Article Abstract
Purpose Of Review: Next-generation sequencing is becoming more accessible. This review focuses on the clinical application of somatic and germline sequencing to genitourinary oncology.
Recent Findings: Germline variants have been increasingly recognized as contributing to the development of genitourinary malignancies, particularly in patients with advanced disease. A variety of commercial and institutional technologies are in use to detect variants, with newer tools focused on integrating these results into the clinical workflow.
Summary: DNA sequencing is becoming a valuable tool in caring for patients with genitourinary malignancies. Performing both somatic and germline sequencing will likely become standard practice. Interpretation and clinical application of these results can be challenging and often requires multidisciplinary expertise.
PIWI-interacting RNAs (piRNAs) are small non-coding RNAs that bind to the PIWI subclass of the Argonaute protein family and are essential for maintaining germline integrity. Initially discovered in , PIWI proteins safeguard piRNAs, forming ribonucleoprotein (RNP) complexes, crucial for regulating gene expression and genome stability, by suppressing transposable elements (TEs). Recent insights revealed that piRNAs and PIWI proteins, known for their roles in germline maintenance, significantly influence mRNA stability, translation and retrotransposon silencing in both stem cells and bodily tissues.
Immunoglobulins are important components of humoral immunity and play a crucial role in protecting the body from external antigens. The Arctic fox is an important member of furbearer farming, but due to the lack of research on the immune system of the Arctic fox, animal welfare regarding Arctic fox farming has still not received enough attention. In this study, we used the Arctic fox as a research subject, described the gene locus structure of the Arctic fox immunoglobulin germline by genome comparison, and analysed the mechanism of expression diversity of the antibody pool of the Arctic fox by rapid amplification of cDNA 5' ends and high-throughput sequencing.
Purpose: Although germline genetic testing (GT) is recommended for all patients with ovarian cancer (OC) and some patients with endometrial cancer (EC), uptake remains low with multiple barriers. Our center performs GT in parallel with somatic testing via a targeted sequencing assay (MSK-IMPACT) and initiates testing in oncology clinics (mainstreaming). We sought to optimize our GT processes for OC/EC.
Mitochondria, cellular powerhouses, harbor DNA (mtDNA) inherited from the mothers. MtDNA mutations can cause diseases, yet whether they increase with age in human germline cells-oocytes-remains understudied. Here, using highly accurate duplex sequencing of full-length mtDNA, we detected mutations in single oocytes, blood, and saliva in women between 20 and 42 years of age.
