Article Abstract
High-throughput sequencing SELEX (HT-SELEX) is a powerful technique for unbiased determination of preferred target motifs of DNA-binding proteins in vitro. The procedure depends upon selection of DNA binding sites from a random library of oligonucleotides by purifying protein-DNA complexes and amplifying bound DNA using the polymerase chain reaction. Here, we describe an optimized step-by-step protocol for HT-SELEX compatible with Illumina sequencing. We also introduce a bioinformatic pipeline (eme_selex) facilitating the detection of promiscuous DNA binding by analyzing the enrichment of all possible k-mers. For complete details on the use and execution of this protocol, please refer to Pantier et al. (2021).

Identification of Targetable Mutations in Ovarian Cancer.
JCO Precis Oncol
September 2025
Division of Hematology and Oncology, University of California Los Angeles, Los Angeles, CA.
Purpose: mutations are classically seen in non-small cell lung cancers (NSCLCs), and EGFR-directed inhibitors have changed the therapeutic landscape in patients with -mutated NSCLC. The real-world prevalence of -mutated ovarian cancers has not been previously described. We aim to determine the prevalence of pathogenic or likely pathogenic mutations in ovarian cancer and describe a case of -mutated metastatic ovarian cancer with a durable response to osimertinib, an EGFR-directed targeted therapy.

JCO Precis Oncol
September 2025
Cell Biology and Biotherapy Unit, Istituto Nazionale Tumori IRCCS Fondazione G. Pascale, Napoli, Italy.
Purpose: Tumor comprehensive genomic profiling (CGP) may detect potential germline pathogenic/likely pathogenic (P/LP) alterations as secondary findings. We analyzed the frequency of potentially germline variants and large rearrangements (LRs) in the RATIONAL study, an Italian multicenter, observational clinical trial that collects next-generation sequencing-based tumor profiling data, and evaluated how these findings were managed by the enrolling centers.
Patients And Methods: Patients prospectively enrolled in the pathway-B of the RATIONAL study and undergoing CGP with the FoundationOne CDx assays were included in the analysis.
Nitrogen removal efficiency and pathways of the simultaneous nitrification and denitrification process under ultra-low oxygen conditions.

School of Environmental Science and Engineering, Southwest Jiaotong University, Chengdu, People's Republic of China.
To explore strategies for further reducing aeration energy consumption in the simultaneous nitrification and denitrification (SND) process, an SND reactor was constructed to treat low carbon-to-nitrogen (C/N) ratio domestic wastewater under ultra-low dissolved oxygen (DO) conditions (DO < 0.05 mg·L⁻). The effects of hydraulic retention time (HRT) and C/N ratio on nitrogen removal performance were systematically evaluated, and batch experiments were conducted to determine nitrification and denitrification rates.

DNA with high storage density can serve as an alternative storage medium to respond to the global explosion of data growth and become a powerful personal storage memory if an integrated compact device can store and handle large-scale data. Here, we incorporate a DNA cassette tape with 5.5 × 10 addressable data partitions (addressing rate up to 1570 partitions per second), a DNA loading capacity of 28.

Kobuviruses (family Picornaviridae, genus Kobuvirus) are enteric viruses that infect a wide range of both human and animal hosts. Much of the evolutionary history of kobuviruses remains elusive, largely due to limited screening in wildlife. Bats have been implicated as major sources of virulent zoonoses, including coronaviruses, henipaviruses, lyssaviruses, and filoviruses, though much of the bat virome still remains uncharacterized.
