Journal ArticleDOI
Calcium and ROS: A mutual interplay.
TL;DR: Increasing evidence suggests a mutual interplay between calcium and ROS signaling systems which seems to have important implications for fine tuning cellular signaling networks.
Journal ArticleDOI
H(2)S and HS(-) donor NaHS releases nitric oxide from nitrosothiols, metal nitrosyl complex, brain homogenate and murine L1210 leukaemia cells.
Karol Ondrias,Andrej Staško,Sona Cacanyiova,Zdena Sulova,Olga Krizanova,Frantisek Kristek,Lubica Malekova,Vladimir Knezl,Albert Breier +8 more
TL;DR: NaHS released NO from nitrosothiols, namely from GSNO, S-nitroso-N-acetyl-dl-penicillamine (SNAP), from metal nitrosyl complex nitroprusside (SNP) and from rat brain homogenate and murine L1210 leukaemia cells and it is assumed that HS−, rather than H2S, is responsible for the NO-releasing effect.
Journal ArticleDOI
Stress, catecholaminergic system and cancer.
TL;DR: The current knowledge about catecholamines as important stress hormones in tumorigenesis is summarized and the use of β-blockers as the potential therapeutic agents are discussed.
Journal ArticleDOI
Athymic nude mice as an experimental model for cancer treatment.
TL;DR: Athymic nude mice, a murine strain bearing spontaneous deletion in the Foxn1 gene that causes deteriorated or absent thymus, represent a widely used model in cancer research having long lasting history as a tool for preclinical testing of drugs.
Journal ArticleDOI
Gene expression of phenylethanolamine N-methyltransferase in corticotropin-releasing hormone knockout mice during stress exposure.
Richard Kvetnansky,L. Kubovcakova,Andrej Tillinger,Lucia Micutkova,Olga Krizanova,Esther L. Sabban +5 more
TL;DR: Reduced plasma epinephrine and corticosterone levels and adrenal medullary EGR-1 protein levels in CRH knockout versus WT mice during stress indicate that the HPA axis plays a crucial role in regulation of the PNMT gene expression in these organs.
