  2023-11-17

  

  The difficulty of characterizing nAChRs in the central nervous system is also exemplified by early observations that nicotine caused no detectable effect when applied on a brain slice and it is only with the focal and high time resolution of more recent experiments that the effects of nicotinic neur

  Experimental procedure Funding The present study was supported by the Grant Russian Foundation for basic research (project no. 16-04-01517). Introduction 5-HT, a monoaminergic neurotransmitter, is synthesised from l-tryptophan catalysed by the enzymes tryptophan hydroxylase (Tph) and aroma

  Regarding androgens, it is known that they are also essential for reproductive success (Walters et al., 2010). At the molecular level, their effects are produced mainly by dihydrotestosterone (DHT), arising from the conversion of testosterone by the enzyme 3-oxo-5-alpha-steroid-4-dehydrogenase (enco

  2023-11-16

  

  How does the ATM-to-ATR switch occur at DSBs? The progressive attenuation of ATM activation could be attributed to the loss of DNA structures that activate ATM, or to the generation of DNA structures that interfere with ATM activation. Our finding that SSOs do not directly affect the binding of puri

  Enhanced arginase activity and the resultant decreases in L-arginine levels can also impair T cell mediated immune function and allow tumor growth by limiting the supply of L-arginine needed for the formation of cytotoxic levels of NO by iNOS [10]. Increased arginase expression/activity may also lim

  2023-11-16

  

  Autophagy and apoptosis have a very complex relationship, and the precise mechanism remains to be determined. At present, a large amount of research has confirmed that autophagy can protect the cell from apoptosis in special conditions such as nutrient deficiency or growth factors deprivation; the e

  2023-11-16

  

  The transcription factor activator protein-1 (AP-1) is a redox-sensitive transcription factor whose activity is controlled by agents that perturb intracellular thiol concentrations [10,11]. AP-1 is mainly composed of Jun, Fos, and ATF protein dimers [12,13]. AP-1 mediates the regulation of numerous

  On the contrary, Birrel and colleagues observed divergent proliferative responses to androgens in different BC cell lines: DHT and mibolerone were found to inhibit the T47-D and ZR-75-1 Anidulafungin growth, while the proliferation of MCF-7 cells was increased by both the androgens [53].

  In another study, Yerra and Kumar (2016) used streptozotocin to induce diabetic neuropathy in rats. Mechanical/thermal hyperalgesia, motor/sensory nerve conduction velocities (MNCV and SNCV) and sciatic nerve blood flow (NBF) were evaluated. In vitro studies of Neuro2a (N2A) cell culture were perfor

  Calcium entry through postsynaptic NMDARs activates intracellular signaling cascades including Ca2+/calmodulin (CaM)-dependent protein kinase II (CaMKII) and calcineurin. The spatiotemporal abundance of this Ca2+/CaM complex determines the direction of synaptic plasticity, resulting in LTP (Malinow
