آپوپتوز یا مرگ برنامه ریزی شده سلول یک نوع از مرگ سلولی می باشد که موجودات چند سلولی جهت حذف سلول های نا مناسب از آن استفاده می نمایند. نکته مهم در خلال حذف این نوع سلول ها این است که فرایند آپوپتوز به حدی کنترل شده و ایمن باشد که به ساختارهای مجاور هیچ نوع آسیبی وارد نشود. در این مطالعه با استفاده از دیدگاه protein complementation assay و تکنولوژی گزارشگر های دو بخشی لوسیفراز یک روش سلولی جدید...
Caspase-independent death mechanisms have been shown to execute apoptosis in many types of neuronal injury. P53 has been identified as a key regulator of neuronal cell death after acute injury such as DNA damage, ischemia, and excitotoxicity. Here, we demonstrate that p53 can induce neuronal cell death via a caspase-mediated process activated by apoptotic activating factor-1 (Apaf1) and via a d...
To identify low-penetrance susceptibility alleles for chronic lymphocytic leukemia (CLL), we performed a case-control study genotyping 768 single-nucleotide polymorphisms (SNP) in 692 cases of CLL and 738 controls. We investigated nonsynonymous SNPs, SNPs with potential functional effect, and tag SNPs in regulatory gene regions in a total of 172 genes involved in cancer biology. After adjustmen...
Nucleot ides : saviors of the cel l N ucleotides are the building blocks of DNA and the cell’s energy currency. Now, a report by Dhyan Chandra, Dean Tang (University of Texas, Smithville, TX), and colleagues reveals that these multifunctional molecules are also bodyguards, protecting healthy cells from apoptosis. The apoptotic cascade unfolds when failing mitochondria leak cytochrome c (cyt c),...
BACKGROUND Histone deacetylation, a common hallmark in malignant tumors, strongly alters the transcription of genes involved in the control of proliferation, cell survival, differentiation and genetic stability. We have previously shown that HDAC1, HDAC2, and HDAC3 (HDAC1-3) genes encoding histone deacetylases 1-3 are upregulated in primary human hepatocellular carcinoma (HCC). The aim of this ...
BACKGROUND/AIMS Conjugated linoleic acids (CLAs) are known to induce apoptosis in adipocytes; however, the cellular mechanisms involved remained illdefined. We explored the different apoptotic induction effects of two CLA isomers on adipocytes and then investigated the expression and function of microRNAs (miRNAs) related to the apoptosis. METHODS TUNEL and FCM assays were used to detect CLAs...
