Characterization of proteome-size scaling by integrative omics reveals mechanisms of proliferation control in cancer.

Almost all living cells maintain size uniformity through successive divisions. Proteins that over and underscale with size can act as rheostats, which regulate cell cycle progression. Using a multiomic strategy, we leveraged the heterogeneity of melanoma cell lines to identify peptides, transcripts, and phosphorylation events that differentially scale with cell size.

Signaling networks converge on TORC1-SREBP activity to promote endoplasmic reticulum homeostasis.

The function and capacity of the endoplasmic reticulum (ER) is determined by multiple processes ranging from the local regulation of peptide translation, translocation, and folding, to global changes in lipid composition. ER homeostasis thus requires complex interactions amongst numerous cellular components. However, describing the networks that maintain ER function during changes in cell behavior and environmental fluctuations has, to date, proven difficult.

Use of anthropometric measures to predict insulin resistance.

Objective: Obesity is closely related to insulin-resistance (IR) but it is evaluated differently in the diverse definitions of the metabolic syndrome. The objective of this study was to verify the utility of different anthropometric measures to predict IR and to evaluate the best cut-off points.

Subjects And Method: We performed a cross-sectional study of the general population aged 40 to 70 years old (n=2,143); a simple random sample of 305 non-diabetic persons was obtained.

The concentrations of soluble vascular cell adhesion molecule-1 and lipids are independently associated with venous thromboembolism.

Background And Objectives: Venous thromboembolism (VTE) involves inflammation and a relation with dyslipidemia which remains controversial. The vascular cell adhesion molecule-1 (VCAM-1) is a ligand expressed by activated endothelium (and recruits leukocytes) whose soluble form (sVCAM-1) increases in atherosclerosis, severe hypertriglyceridemia or deep vein thrombosis (DVT) in acute phase. We analyzed the association between VTE (> 6 months after), sVCAM-1 and lipid concentrations.
