Chalone Rangers: The Tissue-Specific Mitotic Inhibitors You Never Knew You Needed
Chalones are the unsung heroes of cellular crowd control. These tissue-specific, water-soluble substances are like the bouncers of your body, standing at the gates of mitosis with their arms crossed, saying, “Not tonight, buddy.” They’re the biochemical equivalent of that one friend who knows when to call it a night before things get out of…

Pelger–Huët anomaly, congenital and acquired, also pince-nez, laminopathy and a little ebola
Pelger–HuĂ«t anomaly is a blood laminopathy associated with the lamin B receptor, wherein several types of white blood cells (neutrophils and eosinophils) have nuclei with unusual shape (being bilobed, peanut or dumbbell-shaped instead of the normal trilobed shape) and unusual structure (coarse and lumpy). It is a genetic disorder with an autosomal dominant inheritance pattern. Heterozygotes are clinically normal, although their neutrophils may be mistaken for immature cells which may cause…

p-Phenylenediamine (PPD) is a derivative of aniline used in kevlar, hair dye and henna substitutions among other things, the derivatives of which are used in antiozonants among other horrors
p-Phenylenediamine (PPD) is an organic compound with the formula C6H4(NH2)2. This derivative of aniline is a white solid, but samples can darken due to air oxidation.It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes and is occasionally used as a substitute for henna. Production PPD is produced via three routes. Most commonly, 4-nitrochlorobenzene is treated…

p300-CBP coactivator family – clinical significance
Mutations in CBP, and to a lesser extent p300, are the cause of Rubinstein-Taybi Syndrome, which is characterized by severe mental retardation. These mutations result in the loss of one copy of the gene in each cell, which reduces the amount of CBP or p300 protein by half. Some mutations lead to the production of a very…

Histone acetyltransferase p300
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 (where E1A = adenovirus early region 1A) also known as EP300 or p300 is an enzyme that, in humans, is encoded by the EP300 gene. It functions as histone acetyltransferase that regulates transcription of genes via chromatin remodeling by allowing histone proteins to wrap DNA less tightly. This enzyme plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions…

CBP has been shown to play a role in every stage of tumor development
Due to its critical role in regulation of cell proliferation, growth, migration and apoptosis, it is considered to be an oncogene, or tumor suppressor. Contrarily To date, increased CBP activity has been implicated in a variety of different malignancies including breast cancer, lung cancer, prostate cancer, colorectal cancer, acute leukemias, head and neck cancer, and many others. According to the Catalog…

Interleukin-2-recptor alpha chain (IL2RA also called CD25) is the human protein encoded by the IL2RA gene.
The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolysis. Alternately-spliced…
