Antibiotic resistance in Helicobacter pylori: A mutational analysis from a tertiary care hospital in Kashmir, India

Conclusions: Tetracycline and quinolones could be the antibiotics of choice in the eradication of H. pylori in this region, while recurrence of the infection with H. pylori could be expected among patients receiving either metronidazole or clarithromycin, for eradication therapy. DST should be done on a routine basis utilising both phenotypic and genotypic methods to prevent further emergence of resistance in this region.

In this study, we found that TLR1/TLR2 expression predicted favorable prognosis of lung cancer patients. In the related mice tumor model, TLR1/TLR2 activation by synthetic bacterial lipoprotein (BLP), a TLR1/2 agonist, greatly inhibited tumor growth and selectively decreased monocytic MDSCs (M-MDSCs). Furthermore, BLP treatment redirected M-MDSC differentiation towards M1 macrophage through JNK pathway, and thus blocked the suppressive activity of M-MDSCs in a TLR2-dependent manner. Therefore, our data demonstrated that TLR2 could be a promising biomarker and a potential immunotherapeutic target for lung cancer.

We have generated an induced pluripotent stem cell (iPSC) line, IGIBi001-A from an Indian sickle cell patient with a homozygous HBB gene mutation using Sendai virus reprogramming system. Characterization of IGIBi001-A showed that these iPSCs are transgene-free and expressed pluripotent stem cell markers. They had a...

Immunotherapies such as checkpoint inhibitors have proven efficacy in patients with high level of microsatellite instability and refractory to routine chemotherapy. Despite this, immunotherapy-based treatment is seriously limited by cancer immunogenicity which are evolved to evade immune surveillance in many circumstances. Efforts are made by resear...

Publication date: Available online 15 June 2019Source: Nano TodayAuthor(s): Weijing Yang, Zijian Zhou, Joseph Lau, Shuo Hu, Xiaoyuan ChenAbstractImmunotherapy (e.g., checkpoint blockade, adoptive T cell therapy, cancer vaccine) has emerged as one of the most important treatment modalities for cancer in the past two decades. While these approaches are promising, the response rates observed in clinical trials are less than 30% due to tumor heterogeneity and complexity of the tumor microenvironment. Smart nanosystems have the potential to address some of the limitations associated with immunotherapy. Herein, we review applica...

NiceAbstractOncoproteomics is the systematic study of cancer samples using omics technologies to detect changes implicated in tumorigenesis. Recent progress in oncoproteomics is already opening new avenues for the identification of novel biomarkers for early clinical stage cancer detection, targeted molecular therapies, disease monitoring, and drug development. Such information will lead to new understandings of cancer biology and impact dramatically on the future care of can...

Abstract Base excision DNA repair (BER) is a vitally important pathway that protects the cell genome from many kinds of DNA damage, including oxidation, deamination, and hydrolysis. It involves several tightly coordinated steps, starting from damaged base excision and followed by nicking one DNA strand, incorporating an undamaged nucleotide, and DNA ligation. Deficiencies in BER are often embryonic lethal or cause morbid diseases such as cancer, neurodegeneration, or severe immune pathologies. Starting from the early 1980s, when the first mammalian cell lines lacking BER were produced by spontaneous mutagenesis, s...

This study demonstrates that NSCLC cells resistant to gefitinib (GR cells) displayed a significantly higher microsomal prostaglandin E synthase-1 (mPGES-1) expression and activity than parental cells. Overexpression of mPGES-1/prostaglandin E-2 (PGE-2) signaling in GR cells was associated with acquisition of mesenchymal and stem-like cell properties, nuclear EGFR translocation and tolerance to cisplatin. mPGES-1 inhibition reduced mesenchymal and stem-like properties, and nuclear EGFR translocation in GR cells. Consistently, inhibition of mPGES-1 activity enhanced sensitivity to cisplatin and responsiveness to gefitinib in...

Conclusion: In Mongolia, the prevalence of H. pylori resistance is high requiring bismuth quadruple therapy or susceptibility-based therapy to obtain acceptable cure rates. Introduction As in most developing countries, the prevalence of Helicobacter pylori infection is high in Mongolia (Nyamdavaa, 2013) with reported prevalence ranging of 80% among adults (Matsuhisa et al., 2015; Khasag et al., 2018), 64% among adolescents, and 65 and 100% among pediatric patients with gastric comorbidity (Go, 2013). Gastric cancer is a common problem in Mongolia; an age-standardized rate of 33.1 per 100,000, which is the second hi...

Abstract Helicobacter pylori (Hp) is a major human pathogen causing chronic, progressive gastric mucosal damage and is linked to gastric atrophy and cancer. Hp-positive individuals constitute the major reservoir for transmission of infection. There is no ideal treatment for Hp. Hp infection is not cured by a single antibiotic, and sometimes, a combined treatment with three or more antibiotics is ineffective. Atrophic gastritis (AG) is a chronic disease whose main features are atrophy and/or intestinal metaplasia of the gastric glands, which arise from long-standing Hp infection. AG is reportedly linked to an incre...
