Unlabelled: Half of patients with KRAS wild-type colorectal cancer do not benefit from adding anti-epithelial growth factor receptor (EGFR) to standard chemotherapy regimens. This retrospective study was performed in 94 patients with metastatic colorectal cancer (mCRC) treated in the second line with cetuximab and chemotherapy. Signal transducer and activator of transcription 3 (STAT3) phosphorylation in tumor cells was correlated with decreased median progression-free survival and overall survival (OS).

Introduction: Endothelial dysfunction (ED) participates to atherogenesis associated to rheumatoid arthritis. We recently reported increased arginase activity/expression in vessels from adjuvant-induced arthritis (AIA) rats. In the present study, we investigated the effects of a curative treatment with the arginase inhibitor Nw-hydroxy-nor-L-arginine (nor-NOHA) on vascular dysfunction in AIA rats.

Background: Hepatocellular carcinoma (HCC) is the most common primary liver cancer, usually arising after years of chronic liver inflammation that could result from viral infections such as hepatitis B virus (HBV) and hepatitic C virus (HCV) infections. Human cytomegalovirus (HCMV) infects primary human hepatocytes and remains an important cause of morbidity in immunocompromised persons where it may manifest as symptomatic end-organ disease including hepatitis. The goal of the present study was to determine a potential correlation between HCMV infection and the appearance of HCC.

The analysis of KRAS mutations has become a prerequisite for anti-epidermal growth factor receptor therapy in patients with metastatic colorectal cancers. KRAS mutations are associated with resistance to treatment by monoclonal antibodies such as cetuximab and panitumumab and thus are correlated with a shorter progression-free survival. BRAF mutations also may play a role in treatment decisions.

Purpose: Investigate the genotype-phenotype correlations for five TGFBI (transforming growth factor, beta-induced) mutations including one novel pathogenic variant and one complex allele affecting the fourth FAS1 domain of keratoepithelin, and their potential effects on the protein's structure.

Methods: Three unrelated families were clinically diagnosed with lattice corneal dystrophy (CD) and one with an unclassified CD of Bowman's layer. Mutations in the TGFBI gene were detected by direct sequencing, and the functional impact of each variant was predicted using in silico algorithms.

The role of natural killer group 2, member D receptor (NKG2D)-expressing natural killer (NK) cells in tumor immunosurveillance is now well established. Nevertheless, tumor progression occurs despite tumor immunosurveillance, leading to cancer persistence in immunocompetent hosts. STAT3 plays a pivotal role both in oncogenic functions and in immunosuppression.

Background: Liquid-based cytology (LBC) for cervical cancer screening presents the advantage that cytological and virological investigations can be undertaken from the same specimen. Nevertheless, the fixative may alter DNA integrity and the sample may be inadequate for HPV DNA detection. The Novaprep(®) Vial Test (NVT) (Novacyt, Vélizy-Villacoublay, France) is a new device dedicated to LBC which permits an automated cell spreading over slides and an automated cell sampling for molecular analyses.

Integration of human papillomavirus (HPV) DNA into the host cell genome is a frequent event in cervical carcinogenesis, even though this phenomenon does not seem to be mandatory for cervical cancer development. Our objective was to describe the load and physical state of HPV type 16 (HPV16) DNA in a series of cervical samples representative of the natural history of cervical cancer. We used a combination of three real-time PCR assays targeting E6, E2, and albumin genes to calculate HPV16 load (E6 and albumin) and the E2/E6 ratio as a surrogate of integration.

Anti-TNF-alpha agents have been tried in cases of refractory sarcoidosis, giving favourable results. Thus, the occurrence of a granulomatous disease in a patient receiving such drug seems paradoxical. We describe 2 patients with inflammatory rheumatic disease, the first with ankylosing spondylitis, the second with rheumatoid arthritis, under anti-TNF-alpha treatment (infliximab and etanercept respectively) who developed non-caseating granulomas of the lungs and lymph nodes consistent with the diagnosis of sarcoidosis.

Introduction: Cervical intraepithelial neoplasia (CIN) 2 and CIN3 lesions clearly represent precancerous states even if some of them would heal spontaneously. Management is based on surgical excision of part of the uterine cervix because such lesions can potentially progress into carcinomas. In most cases, this treatment leads to the cure of intraepithelial lesions.

Background: Echinococcus multilocularis growth and persistent granuloma, which lead to the development of the severe parasitic disease alveolar echinococcosis (AE), might be caused by abnormal expression of stress-induced proteins, with subsequent abnormalities in T cell activation. Similar to its involvement in tumors, the NKG2D-major histocompatability complex class I chain-related molecules A and B (MICA/B) signaling system could be involved in host-parasite interactions; however, its involvement in helminthic diseases has never been studied.

Methods: We studied MICA/B, NKG2D, and transforming growth factor-beta (TGF-beta) expression on liver sections and measured levels of soluble MICA in serum samples obtained from patients with progressive AE.
