Starvation induced cholesterogenesis in hepatic and extra hepatic tissues of climbing perch, Anabas testudineus (Bloch)‎

Abstract EN

Cholesterol is a structural lipid, which may be differentially utilized or synthesized in response to stress or during insulin deficient states such as starvation.

In the present investigation we estimated the levels of cholesterol in Anabas testudineus, which was subjected to brief (15 days) and prolonged fasting (60 days).

Tissues such as liver, kidney, brain, accessory respiratory organ, pectoral and lateral line muscle were selected for the study.

Cholesterol content was estimated by the Crawford method (1958).

Both the starvation regimes showed a significant increase in cholesterol levels in almost all the tissues, but for liver, which strangely showed an insignificant decline during the short-term starvation.

This overall upsurge in cholesterol levels observed in all extra hepatic tissues may be attributed to the synthesis of stress hormones such as glucocorticoids, which may promote gluconeogenesis and adrenocorticoids, which may help the animal to combat the stressful condition of starvation.

Anabas adapted well to starvation stress and survived all throughout the experimental period.
