Description
Dietary proteins have profound effects on lipid metabolism but the mechanism remains to be elucidated. In the present study, we examined the temporal impact of dietary proteins in isoenergetic high fat diets on lipid metabolism of C57BL/6J mice.

Description
This study aimed at investigating the impact of chronic ingestion of sebacic acid (SA), a 10 carbons medium-chain dicarboxylic acid, on glycemic control in a mouse model of type 2 diabetes (db/db mice). Three groups of 15 mice were fed for 6 weeks either a chow diet (Ctrl), or a chow diet supplemented with 1.5% or 15% (SA1.5% and SA15% resp.) energy from SA. Fasting glycemia was measured once a week and HbA1c before and after supplementation. An oral glucose tolerance test (OGTT) was performed at the end of the supplementation. Gene expression was determined by transcriptomic analysis on the liver of the Ctrl and SA15% groups. Results-After 42 days of supplementation, fasting glycemia and HbA1c were ~70% and ~25% lower in the SA15% group compared to other groups showing a beneficial effect of SA on hyperglycemia. During OGTT, blood glucose area under the curve (AUC) was reduced after SA15% compared to other groups. This effect was associated with a tendency for an improved insulin response. In the liver, Pck1 and FBP mRNA were statistically decreased in the SA15% compared to Ctrl suggesting a reduced hepatic glucose output induced by SA. Conclusions-Dietary supplementation of SA largely improves glycemic control in a mouse model of type 2 diabetes. This beneficial effect may be due (1) to a reduced hepatic glucose output resulting from transcriptional down regulation of key gluconeogenesis genes and (2) to an improved glucose induced-insulin secretion.

Description
The identification and characterization of subpopulations of cancer stem cells (CSCs) provide new understandings and possible therapeutic implications in cancer biology. We found the ovarian cancer sphere cells possessed CSCs properties maintained self renewal, drug resistance, and tumorigenesis. Using high-throughput microarray system, we identified common GO terms and pathway signatures significantly enriched in ovarian and breast cancer stem cells.

Description
Mocetinostat (MGCD) which is a kind of histone deacetylase inhibitors (HDACi) promotes human embryonic stem cells (hESCs) differentiation towards neural progenitor cells (NPCs). Application of HDAC inhibitors (HDACi) increased the expression of neuroectodermal markers once neural differentiation was initiated, thereby leading to more NPC generation.

Description
The skeleton is the most common metastasis site of breast cancer cells and the molecular underpinning of this process is incompletely understood. The tumor suppressor gene deleted in liver cancer-1 (DLC1) encodes a multi-domain protein including a RhoGTPase activating protein (RhoGAP) domain and has been reported to suppress the lung colonization of breast cancer cells. However, the role of DLC1 in breast cancer bone metastasis and the importance of RhoGAP-dependent and -independent pathways in this process remain unclear. Here, we showed that DLC1 silencing is linked to enhanced bone-tropism of breast cancer cell lines and poor prognosis of clinical samples.
