Because GPS2 expression is down-regulated in some humans with obese and type 2 diabetes, the macrophage GPS-2/ABC-A1 pathway could be altered and contribute to atherogenesis.-Huang, Z., Liang, N., Damdimopoulos, A., Fan, R., Treuter, E. G protein pathway suppressor 2 (GPS2) links inflammation and cholesterol efflux by controlling lipopolysaccharide-induced ATP-binding cassette transporter A1 expression in macrophages.
In accordance with this role, we have shown that GPS2 presence in adipocytes modulates systemic metabolism by restricting the activation of insulin signaling during the fasted state, whereas in absence of GPS2, the adipose tissue is more efficient at lipid storage, and obesity becomes uncoupled from inflammation and insulin resistance.
By contrast, transplantation of GPS2-overexpressing bone marrow into two mouse models of obesity (ob/ob and diet-induced obesity) reduced inflammation and improved insulin sensitivity.

In disease-free survival, GPS 2 (P=0.019), with a tumor number ≥3 (P=0.004), and positive portal or venous invasion (P=0.034) were independent predictors of cancer recurrence in multivariate analysis.
Hypoalbuminemia (< or = 35 g/L) and GPS were predictive of toxicity; GPS 2 was predictive of increased grade 2/3 toxicity compared with patients with a GPS of 0 or 1 (P < .05).
Collectively, our data suggest that the GPS2-PPARα partnership in hepatocytes coordinates the progression of NAFLD in mice and in humans and thus might be of therapeutic interest.
Multivariate analysis demonstrated that GPS 2 (odds ratio [OR] 3.352; 95% confidence interval [CI] 1.049-10.71; p = 0.041) and preoperative ileus (OR 7.405; 95% CI 2.386-22.98; p = 0.001) were independent factors predictive of conversion from laparoscopic to open surgery.
Hepatocyte-specific Gps2 knockout in mice alleviates the development of diet-induced steatosis and fibrosis and causes activation of lipid catabolic genes.
Here we demonstrate that G protein pathway suppressor 2 (GPS2), a subunit of the nuclear receptor corepressor (NCOR) and histone deacetylase 3 (HDAC3) complex, has a central role in these alterations and accelerates the progression of NAFLD towards non-alcoholic steatohepatitis (NASH).

For the assessment of systemic inflammatory response using the GPS, patients were classified into three groups: Patients with normal serum albumin (<3.5 g/dl) and normal serum C-reactive protein (CRP) (≤1.0 mg/dl) were classified as GPS 0 (n=76), those with low serum albumin (<3.5 g/dl) or elevated serum CRP (>1.0 mg/dl) were classified as GPS 1 (n=58), and those with low serum albumin (<3.5 g/dl) and elevated serum CRP (>1.0 mg/dl) were classified as GPS 2 (n=10).
In overall survival, GPS 1 (P=0.042), GPS 2 (P<0.001) and positive portal or venous invasion (P<0.001) were independent predictors of poor patient outcome according to multivariate analysis.
Isolated reports of individual rearrangements of GPS2 in a prostate carcinoma cell line and in glioblastoma multiforme, each with different partner genes, recently emerged from high-throughput sequencing studies but have not been further evaluated for biological effect.
