We sought to characterize the pathway by which the multifunctional cytokine transforming growth factor-beta (TGF-beta) inhibits the proliferation of normal astrocytes, and we analyzed the alterations in the TGF-beta pathway in human glioma cell lines. Upon TGF-beta treatment, primary rat astrocytes showed a significant decrease in DNA synthesis upon thymidine incorporation with a cell cycle arr...
We examined the kenetics of p15 methylation and expression during myeloid development. We treated human cord blood CD34+ cells with either GM-CSF alone or in combination with stem cell factor and followed methylation at this locus using bisulfite genomic sequencing. CD34+ cells were found to be either fully methylated or completely unmethylated at 27 CpG dinucleotide sites in exon 1 and at 18 C...
background and aims: the latency-associated transcript (lat) transcribed by latent herpes simplex virus type-1 in neuron cells are able to influence their host cell pathways. while the most of previous studies were focused on anti-apoptotic effects of lat, our investigation is making an effort to explore lat potency on cell cycle pathway in neuroblastoma cell lines. methods: the evaluation of l...
Mink cells nonproductively transformed by the T-8 strain of mink cell focus-inducing virus express two type C viral amino terminal gag gene-coded structural proteins, p15 and p12, in the form of a 90,000 to 110,000 molecular weight polyprotein that lacks detectable immunological reactivity with other known type C virus-coded translational products. The observation concurs with the previous demo...
چکید ه سابقه و هدف در بدخیمیهای خونی، افزایش متیلاسیون در پروموتر ژنهای سرکوبگر تومور به عنوان یکی از رخدادهای شایع در مسیر اپیژنتیک گزارش شده است که قابل بازگشت میباشد. هدف از این مطالعه ارزیابی، میزان بسامد متیلاسیون پروموتر ژن P15 در بیماران مبتلا به لوسمی میلوئید حاد و بررسی ارتباط متیلاسیون پروموتر ژن P15 با بیان آن بود. مواد و روشها در یک مطالعه مقطعی، بیماران مراجعهکن...
To clarify the molecular basis of severe acute respiratory syndrome coronavirus (SARS-CoV) adaptation to different host species, we serially passaged SARS-CoV in rat angiotensin-converting enzyme 2 (ACE2)-expressing cells. After 15 passages, the virus (Rat-P15) came to replicate effectively in rat ACE2-expressing cells. Two amino acid substitutions in the S2 region were found on the Rat-P15 S g...
MXDs are transcription repressors that antagonize MYC-mediated gene activation. MYC, when associated with MIZ1, acts also as a repressor of subset genes, including p15 and p21. A role for in regulation MYC-repressed genes is not known. We report activate p21 U2OS cells. This activation required DNA binding by their interaction MIZ1. MXD mutants deficient MIZ1 interacted the MYC-binding partner ...
PURPOSE The cell cycle inhibitor p15(INK4b) has been localized in migrating corneal epithelial cells. In this study, TAT-fusion protein technology was used to transduce p15(INK4b) into human corneal epithelial cells to examine the effect on cell proliferation and migration. METHODS Human p15(INK4b), obtained by RT-PCR, was cloned into a TAT-HA vector, and the fusion protein was purified from ...
Variation on chromosome 9p21 is associated with risk of coronary artery disease (CAD). This genomic region contains the CDKN2A and CDKN2B genes which encode the cell cycle regulators p16(INK4a), p14(ARF) and p15(INK4b) and the ANRIL gene which encodes a non-coding RNA. Vascular smooth muscle cell (VSMC) proliferation plays an important role in the pathogenesis of atherosclerosis which causes CA...
Although numerous somatic mutations that contribute to the pathogenesis of childhood acute lymphoblastic leukemia (ALL) have been identified, no specific cytogenetic or molecular abnormalities are known to be consistently associated with relapse. The p16INK4A (p16), which encodes for both p16INK4A and p19ARF proteins, and p15INK4B (p15) genes are inactivated by homozygous deletion and/or p15 pr...
