Introduction

The purpose of this site is to provide verified protocols for biology research. As post-doctoral scholars/junior principle investigators, we have been looking for protocols that we can account for every day. Here, we put all the reliable protocols/reagents we have tested in this site. Unlike those methods described in scientific publications, our methods include great details and useful comments.

We have no intention to commercialize our methods and software. Our goal for this site is simple: make your work more productive and your life much easier, and encourage one another while we are in the same journey.

You can find the methods from the method directory or the search tool on the right.

Feature: please also try our customized, advanced biological method search as well as job search and you may find them cool tools.

SIRT6 links glucose and lipid metabolism

SIRT1, a histone deacetylase, has drawn considerable attention due to its important roles in metabolic regulation and longevity. SIRT1 is induced by fasting and suppressed by feeding. SIRT1 increases glucose production and beta oxidation in liver to meet energy needs during food deprivation. Another member of SIRT family, SIRT6 follows similar expression patterns as SIRT1. The function of SIRT6 in metabolic regulation remains unknown.

Kim and colleagues found SIRT1 can regulate SIRT6 expression in liver. Specifically, SIRT1 functions together with FOXO3a and stimulates SIRT6 transcription during fasting. The activation of SIRT6 directly suppresses gene expression of metabolic enzymes involved in triglyceride synthesis and glycolysis in liver. Deficiency of SIRT6 causes increases of glucose utilization, reduced beta oxidation and as a result, fatty liver. More importantly, Kim et al found the expression of SIRT6 is decreased in human fatty liver samples which indicates SIRT6 may play critical roles in liver steatosis in clinical settings. This study landed in Cell Metabolism of this month. ... Read more highlights.
