  Consideration of the rate of product formation at different substrate concentrations and estimation of Michaelis-Menten parameters gives some insight into the possible mechanisms underlying the observed decreases in enzyme activity. Estimates based on two-substrate concentrations lack precision and

  Introduction The structural similarities between puromycin (1, Fig. 1) and the aminoacyl adenyl terminal of aminoacyl–tRNA allow it to terminate the protein synthesis process by causing premature release of a polypeptide from the ribosome [1], [2]. Tremendous progress in the study of puromycin an

  The role of 12/15-LOX plays in autophagy Autophagy is a process by which cellular material is delivered to lysosomal to degrade the damaged organelles and proteins to facilitate nutrient recycling (Towers and Thorburn, 2016). There has been characterized three types of autophagy-macroautophagy, m

  Brain cell reactions Brain cells in common with all metabolic cells must contain chemically active primary compounds which spontaneously initiate and continue cell reactions under normal conditions of temperature and pressure (NTP). These compounds have been identified as monophosphoric and polyp

  Introduction Epinephrine is an endocrine hormone mainly produced by adrenal medulla in response to stress (Tank and Lee Wong, 2015). This catecholamine exerts various major physiological effects, concerning notably the cardiovascular system, the respiratory system and the endocrine system, through

  Unlike in humans, hepatic expression of FGF21 increases in mice consuming KD and is a necessary mediator of the physiologic adaptations to the diet. FGF21 knockout (KO) mice gain, rather than lose weight on the diet [6]. FGF21 also activates BAT in part by increasing SNS drive [3,7]. In addition, th

  NLX-112 (a.k.a. F13640 or befiradol), exhibits nanomolar affinity at 5-HT1A receptors, and, in bx795 to the 5-HT1A receptor agonists listed above, it presents exceptional selectivity and high efficacy at these receptors (Colpaert et al., 2002, Newman-Tancredi et al., 2017). Additionally, it has show

  Regarding the 5-HT1B receptors, they act as terminal receptors and are involved in the presynaptic regulation of the release of 5-HT. But at spinal level these receptors are principally situated post-synaptically (Sari, 2004). The ability of autoreceptors to regulate extracellular levels of 5-HT dur

  Introduction Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone which is mainly secreted from the pineal gland. Melatonin is a highly conserved molecule present not only in vertebrates but also in nonvertebrates such as bacteria, protists, fungi, macroalgae, and plants (Cecon et al., 2017

  TLX may promote survival and prevent apoptosis in NB TSU-68 [12]. Here, we ask whether the survival-promoting effects of TLX are mediated by Apoptosis Signal-regulating Kinase-1 (ASK1, MAP3K5). ASK1 is a member of the Mitogen-Activated Protein (MAP) kinase family and it preferentially activates the
