Article Abstract

Despite significant therapeutic advances, metastatic CRPC (mCRPC) remains a lethal disease. Mutations in homologous recombination repair (HRR) genes are frequent in mCRPC, and tumors harboring these mutations are known to be sensitive to PARP inhibitors. The aim of this study was to verify the technical effectiveness of this panel in the analysis of mCRPC, the frequency and type of mutations in the / genes, as well as in the homologous recombination repair (HRR) genes. A total of 50 mCRPC cases were analyzed using a multi-gene next-generation sequencing panel evaluating a total of 1360 amplicons in 24 HRR genes. Of the 50 cases, 23 specimens (46.0%) had an mCRPC harboring a pathogenic variant or a variant of uncertain significance (VUS), whereas in 27 mCRPCs (54.0%), no mutations were detected (wild-type tumors). was the most commonly mutated gene (14.0% of samples), followed by (12.0%), and (6.0%). In conclusion, we have set up an NGS multi-gene panel that is capable of analyzing / and HRR alterations in mCRPC. Moreover, our clinical algorithm is currently being used in clinical practice for the management of patients with mCRPC.

The Discovery of RP-2119: A Potent, Selective, and Orally Bioavailable Polθ ATPase Inhibitor.

DNA polymerase theta (Polθ) plays a critical role in repairing DNA double-strand breaks through microhomology-mediated end joining (MMEJ) and has emerged as a key synthetic lethal drug target in cancers with homologous recombination (HR) deficiencies. Its inhibition has shown a strong potential to synergize with PARP inhibitors, particularly in tumors with deleterious or mutations. Here, we describe the discovery and preclinical development of RP-2119, a selective, potent, and bioavailable Polθ ATPase inhibitor.

Treatment of patients with platinum-resistant ovarian cancer is a major clinical challenge. We found that high expression of a meiotic protein, Synaptonemal Complex Protein 2 (SYCP2), is associated with platinum resistance and tyrosine kinase ABL1 inhibitor sensitivity in ovarian cancer. We demonstrate that tyrosine kinase ABL1 inhibitors inhibit cancer cell proliferation more efficiently in ovarian cancer cell lines with SYCP2 overexpression.

infections represent a significant public health concern. Despite their clinical relevance, the genetic determinants underlying bacterial fitness and virulence remain incompletely characterized. In this study, we systematically identified genes involved in host adaptation by generating a transposon mutant library and integrating a infection model with transposon sequencing (Tn-seq) technology.

Background: Sézary syndrome (SS) is an aggressive and leukemic variant of Cutaneous T-cell Lymphoma (CTCL) with an incidence of 1 case per million people per year. It is characterized by a complex and heterogeneous profile of genetic alteration ns that has so far precluded the development of a specific and definitive therapeutic intervention.

Methods: Deep-RNA-sequencing (RNA-seq) data were used to analyze the single nucleotide variants (SNVs) carried by 128 putative CTCL-driver genes, previously identified as mutated in genomic studies, in longitudinal SS samples collected from 17 patients subjected to extracorporeal photopheresis (ECP) with Interferon-α.

Meiotic crossovers promote correct chromosome segregation and the shuffling of genetic diversity. However, the measurement of crossovers remains challenging, impeding our ability to decipher the molecular mechanisms that are necessary for their formation and regulation. Here we demonstrate a novel repurposing of the single-nucleus Assay for Transposase Accessible Chromatin with sequencing (snATAC-seq) as a simple and high-throughput method to identify and characterize meiotic crossovers from haploid testis nuclei.
