Cytotoxic T lymphocytes (CTL) can induce apoptosis through a granzyme B-based killing mechanism. Here we show that in cells undergoing apoptosis by granzyme B, both p45 pro-interleukin 1 beta converting enzyme (ICE) and pro-CPP32 are processed. Using ICE deficient (ICE -/-) mice, embryonic fibroblasts exhibit high levels of resistance to apoptosis by granzyme B or granzyme 3, while B lymphoblas...
Control of RNA processing plays a major role in HIV-1 gene expression. To explore the role of several hnRNP proteins in this process, we carried out a siRNA screen to examine the effect of depletion of hnRNPs A1, A2, D, H, I and K on HIV-1 gene expression. While loss of hnRNPs H, I or K had little effect, depletion of A1 and A2 increased expression of viral structural proteins. In contrast, red...
Butyric acid (BA) is known to induce overexpression of fetal hemoglobin and then erythroid differentiation. Therefore, BA is currently under clinical investigation as a potential therapy for the treatment of sickle cell disease and cancer. Nevertheless, the molecular mechanisms involved in BA-induced differentiation remain largely unknown. Previous reports have shown that BA-induced overexpress...
this study was carried out to determine effects of phosphorus residual applied to wheat on vetch (vicia panonioca) growth, yields and some soil physical, chemical properties in soil. the experiment was conducted with randomized completely block design in a field with three replications including four levels of p residual (applied for wheat p0, p15, p30, and p45 kg p2o5 in hectare) from tripl...
Golgi-impregnated neurons from rat perirhinal cortex (PR) were classified into one of 15 distinct morphological categories (N = 6,891). The frequency of neurons in each cell class was determined as a function of the layer of PR and the age of the animal, which ranged from postnatal day 0 (P0) to young adulthood (P45). The developmental appearance of Golgi-impregnated neurons conformed to the ex...
Ty1 Gag comprises the capsid of virus-like particles and provides nucleic acid chaperone (NAC) functions during retrotransposition in budding yeast. A subgenomic Ty1 mRNA encodes a truncated Gag protein (p22) that is cleaved by Ty1 protease to form p18. p22/p18 strongly inhibits transposition and can be considered an element-encoded restriction factor. Here, we show that only p22 and its short ...
