Development of catecholamine and cortisol stress responses in zebrafish. [PDF]
, 2014 Both adrenal catecholamines and steroids are known to be involved in the stress response, immune function, blood pressure and energy homeostasis. The response to stress is characterized by the activation of the hypothalamus-pituitary-adrenal (HPA) axis ...

Adipocytes cause leukemia cell resistance to daunorubicin via oxidative stress response. [PDF]
, 2016 Adipocytes promote cancer progression and impair treatment, and have been shown to protect acute lymphoblastic leukemia (ALL) cells from chemotherapies. Here we investigate whether this protection is mediated by changes in oxidative stress.

Stress Responses in Mycobacteria [PDF]
IUBMB Life (International Union of Biochemistry and Molecular Biology: Life), 2005 Mycobacterium tuberculosis is a successful pathogen that overcomes numerous challenges presented by the immune system of the host. This bacterium usually establishes a chronic infection in the host where it may silently persist inside a granuloma until, a failure in host defenses, leads to manifestation of the disease.

Genes and Environment, 2017 Apurinic/apyrimidinic (AP) sites are one of the most frequent DNA lesions. AP sites inhibit transcription and DNA replication, and induce cell death. AP endonucleases are key enzymes in AP site repair. Several types of AP endonucleases have been reported,

Disordered eating behaviour is associated with blunted cortisol and cardiovascular reactions to acute psychological stress [PDF]
, 2012 Research suggests a potential dysregulation of the stress response in individuals with bulimia nervosa. This study measured both cardiovascular and cortisol reactions to a standardised laboratory stress task in individuals identified as showing ...

The Aging Stress Response [PDF]
Molecular Cell, 2010 Aging is the outcome of a balance between damage and repair. The rate of aging and the appearance of age-related pathology are modulated by stress response and repair pathways that gradually decline, including the proteostasis and DNA damage repair networks and mitochondrial respiratory metabolism.

Prophages and Growth Dynamics Confound Experimental Results with Antibiotic-Tolerant Persister Cells
mBio, 2017 Bacterial persisters are phenotypic variants that survive antibiotic treatment in a dormant state and can be formed by multiple pathways. We recently proposed that the second messenger (p)ppGpp drives Escherichia coli persister formation through protease
