Biology of Cachexia [PDF]

JNCI Journal of the National Cancer Institute, 1997
About half of all cancer patients show a syndrome of cachexia, characterized by loss of adipose tissue and skeletal muscle mass. Such patients have a decreased survival time, compared with the survival time among patients without weight loss, and loss of total body protein leads to substantial impairment of respiratory muscle function.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Systemic inflammation and oxidative stress in bronchiectasis-associated sarcopenia

ERJ Open Research
Introduction Sarcopenia has recently been associated with bronchiectasis. We hypothesised that inflammation and oxidative stress are elevated in both systemic and muscle compartments in patients with bronchiectasis-associated sarcopenia, even in the ...

Cancer cachexia: Focus on cachexia factors and inter-organ communication

Chinese Medical Journal
. Cancer cachexia is a multi-organ syndrome and closely related to changes in signal communication between organs, which is mediated by cancer cachexia factors. Cancer cachexia factors, being the general name of inflammatory factors, circulating proteins,

Reversing Cachexia [PDF]

Cell, 2010
Muscle atrophy (cachexia) in cancer patients is a life-threatening condition for which therapeutic options are limited. Zhou et al. (2010) now identify a new target for treating cachexia, the activin type-2 receptor (ActRIIB). In several mouse models of cachexia, the authors reversed wasting of skeletal and cardiac muscle and increased life span by ...
