The basal-like carcinoma is a recently proposed subtype of breast cancer defined by its gene expression and protein expression profile. [1]Breast cancer can be divided into five molecular subtypes, including luminal subtype A, luminal subtype B, normal breast-like subtype, HER-2 overexpression subtype, and basal-like subtype. [2]
Aldolase B is a homotetrameric enzyme, composed of four subunits with molecular weights of 36 kDa with local 222 symmetry. Each subunit has a molecular weight of 36 kDa and contains an eight-stranded α/β barrel, which encloses lysine 229 (the Schiff-base forming amino acid that is key for catalysis).
Fructose-1-phosphate is metabolized by aldolase B into dihydroxyacetone phosphate and glyceraldehyde. HFI is caused by a deficiency of aldolase B. [5] A deficiency of aldolase B results in an accumulation of fructose-1-phosphate, and trapping of phosphate (fructokinase requires adenosine triphosphate (ATP)). The downstream effects of this ...
Some defects in aldolase B cause hereditary fructose intolerance. The metabolism of free fructose in liver exploits the ability of aldolase B to use fructose 1-phosphate as a substrate . [ 6 ] Archaeal fructose-bisphosphate aldolase/phosphatase is presumably involved in gluconeogenesis because its product is fructose 6-phosphate.
Absolute risk of cancers in BRCA1 or BRCA2 mutation. [4]A number of genes are associated with HBOC. [5] The most common of the known causes of HBOC are: BRCA mutations: [5] Harmful mutations in the BRCA1 and BRCA2 genes can produce very high rates of breast and ovarian cancer, as well as increased rates of other cancers.
The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
This is a list of major breast cancer cell lines that are primarily used in breast cancer research. [Notes 1] List of cell lines. Cell line Primary tumor
Molecular classification of breast cancer from mRNA expression profiles. DNA microarrays have compared normal cells to breast cancer cells and found differences in the expression of hundreds of genes. Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that ...
