Key result
Fas mutation in mice prevented high-fat diet-induced obesity, improved glucose tolerance, and promoted white adipose tissue browning by increasing IL-4 and IL-10 expression.
Why the study?
Fas mutant MRL/lpr mice exhibit a significantly leaner phenotype than wild type MRL/MpJ mice, prompting investigation into their adipose tissue inflammatory cell population and beige fat activity.
Does Fas mutation prevent high-fat diet-induced obesity and promote white adipose tissue browning in mice?
Does Fas mutation prevent high-fat diet-induced obesity and promote white adipose tissue browning in mice?
p-value: p=<0.05
Fas mutation in mice confers resistance to high-fat diet-induced obesity by increasing IL-4 and IL-10 levels, promoting M2 macrophage polarization, and enhancing white adipose tissue browning.

Choi et al. (2020) studied Obesity. Fas mutation vs. Wild type (MRL/MpJ) was evaluated on Body weight, fat mass, and thermogenic protein expression (p=<0.05). Fas mutation in mice prevented high-fat diet-induced obesity, improved glucose tolerance, and promoted white adipose tissue browning by increasing IL-4 and IL-10 expression.
