  Breast Cancer: Although androgens have been considered to be a risk factor in prostate cancer they have been recommended to treat breast cancers. Even before the discovery of SERMs and aromatase inhibitors, steroidal androgens such as medroxyprogesterone and fluoxymesterone were used to treat breast

  Microbe-derived ligands can also activate AHR. Malassezia, a commensal yeast in human skin, can metabolize tryptophan into several AHR activating compounds including FICZ and ICZ [59]. Lactobacillus converts tryptophan into indole-3-aldehyde (IAld), which can activate AHR and promote IL-22 productio

  A similar circuit between pyramidal neurons and SST interneurons is also prevalent in layers 2/3 of the cortex. The synapses onto SST interneurons, however, are functionally weak, raising questions about their computational power. In the first set of experiments, Urban-Ciecko et al. (2018) show that

  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

  2024-06-21

  

  Phagosomes acquire some hydrolases early during their journey from the cell surface to lysosomes. An example for such hydrolase is cathepsin H which is most concentrated in the early phagosome at a pH of approximately 6.3 (Claus et al., 1998), the pH optimum of enzyme activity (Schwartz and Barrett,

  Introduction: the DNA damage response — important implications for tumour development and treatment Cells are invariably challenged by tens of thousands of lesions inflicted on their DNA everyday (Lindhal, 1993). This DNA damage can be caused exogenously by exposure to different types of radiation

  There is a delicate balance between ROS generation and scavenging by the protective antioxidant defenses in the cell. Antioxidant systems present in the PAI-039 include enzymes like superoxide dismutase (SOD), catalases, glutathione peroxidases (GPxs) and peroxiredoxins (PRxs) (Fig. 3) [38]. SODs a
