摘要

PARP12是聚adp -核糖基聚合酶(PARPs)的一个成员，具有抗病毒功能。然而，其在脂肪细胞中的生理意义尚不清楚。在这里，我们报道了PARP12在产热脂肪细胞中的核心功能。我们发现PARP12在棕色脂肪组织中高度表达，主要定位于线粒体。体外敲低PARP12可降低UCP1的表达。与此同时，PARP12的缺乏减少了脂肪细胞的线粒体呼吸，而PARP12的过表达逆转了这些作用。

PARP12 is required for mitochondrial function maintenance in thermogenic adipocytes.

PARP12 is a member of poly-ADP-ribosyl polymerase (PARPs), which has been characterized for its antiviral function. Yet its physiological implication in adipocytes remains unknown. Here, we report a central function of PARP12 in thermogenic adipocytes. We show that PARP12 is highly expressed in brown adipose tissue and is mainly localized to the mitochondria. Knockdown of PARP12 in vitro reduced UCP1 expression. In parallel, the deficiency of PARP12 reduced mitochondrial respiration in adipocytes, while overexpression of PARP12 reversed these effects.

期刊介绍： Adipocyte recognizes that the adipose tissue is the largest endocrine organ in the body, and explores the link between dysfunctional adipose tissue and the growing number of chronic diseases including diabetes, hypertension, cardiovascular disease and cancer. Historically, the primary function of the adipose tissue was limited to energy storage and thermoregulation. However, a plethora of research over the past 3 decades has recognized the dynamic role of the adipose tissue and its contribution to a variety of physiological processes including reproduction, angiogenesis, apoptosis, inflammation, blood pressure, coagulation, fibrinolysis, immunity and general metabolic homeostasis. The field of Adipose Tissue research has grown tremendously, and Adipocyte is the first international peer-reviewed journal of its kind providing a multi-disciplinary forum for research focusing exclusively on all aspects of adipose tissue physiology and pathophysiology. Adipocyte accepts high-profile submissions in basic, translational and clinical research.
