cAMP regulates gastrin gene expression

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1995
Gastrin is one of the most potent regulators of acid secretion and gastrointestinal cell growth. A variety of signals regulate gastrin release from the antral G cell. However, whether these secretagogues also stimulate gastrin gene expression has not been established.

Regulation of metallothionein gene expression

2000
The rapid and robust induction of metallothioneins (MT)-I and II by a variety of inducers that include heavy toxic metals, reactive oxygen species, and different types of stress provide a useful system to study the molecular mechanisms of this unique induction process.

Ploidy Regulation of Gene Expression

Science, 1999
Microarray-based gene expression analysis identified genes showing ploidy-dependent expression in isogenic Saccharomyces cerevisiae strains that varied in ploidy from haploid to tetraploid. These genes were induced or repressed in proportion to the number of chromosome sets, regardless of the mating type.

Regulation of Neuronal Gene Expression

Naturwissenschaften, 1999
Humans as multicellular organisms contain a variety of different cell types where each cell population must fulfill a distinct function in the interest of the whole organism. The molecular basis for the variations in morphology, biochemistry, molecular biology, and function of the various cell types is the cell-type specific expression of genes.

Hypoxia Regulates Osteoblast Gene Expression

Journal of Surgical Research, 2001
Vascular disruption secondary to fracture creates a hypoxic gradient of injury wherein the oxygen tension at the center of the wound is very low. In vivo this hypoxic microenvironment stimulates the expression of a variety of cytokines from inflammatory cells, fibroblasts, endothelial cells, and osteoblasts.

Regulation of GATA1 Gene Expression

Journal of Biochemistry, 2007
GATA1 is one of the most fascinating transcription factors for biologists. It regulates many haematopoietic genes and interacts with a number of other transcription factors. Its functions are mostly conserved among vertebrates. Upon disruption of the GATA1 gene, mice show a drastic bloodless phenotype.

Regulation of ABO gene expression

Legal Medicine, 2005
The ABO blood group system is important in blood transfusions and in identifying individuals during criminal investigations. Two carbohydrate antigens, the A and B antigens, and their antibodies constitute this system. Although biochemical and molecular genetic studies have demonstrated the molecular basis of the histo-blood group ABO system, some ...

Short Peptides Regulate Gene Expression

Bulletin of Experimental Biology and Medicine, 2016
Short peptides constitute the system of signal molecules regulating the functions of the organism at the molecular, genetic, subcellular, cellular, and tissue levels. One short peptide can regulate dozens of genes, but the molecular mechanism of this process remains unclear.

Regulation of Adenovirus Gene Expression

1982
Adenoviruses were discovered in 1953 and constitute a family of viruses originally isolated from the respiratory tract of man and other animals. The adenovirus family has been subdivided into two genera, mastadenovirus and aviadenovirus, referring to the virus isolated from mammalian and avian hosts, respectively.

Androgen Regulation of Gene Expression

2010
The biological action of androgenic male sex steroid hormones in prostate tissue is mediated by the androgen receptor, a nuclear transcription factor. The transcriptional program of androgenic signaling in the prostate consists of thousands of gene targets whose products play a role in almost all cellular functions, including cellular proliferation ...
