Obesity and related metabolic diseases, such as type 2 diabetes, hypertension and hyperlipidemia are an increasingly prevalent medical and social problem in developed and developing countries. These conditions are associated with increased risk of cardiovascular disease, the leading cause of death. Therefore, it is important to understand the molecular basis underlying obesity and related metabolic diseases in order to develop effective preventive and therapeutic approaches against these conditions. Recently, a family of proteins structurally similar to the angiogenic-regulating factors known as angiopoietins was identified and designated 'angiopoietin-like proteins' (ANGPTLs). Encoded by seven genes, ANGPTL1-7 all possess an N-terminal coiled-coil domain and a C-terminal fibrinogen-like domain, both characteristic of angiopoietins. ANGPTLs do not bind to either the angiopoietin receptor Tie2 or the related protein Tie1, indicating that these ligands function differently from angiopoietins. Like angiopoietins, some ANGPTLs potently regulate angiogenesis, but ANGPTL3, -4 and ANGPTL6/angiopoietin-related growth factor (AGF) directly regulate lipid, glucose and energy metabolism independent of angiogenic effects. Recently, we found that ANGPTL2 is a key adipocyte-derived inflammatory mediator that links obesity to systemic insulin resistance. In this minireview, we focus on the roles of ANGPTL2 and ANGPTL6/AGF in obesity and related metabolic diseases, and discuss the possibility that both could function as molecular targets for the prevention and treatment of obesity and metabolic diseases.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women. The abnormalities of endocrine and intra-ovarian paracrine interactions may change the microenvironment for oocyte development during the folliculogenesis process and reduce the developmental competence of oocytes in PCOS patients who are suffering from anovulatory infertility and pregnancy loss. In this microenvironment, the cross talk between an oocyte and the surrounding cumulus cells (CCs) is critical for achieving oocyte competence. The aim of our study was to investigate the gene expression profiles of CCs obtained from PCOS patients undergoing IVF cycles in terms of oocyte maturation by using human Genome U133 Plus 2.0 microarrays. A total of 59 genes were differentially expressed in two CC groups. Most of these genes were identified to be involved in one or more of the following pathways: receptor interactions, calcium signaling, metabolism and biosynthesis, focal adhesion, melanogenesis, leukocyte transendothelial migration, Wnt signaling, and type 2 diabetes mellitus. According to the different expression levels in the microarrays and their putative functions, six differentially expressed genes (LHCGR, ANGPTL1, TNIK, GRIN2A, SFRP4, and SOCS3) were selected and analyzed by quantitative RT-PCR (qRT-PCR). The qRT-PCR results were consistent with the microarray data. Moreover, the molecular signatures (LHCGR, TNIK, and SOCS3) were associated with developmental potential from embryo to blastocyst stage and were proposed as biomarkers of embryo viability in PCOS patients. Our results may be clinically important as they offer a new potential strategy for competent oocyte/embryo selection in PCOS patients.
