Revealing the Genetic Diversity of Chinese Chlamydia trachomatis Strains Directly From Clinical Samples Through Selective Whole Genome Amplification.

Background: Chlamydia trachomatis is the causative agent of the most prevalent bacterial sexually transmitted infections globally. Whole genome sequencing is essential for molecular Chlamydia surveillance; however, its application is hampered by the pathogen's low abundance in clinical specimens and the expensive labor-intensive nature of existing enrichment methodologies for Chlamydia.

Methods: We developed a targeted whole genome amplification tool termed SWITCH by integrating phi29 DNA polymerase-mediated amplification with meticulously designed primer sets to enrich the C trachomatis genome, followed by whole genome sequencing.

A novel prognostic model predicts overall survival in patients with nasopharyngeal carcinoma based on clinical features and blood biomarkers.

This study aims to develop and validate a novel prognostic model to estimate overall survival (OS) in nasopharyngeal carcinoma (NPC) patients based on clinical features and blood biomarkers. We assessed the model's incremental value to the TNM staging system, clinical treatment, and Epstein-Barr virus (EBV) DNA copy number for individual OS estimation. We retrospectively analyzed 519 consecutive patients with NPC.

Upregulation of circ-0000745 in acute lymphoblastic leukemia enhanced cell proliferation by activating ERK pathway.

Acute lymphoblastic leukemia (ALL) is a common hematologic malignancy. Circular RNAs (circRNAs) have been reported as an important factor in regulating cellular process expressed in all hematopoietic compartment. But the molecular mechanism of circRNAs in ALL remain unclear.
