Cells of a given type maintain a characteristic cell size to function efficiently in their ecological or organismal context. They achieve this through the regulation of growth rates or by actively sensing size and coupling this signal to cell division. We focus this review on potential size-sensing mechanisms, including geometric, external cue, and titration mechanisms. Mechanisms that titrate ...
A Sigma factor gene which is important in the global regulation of heat shock responses in prokaryotes, rpoH, was isolated from Flexibacter chinesis by PCR, sequenced and compared to the rpoH genes of a variety of other organisms. The rpoH gene was 98% similar to other previously characterized genes. A mutant of rpoH was produced (JR102) which had a reduced growth rate at both low and high temp...
objective(s): atherosclerosis is a chronic immune-inflammatory disease that generally leads to ischemic heart disease. ghrelin has several modulatory effects on cardiovascular system. in this study, we investigated the effect of ghrelin on aortic intima-media thickness, size and the number of adipocyte cells in obese and control mice. materials and methods:this study was conducted on 24 male c5...
Background & Aims: It was aimed to determine the relation between pathological size of renal cell carcinoma on microscopic pathological parameters of radical nephrectomy specimen. Material & Methods: In a retrospective study, we reviewed pathological finding of 76 patients that underwent radical nephrectomy during 2006-2011. We studied the relations between pathological size of tumor with nu...
