Unveiling Microbiota Profiles in Saliva and Pancreatic Tissues of Patients with Pancreatic Cancer.

The pancreas, previously considered a sterile organ, has recently been shown to harbor its own microbiota that may influence tumor biology and patient outcomes. Despite increasing interest in the impact of the microbiome on cancer, the relationship between pancreatic tissue and oral microbiomes in pancreatic ductal adenocarcinoma (PDAC) remains limited. In this study, the oral and pancreas tissue microbiomes of patients with PDAC were compared to patients with other periampullary cancers (DC/AC) and a healthy control group using 16S rRNA gene sequence analysis.

Cryptosporidiosis as an opportunistic infection in colorectal cancer patients.

Cryptosporidium spp. is an opportunistic protozoan parasite that primarily affects immunocompromised individuals, including those with colorectal cancer (CRC). This study investigates the prevalence and clinical significance of Cryptosporidium spp.

Association of 3'UTR variations of EGFR and KRAS oncogenes with clinical parameters in lung cancer tumours.

Bacground Information: Lung cancer is one of the leading types of cancer deaths worldwide, with approximately 2 million people diagnosed with lung cancer each year. In this study, we aimed to determine the exonic and 3'UTR sequences of EGFR, PIK3CA and KRAS genes in 39 sporadic lung cancer tumors and to reveal the changes in the miRNA binding profile of tumors with somatic variation in the 3'UTR region and to examine the relationship of these changes with clinical parameters.

Results: A statistically significant correlation was found between the presence of miRNA that could not bind to the 3'UTR region due to variation in at least one of the EGFR or KRAS genes and the presence of metastasis in the tumor.

A novel gene variant in a Turkish family with juvenile-onset open-angle glaucoma.

Background: Juvenile-onset open-angle glaucoma (JOAG) is a rare form of primary open-angle glaucoma (POAG) with an early age of onset before 40 years. Latent transforming growth factor-beta binding protein 2 (LTBP-2) is an extracellular matrix protein with a multi-domain structure and homology to fibrillins. LTBP2 gene variants have been associated with JOAG in a small number of patients.

Variant Analysis of miRNA Regulatory Genes in 35 Sporadic Lung Carcinoma Tumors.

Unlabelled: Lung cancer is one of the cancer types with the highest mortality worldwide. The most frequently mutated genes known to be clinically important in lung cancers are EGFR, BRAF, and KRAS genes. Therefore, the therapeutic agents developed are directed against variants that cause over-activation of the EGFR-KRAS-BRAF-BRAF-MEK/ERK signalling pathway.
