. Materials and methods: In this experimental study, female Wistar rats were allocated into d...
BACKGROUND This meta-analysis was performed to investigate the relationship between methylation of the P14 and O6-methylguanine-DNA methyltransferase (MGMT) genes and the risk of hepatocellular carcinoma (HCC). MATERIALS AND METHODS We searched PubMed, EMBASE, the Chinese Biomedical Database (CBM), and the China National Knowledge Infrastructure (CNKI) databases to identify relevant studies t...
