Gene regulation is achieved by the control of an operon through induction or repression. Operons are of two types: inducible operons and repressible operons. Inducible operon is a type of operon which gets switched on by a substrate chemical, i.e., an inducer. In a repressible operon, the regulation is done by a chemical substance known p53, also known as TP53 or tumor protein (EC :126.96.36.199) is a gene that codes for a protein that regulates the cell cycle and hence functions as a tumor suppression. It is very important for cells in multicellular organisms to suppress cancer. P53 has been described as "the guardian of the genome", referring to its role in conserving stability ...
Increased morbidity and mortality in recently bereaved spouses (e.g. “widowhood effect”) may be due to alterations in immune function. However, little is known about the impact of bereavement on gene regulation of immune cells. Europe's hub for stem cell research, regenerative medicine and ethics. Features stem cell facts, educational resources, award-winning films, news and FAQ's.
Apr 01, 2009 · An example of a thoroughly studied gene, which has been a model gene for studying mechanisms of transcriptional regulation, is the hemoglobin, beta (HBB)2 gene. The HGMD database contains a total of 490 entries for HBB , of which 234 (48%) are missense/nonsense mutations, 28 (6%) promoter mutations, and 9 (2%) other (3′) regulatory mutations.

Evolution of Gene Regulation. Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes. Gene expression is regulated by the pathways of transcription, translation, and eventual modification of proteins that are formed. Gene expression starts at the DNA level with the transcription of the DNA to form mRNA by creating the complement of the DNA using RNA polymerase. I In addition, KFSE induced gene expression of p21, the apoptosis gene wild-type p53 and the caspase family. At the protein expression level, Bax and Caspase-8 were up-regulated, and the inflammatory marker Nuclear Factor Kappa-B (NF-κB) was down-regulated.
