Alcohol metabolite acetic acid activates BK channels in a pH-dependent manner and decreases calcium oscillations and exocytosis of secretory granules in rat pituitary GH3 cells

Shaidullov I.; Ermakova E.; Gaifullina A.; Mosshammer A.; Yakovlev A.; Weiger T.M.; Hermann A.; Sitdikova G. (2021)

Acetaldehyde and acetic acid/acetate, the active metabolites of alcohol (ethanol, EtOH), generate actions of their own ranging from behavioral, physiological, to pathological/cancerogenic effects. EtOH and acetaldehyde ...
Gasotransmitters: Physiology and pathophysiology

Hermann A.; Sitdikova G.; Weiger T. (2013)

© Springer-Verlag Berlin Heidelberg 2012. All rights are reserved. Since the epochal discovery of the radical and highly toxic gas nitric oxide (NO) as a signaling molecule, two other no less toxic gases - carbon monoxide ...
Homocysteine augments BK channel activity and decreases exocytosis of secretory granules in rat GH3 cells

Gaifullina A.; Yakovlev A.; Mustafina A.; Weiger T.; Hermann A.; Sitdikova G. (2016)

© 2016 Federation of European Biochemical SocietiesIn this study, we investigated the effects of L-homocysteine (Hcy) on maxi calcium-activated potassium (BK) channels and on exocytosis of secretory granules in GH3 rat ...

Hydrogen sulfide alleviates anxiety, motor, and cognitive dysfunctions in rats with maternal hyperhomocysteinemia via mitigation of oxidative stress

Yakovleva O.; Bogatova K.; Mukhtarova R.; Yakovlev A.; Shakhmatova V.; Gerasimova E.; Ziyatdinova G.; Hermann A.; Sitdikova G. (2020)

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Hydrogen sulfide (H2S) is endogenously produced from sulfur containing amino acids, including homocysteine and exerts neuroprotective effects. An increase of ...
Hydrogen sulfide increases calcium-activated potassium (BK) channel activity of rat pituitary tumor cells

Sitdikova G.; Weiger T.; Hermann A. (2010)

Hydrogen sulfide (H2S) is the third gasotransmitter found to be produced endogenously in living cells to exert physiological functions. Large conductance (maxi) calcium-activated potassium channels (BK), which play an ...
Hydrogen sulfide induces hyperpolarization and decreases the exocytosis of secretory granules of rat GH3 pituitary tumor cells

Mustafina A.; Yakovlev A.; Gaifullina A.; Weiger T.; Hermann A.; Sitdikova G. (2015)

© 2015 Elsevier Inc. All rights reserved. The aim of the present study was to evaluate the effects of hydrogen sulfide (H<inf>2</inf>S) on the membrane potential, action potential discharge and exocytosis of secretory ...
Modulated by gasotransmitters: BK channels

Hermann A.; Sitdikova G.; Weiger T. (2012)

© Springer-Verlag Berlin Heidelberg 2012. All rights are reserved. Calcium-activated potassium BK channels interconnect cellular activity, calcium signaling, and cell metabolism. Major virtues of these channels are their ...

Receptor mechanisms mediating the pro-nociceptive action of hydrogen sulfide in rat trigeminal neurons and meningeal afferents

Koroleva K.; Mustafina A.; Yakovlev A.; Hermann A.; Giniatullin R.; Sitdikova G. (2017)

© 2017 Koroleva, Mustafina, Yakovlev, Hermann, Giniatullin and Sitdikova. Hydrogen sulfide (H 2 S), a well-established member of the gasotransmitter family, is involved in a variety of physiological functions, including ...
Short chain fatty acids and colon motility in a mouse model of irritable bowel syndrome

Shaidullov I.F.; Sorokina D.M.; Sitdikov F.G.; Hermann A.; Abdulkhakov S.R.; Sitdikova G.F. (2021)

Background: Irritable bowel syndrome (IBS) is defined as a multifactorial disorder associated with visceral hypersensitivity, altered gut motility and dysfunction of the brain-gut axis. Gut microbiota and its metabolites ...
