Stress proteins of Clostridium perfringens type A immunoreact with antiserum from rabbits infected with gas gangrene

19.02.2004 | Norma Heredia, Elva Aréchiga, Ronald Labbé, Santos García, International Microbiology, 2004

Various stressors were used to induce stress proteins in Clostridium perfringens. Cultures of C. perfringens FD-1041 were subjected to cold shock (28°C for 1h), acid shock (pH4.5 for 30min), or heat shock (50°C for 30min). Cells were lysed and protein samples were analyzed by immunoblotting ...

Learning from yeasts: intracellular sensing of stress conditions

19.02.2004 | Mariano Gacto, Teresa Soto, Jero Vicente-Soler, Tomás G. Villa, José Cansado, International Microbiology, 2004

One intriguing challenge in modern biology is to understand how cells respond to, and distinguish between different stressing stimuli. Evidence accumulated in recent years indicates that a network of signaling pathways extends from the plasma membrane to the very core of the cell nucleus to ...

Trehalose accumulation induced during the oxidative stress response is independent of TPS1 mRNA levels in Candida albicans

01.06.2003 | Óscar Zaragoza, Pilar González-Párraga, Yolanda Pedreño, Francisco J. Alvarez-Peral, Juan-Carlos Argüelles, International Microbiology, 2003

Growing cells of the Candida albicans trehalose-deficient mutant tps1/tps1 were extremely sensitive to severe oxidative stress exposure (H2O2). However, their viability was not affected after saline stress or heat-shock treatments, being roughly equivalent to that of the parental strain. In ...

An mRNA-specific tRNAi carrier eIF2A plays a pivotal role in cell proliferation under stress conditions: stress-resistant translation of c-Src mRNA is mediated by eIF2A

11.10.1995 | M. Ahmad Chaudhry; Michael Weinfeld, Nucleic Acids Research, 1995

c-Src, a non-receptor protein tyrosine kinase, activates NF-B and STAT3, which in turn triggers the transcription of anti-apoptosis- and cell cycle-related genes. c-Src protein regulates cell proliferation, cell motility and programmed cell death. And the elevated level of activated c-Src protein ...
