Haprolid Inhibits Tumor Growth of Hepatocellular Carcinoma through Rb/E2F and Akt/mTOR Inhibition.

Background: Hepatocellular carcinoma (HCC) represents a major health burden with limited curative treatment options. There is a substantial unmet need to develop innovative approaches to impact the progression of advanced HCC. Haprolid is a novel natural component isolated from myxobacteria.

Two patients with intestinal failure requiring home parenteral nutrition, a NOD2 mutation and tuberculous lymphadenitis.

Background: Mutations in the NOD2 gene are a significant risk factor to acquire intestinal failure requiring home parenteral nutrition. Tuberculous lymphadenitis is the main manifestation of extrapulmonary tuberculosis. Defects in the innate immunity, including NOD2 mutations, may increase the risk for acquiring infections caused by M.

NOD2 mutations are associated with the development of intestinal failure in the absence of Crohn's disease.

Background & Aims: Short bowel syndrome (SBS) and intestinal failure (IF) are multi-factorial conditions which in adults result from extensive intestinal resection. NOD2 is an intracellular pattern recognition receptor associated with CD. An unexpected high frequency of NOD2 mutations has been found in patients undergoing intestinal transplantation (35%).

Quorum sensing in the probiotic bacterium Escherichia coli Nissle 1917 (Mutaflor) - evidence that furanosyl borate diester (AI-2) is influencing the cytokine expression in the DSS colitis mouse model.

Background: "Quorum sensing" (QS) is the phenomenon which allows single bacterial cells to measure the concentration of bacterial signal molecules. Two principle different QS systems are known, the Autoinducer 1 system (AI-1) for the intraspecies communication using different Acyl-homoserine lactones (AHL) and AI-2 for the interspecies communication. Aim of this study was to investigate QS of Escherichia coli Nissle 1917 (Mutaflor).

Intestinal anion exchanger down-regulated in adenoma (DRA) is inhibited by intracellular calcium.

The Na/H exchanger 3 (NHE3) and the Cl/HCO(3) exchanger down-regulated in adenoma (DRA) together facilitate intestinal electroneutral NaCl absorption. Elevated Ca(2+)(i) inhibits NHE3 through mechanisms involving the PDZ domain proteins NHE3 kinase A regulatory protein (E3KARP) or PDZ kidney 1 (PDZK1). DRA also possesses a PDZ-binding motif, but the roles of interactions with E3KARP or PDZK1 and Ca(2+)(i) in DRA regulation are unknown.

Prognostic implications of BAX protein expression and microsatellite instability in all non-metastatic stages of primary colon cancer treated by surgery alone.

Purpose: This study examined whether the apoptosis-related protein, BAX, or the microsatellite-instability phenotype provide prognostic information in patients with resected colon cancer.

Methods: A total of 371 stage I-III patients that previously underwent radical surgery were included (mean follow-up 51.8 months).

Epigenetic combination therapy as a tumor-selective treatment approach for hepatocellular carcinoma.

Background: Innovative epigenetic therapeutics comprise histone deacetylase inhibitors (HDAC-I) and demethylating agents (DA). It was recently found that HDAC-I compounds exhibit profound therapeutic activities against hepatocellular carcinoma (HCC). A comprehensive preclinical investigation was performed on the potential of a combined HDAC-I/DA epigenetic regimen for the highly chemotherapy-resistant HCC entity.

Low BAX protein expression correlates with disease recurrence in preoperatively irradiated rectal carcinoma.

Purpose: To determine the prognostic impact of BAX in correlation to its upstream effector p53 as well as clinicopathologic variables and patient outcome in preoperatively irradiated rectal carcinoma.

Methods And Materials: We investigated 92 rectal carcinoma patients treated by preoperative radiotherapy to a total dose of 30 Gy followed by surgery. Median follow-up was 71 months.

Promoter methylation of INK4a/ARF as detected in bile-significance for the differential diagnosis in biliary disease.

Purpose: There is a need to enhance endobiliary cytotechniques by molecular marker lesions. This is of special significance for patients with primary sclerosing cholangitis, a disease predisposing for the development of cholangiocarcinoma. The INK4a/ADP ribosylation factor (ARF) locus encodes two tumor suppressor genes: p16INK4a and p14ARF.
