Helix-loop-helix proteins: regulators of transcription in eucaryotic organisms.
The helix-loop-helix (HLH) family of transcriptional regulatory proteins are key players in a wide array of developmental processes. Over 240 HLH proteins have been identified to date in organisms ranging from the yeast Saccharomyces cerevisiae to humans (6). Studies in Xenopus laevis, Drosophila melanogaster, and mice have convincingly demonstrated that HLH proteins are intimately involved in ...
متن کاملthe most important demotivating factors among efl teachers in private english language institutes in mashhad
just as motivation is important in sla research, demotivation constitutes an important factor, too. there are many studies done on demotivation and burnout of teachers. many of these studies have been conducted on one or two aspects of english instruction. consequently, there are few studies which have been done on more than two aspects of english teaching. the aim of this study is to find out ...
The molecular perspective: the ras oncogene.
together when to divide, when to differentiate, and when to die. Often, cells communicate with one another by delivering protein messages. These proteins—hormones, growth factors, chemokines, etc.—are far too large to enter the receiving cell, so an elaborate mechanism of signal transduction has been developed, to transmit messages from the cell surface into the cell nucleus, where the topic of...
متن کاملCalcium an Important Food Element
The absorption of dietary calcium (Ca) may in part be determined by the formation in the intestinal lumen of soluble Ca complexes and insoluble Ca salts. This study was undertaken to test the assumption that ionic Ca concentration (Ca2+) is the only species of Ca that is available for absorption. Bidirectional steady-state Ca fluxes were measured in vitro under short-circuit conditions across s...
متن کاملRAS proto-oncogene in medullary thyroid carcinoma.
Medullary thyroid carcinoma (MTC) is a rare malignancy originating from the calcitonin-secreting parafollicular thyroid C cells. Approximately 75% of cases are sporadic. Rearranged during transfection (RET) proto-oncogene plays a crucial role in MTC development. Besides RET, other oncogenes commonly involved in the pathogenesis of human cancers have also been investigated in MTC. The family of ...
