  2023-09-09

  

  Telomerase action at the telomere is highly regulated; it preferentially elongates the shortest telomeres, and recruitment of the enzyme complex to the telomere occurs in mid-S phase of the cell cycle (Bianchi and Shore, 2007, Britt-Compton et al., 2009, Teixeira et al., 2004, Hemann et al., 2001, T

  Because 5α-R2 gene is positively regulated by T and in the prostate gland (Torres et al., 2003), and our BPA-treated rats showed decreased circulating T and probably intraprostatic androgen levels, it might be responsible for the decrease of 5α-R2 expression. However, in a previous work using castra

  Thalidomide is now a well known antiangiogenic agent. This property of thalidomide is being extensively researched upon, for its significant utility in the treatment of various malignant tumors. Studies show that thalidomide efficaciously inhibits various pro-angiogenic factors such as tumor necrosi

  Introduction Lipoxygenases (LOXs) are key enzymes that catalyze the polyunsaturated fatty acids (PUFAs) such as arachidic BX795 (AA), linoleic acid (LA) and others unsaturated fatty acids (Brash, 1999). LOXs are expressed in immune, neural, epithelial, tumor cells and other cells (Claesson, 2009).

  AHR expression in cancer Perhaps the earliest indicator that the AHR might play an ongoing role in tumorigenesis, independent of its role in generating mutations, was the demonstration that non-genotoxic 2,3,7,8-tetrachlorodibenzo(p)dioxin (TCDD) is a carcinogen in animals and humans [7]. Althoug

  6-hydroxydopamine (6-OHDA) is a selective catecholaminergic neurotoxin mainly used to generate lesions in the nigrostriatal pathway in rats (Ungerstedt, 1968). The most common use of 6-OHDA is via unilateral injection into the rat medial forebrain bundle (MFB). DA depletion, nigral DA cell loss, and

  As noted earlier, the PfkB family of carbohydrate kinases can phosphorylate the hydroxymethyl group of a wide variety of sugar moieties [1], [3]. Recent searches of the Swiss-Prot database with the two conserved sequence motifs found in these proteins (Accession nos. PS00583 and PS00584) identified

  The cytochrome P450 enzyme 17α-hydroxylase/17,20-lyase (P450) is involved in the production of the C containing androgen precursors from the C containing steroids such as the pregnanes and progestins (). Steroids such as androstenedione (AD) and dehydroepiandrosterone (DHEA) are therefore synthesi

  Many metalloenzyme inhibitors consist of two chemical components: the MBG, the portion of the inhibitor designed to bind to the metal, and the scaffold, the portion of the inhibitor recognized by the amino Okadaic acid residues that form the substrate-binding site of the metalloenzyme. The MGB is o

  Introduction The principal pathways of adrenal and gonadal steroidogenesis have been known for over 50 years (reviewed by Miller and Auchus, 2011). Cholesterol is first converted to pregnenolone via three reactions, 20-hydroxylation, 22-hydroxylation and scission of the 20,22 carbon–carbon bond,
