Choline deprivation is a recognized experimental approach to non-alcoholic steatohepatitis, while thioacetamide- (TAA) induced liver fibrosis resembles alcoholic liver fibrogenesis. In order to elucidate the effect of TAA on liver extracellular matrix composition under choline deprivation due to choline-deficient diet (CDD) administration, we evaluated the transcriptional and immunohistochemical (IHC) pattern of major hepatic matrix metalloproteinases (namely, MMP-2, -9) and their tissue inhibitors (TIMP-1, -2) in adult male albino Wistar rats at 30, 60 and 90 days...

BACKGROUND/AIMS: Hepatocellular carcinoma (HCC) is a major threat to human health. The condition carries a high risk of death; 45% of new cases occur in China. Surgical resection is the first choice for treatment of HCC, but 30.9% of patients experience recurrence within 6 months after the operation. To improve patient survival, we must determine how to reduce the probability of recurrence and metastasis and elucidate the underlying mechanism of disease. We therefore studied the effect of somatostatin octapeptide (octreotide) on the invasion and metastasis of HCC...

Selective estrogen receptor modulators (SERMs) have been developed to achieve beneficial effects of estrogens while minimizing their side effects. In this context, we decided to evaluate the protective effect of genistein, a natural SERM, on skin flap viability in rats and in a series of in vitro experiments on endothelial cells (migration, proliferation, antioxidant properties, and gene expression profiling following genistein treatment). Our results showed that administration of genistein increased skin flap viability, but importantly, the difference is only significant when treatment is started 3 days prior the flap surgery...

BACKGROUND: Basic science data suggest that acute kidney injury (AKI) induced by ischemia-reperfusion injury (IRI) is an inflammatory process involving the adaptive immune response. Little is known about the T-cell contribution in the very early phase, so we investigated if tubular cellular stress expressed by elevated cell cycle biomarkers is associated with early changes in circulating T-cell subsets, applying a bedside-to-bench approach. METHODS: Our observational pilot study included 20 consecutive patients undergoing endovascular aortic repair for aortic aneurysms affecting the renal arteries, thereby requiring brief kidney hypoperfusion and reperfusion...

Glioma is one of the most devastating and refractory cancers. The main factors underlying therapeutic failure include extremely invasive characteristics and lack of effective methods for drug delivery. Attenuated Salmonella strains presented a high concentration of tumor targets in various types of cancer models, suggesting a role as potential vectors for drug delivery. In this study, we genetically engineered an attenuated strain of Salmonella as an anti-invasive vector for the targeted delivery and expression of tissue inhibitor of metalloproteinases 2 (TIMP-2) in an orthotopic nude mouse model of glioma...

Most patients with chronic kidney disease (CKD) present with proteinuria and extracellular matrix (ECM) deposition in the interstitium. Matrix metalloproteinase-2 (MMP-2) is important for maintaining ECM metabolism and it affects the formation and development of CKD. Autophagy has been reported to be protective against renal tubular injury, but the role of autophagy related to ECM metabolism is unclear. Rab7 is a shared molecule of endocytosis and autophagy. The aim of this study is to explore the role of autophagy in regulating MMP-2 activity and to determine whether Rab7 functions in regulating MMP-2 activity and injury in albumin-overloaded TECs...

Over the last decade, the discovery of novel renal biomarkers and research on their use to improve medication effectiveness and safety has expanded considerably. Pharmacists are uniquely positioned to leverage this new technology for renal assessment to improve medication dosing and monitoring. Serum cystatin C is a relatively new, inexpensive, functional renal biomarker that responds more quickly to changing renal function than creatinine and is not meaningfully affected by age, sex, skeletal muscle mass, dietary intake, or deconditioning...
