AI Article Synopsis

  • The organization of the genome within the cell nucleus is crucial for various cellular functions like gene expression and DNA repair.
  • A new method has been developed to measure the pairing of DNA locations during homologous recombination at double-strand breaks in yeast cells.
  • This technique uses a tagging system to visualize DNA interactions and confirms the repair products, revealing the timing and physical contact between homologous DNA during the repair process.

Article Abstract

The precise organization of the genome inside the cell nucleus is vital to many cell functions including gene expression, cell division, and DNA repair. Here we describe a method to measure pairing of DNA loci during homologous recombination (HR) at a site-specific double-strand break (DSB) in Saccharomyces cerevisiae. This method utilizes a chromosome tagging system in diploid yeast cells to visualize both the DNA at the break site and the homologous DNA that serves as a repair template. DNA repair products are confirmed in parallel by genomic blot. This visualization method provides insight into the physical contact that occurs between homologous loci during HR and correlates physical interaction with the timing of DNA repair.

Chemotherapy resistance has long stood in the way of therapeutic advancement for lung cancer patients, the malignant tumor with the highest incidence and fatality rate in the world. Patients with lung adenocarcinoma (LUAD) now have a dismal prognosis due to the development of cisplatin (DDP) resistance, forcing them to use more costly second-line therapies. Therefore, overcoming resistance and enhancing patient outcomes can be achieved by comprehending the regulatory mechanisms of DDP resistance in LUAD.

Cancer, a complicated disease characterized by aberrant cellular metabolism, has emerged as a formidable global health challenge. Since the discovery of abnormal aldolase A (ALDOA) expression in liver cancer for the first time, its overexpression has been identified in numerous cancers, including colorectal cancer (CRC), breast cancer (BC), cervical adenocarcinoma (CAC), non-small cell lung cancer (NSCLC), gastric cancer (GC), hepatocellular carcinoma (HCC), pancreatic cancer adenocarcinoma (PDAC), and clear cell renal cell carcinoma (ccRCC). Moreover, ALDOA overexpression promotes cancer cell proliferation, invasion, migration, and drug resistance, and is closely related to poor prognosis of patients with cancer.

Chemotherapy remains the cornerstone of cancer treatment; however, its efficacy is frequently compromised by the development of chemoresistance. Multidrug resistance (MDR), characterized by the refractoriness of cancer cells to a wide array of chemotherapeutic agents, presents a significant barrier to achieving successful and sustained cancer remission. One critical factor contributing to this chemoresistance is the overexpression of ATP-binding cassette (ABC) transporters.

Background: Bronchopulmonary dysplasia (BPD) is a chronic lung disease in premature infants caused by an imbalance between lung injury and lung repair in the developing immature lungs of the newborn. Pulmonary inflammation is an important feature in the pathogenesis of BPD. The aim of this study was to evaluate the relationship between the inflammatory microenvironment and the levels of visfatin and nesfatin-1, which are among the new adipocytokines, in BPD patients.
