Siberian permafrost is a unique environment inhabited with diverse groups of microorganisms. Among them, there are numerous producers of biotechnologically relevant enzymes including lipases and esterases. Recently, we have constructed a metagenomic library from a permafrost sample and identified in it several genes coding for potential lipolytic enzymes. In the current work, properties of the recombinant esterases obtained from this library are compared with the previously characterized lipase from Psychrobacter cryohalolentis and other representatives of the hormone-sensitive lipase family...

Intestinal subepithelial myofibroblasts (SEMFs) exert a profibrotic role in Crohn's disease (CD). Tumor necrosis factor-like cytokine 1A (TL1A) and its receptors, death-domain receptor 3 (DR3) and decoy receptor 3 (DcR3), are mucosal factors with significant involvement in experimental inflammation and CD. We aimed to determine the regulation of expression of this system of proteins in SEMFs and intestinal epithelial cells. The relative amount of mRNA transcripts for TL1A, DR3, and DcR3 was measured by real-time reverse transcription polymerase chain reaction in cultured primary SEMFs, colonic myofibroblast cell line 18CO, and epithelial cell line HT29...

Osteopontin (OPN) is a multifunctional cytokine involved in carcinogenesis. Serum levels of OPN, vascular endothelial growth factor (VEGF), and matrix metalloproteinase-9 (MMP-9) were measured by ELISA in 90 lung cancer patients. OPN levels were elevated in patients compared to controls (p <.0001). Smokers, patients with worse performance status, and weight loss exhibited higher OPN levels (p =.0012,.00036, and.0003, respectively). Increased OPN levels were associated with worse survival (p =.0018). Finally, OPN levels were positively correlated with both VEGF (p =...

OBJECTIVES: Active smokers with non-small-cell lung cancer (NSCLC) have increased erlotinib metabolism versus non-smoking patients, which reduces exposure. Therefore, an increased erlotinib dose may be beneficial. The CurrentS study (NCT01183858) assessed efficacy and safety of 300mg erlotinib (E300) as second-line therapy in current smokers with locally advanced or metastatic NSCLC versus the standard 150mg dose (E150). MATERIALS AND METHODS: Patients with stage IIIB/IV NSCLC (current smokers who failed first-line platinum-based chemotherapy) were randomized to receive E150 or E300 until progression/death/unacceptable toxicity...

The clinical presentation of diabetes sometimes overlaps, contributing to ambiguity in the diagnosis. Thus, circulating pancreatic islet-enriched microRNAs (miRNAs) might be useful biomarkers of β-cell injury/dysfunction that would allow more accurate subtyping of diabetes. We measured plasma levels of selected miRNAs in subjects with prediabetes (n = 12), type 2 diabetes (T2D, n = 31), latent autoimmune diabetes of adults (LADA, n = 6) and type 1 diabetes (T1D, n = 16) and compared them to levels in healthy control subjects (n = 27)...
