  • α-Tubulin is a cytoskeletal protein and constituent of microtubules, a cytoskeletal assembly that has roles in a variety of cellular processes, including cell motility, division, differentiation, and intracellular transport.{57121} α-Tubulin is highly conserved in eukaryotes and expressed in a cell- and isotype-specific manner.{57122} There are eight human α-tubulin isotypes that consist of an N-terminal domain, which binds GTP and is required for microtubule self-assembly, and a variable C-terminal tail, which contains interaction sites for microtubule-associated proteins (MAPs) and is subject to a variety of post-translational modifications that regulate microtubule function and stability.{57123,57124,57121,57125} Cayman’s α-Tubulin Monoclonal Antibody can be used for immunocytochemistry (ICC) and Western blot (WB) applications. The antibody recognizes α-tubulin at approximately 50 kDa.

  • β-Catenin is a central component of the cadherin cell adhesion complex and plays an essential role in neural development in the Wingless/Wnt signaling pathway.{14334,14336} The role of β-catenin in these processes is thought to be regulated by the sequential phosphorylation of Ser29, Ser33, Ser37, and Thr41 by glycogen synthase kinase 3β (GSK3β).{14335} This hyperphosphorylation promotes the ubiquitylation and targeted destruction of β-catenin. Mutations in components of this phosphorylation-regulated process that prevent β-catenin hyperphosphorylation by GSK3β are strongly associated with cancers.{14335,14336,14337}

  • β-Hydroxybutyrate (β-HB; 3-hydroxybutyric acid) is a “ketone body” which is produced in the liver, mainly from the oxidation of fatty acids, and is exported to peripheral tissues for use as an energy source. The term ‘ketone body’ refers to three molecules, acetoacetate, β-HB, and acetone. β-HB and acetoacetate transport energy from the liver to the other tissues and acetone is generated by spontaneous decarboxylation of acetoacetate.{17093} The presence of ketosis may be normal or pathologic. Normally ketosis can indicate that lipid metabolism has been activated and the pathway of lipid degradation is intact. Normal ketosis is prevalent in many circumstances such as during fasting, after prolonged exercise or after a high fat diet. Pathological causes of ketosis include multiple organ failure, diabetes, childhood hypoglycemia, corticosteroid or growth hormone deficiency, intoxication with alcohol or salicylates and several inborn errors of metabolism.{17094} In acutely ill patients, these ketone bodies can accumulate in the body to cause ketoacidosis, which leads to the potentially life threatening condition known as metabolic acidosis.{17125} The presence and degree of ketosis can be determined by measuring blood levels of β-HB. Ordinarily, β-HB accounts for approximately 75% of the ketone bodies in serum.{17126,17127,17095} Measurement of β-HB provides a reliable index of the level of ketoacidosis, including the detection of subclinical ketosis.{17096,17097,17128} In diabetics, β-HB measurements (and blood glucose) can be used for the assessment of the severity of diabetic coma and is essential for the exclusion of hyperosmolar non-ketotic diabetic coma. The measurement of β-HB is also used to monitor insulin requirements, based on existing hyperketonemia.{17098} β-HB has more recently been evaluated for use in neurodegenerative diseases and inhibition of adipocyte lipolysis.{17099,17100,17101,17102,17103} Cayman’s β-HB (Ketone Body) Assay Kit provides a simple, reproducible, and sensitive tool for measuring β-HB levels in plasma, serum, urine, cell lysates, or tissue homogenates. The method for β-HB determination is based upon the oxidation of D-3-Hydroxybutyrate to acetoacetate by the enzyme 3-hydroxybutyrate dehydrogenase.{17104} Concomitant with this oxidation, the cofactor NAD+ is reduced to NADH. In the presence of diaphorase, NADH reacts with the colorimetric detector WST-1 to produce a formazan dye with an absorbance maximum at 445-455 nm. The absorbance of the dye is directly proportional to the β-HB concentration.

The method for β-HB determination is based upon the oxidation of D-3-Hydroxybutyrate to acetoacetate by the enzyme 3-hydroxybutyrate dehydrogenase. Concomitant with this oxidation, the cofactor NAD+ is reduced to NADH. NADH reacts with the fluorometric developer to yield a highly fluorescent product which can be analyzed with an excitation wavelength of 530-540 nm and an emission wavelength of 585-595 nm. The fluorescence is directly proportional to the β-HB concentration.

  • β-Nicotyrine is an alkaloid metabolite of nicotine as well as a major product of its pyrolysis.{26726,26727} It binds comparably to two cytochrome P450 (CYP) isoforms, CYP2A6 and CYP2A13 (Kis = 7.5 and 5.6 µM, respectively), which are prominently involved in the metabolism of xenobiotics in the airways.{26724} However, β-nicotyrine appears to more effectively inactivate CYP2A6, leaving only 49% activity after a 10 minute exposure with 20 µM β-nicotyrine, as opposed to 87% remaining activity for CYP2A13 treated identically.{26722} Presumably through this effect, β-nicotyrine inhibits DNA strand breaks induced by the genotoxic tobacco metabolite (4-(methylnitrosamino)-1-(2-pyridyl)-1-butanone), which is bioactivated by CYP2A isoforms.{26723}
