Application of next generation sequencing (NGS) has shed light on the molecular heterogeneity of hematological malignancies. NGS panels targeting recurrent mutations have become common in many large centers and commercial laboratories. However, its impact in clinical practice is unclear. We sought to characterize the use of NGS at a tertiary care center in an observational study of 343 patients with suspected hematological malignancies. We found that NGS changed or refined the clinical and pathologic diagnosis in 9% of patients and affected management decisions in 65% (including clinical trial eligibility, targeted therapy selection, and consideration for stem cell transplantation). This study emphasizes early incorporation of NGS in clinical practice while also highlighting the present limitations. As our understanding of these disorders increases and more clinically relevant genetic targets emerge, it will be important to refine the molecular testing strategy to deliver personalized medicine given the high cost associated with this technology.

PHIStruct: Improving phage-host interaction prediction at low sequence similarity settings using structure-aware protein embeddings.
Bioinformatics
January 2025
Bioinformatics Lab, Advanced Research Institute for Informatics, Computing and Networking, De La Salle University, Manila, 1004, Philippines.
Motivation: Recent computational approaches for predicting phage-host interaction have explored the use of sequence-only protein language models to produce embeddings of phage proteins without manual feature engineering. However, these embeddings do not directly capture protein structure information and structure-informed signals related to host specificity.
Results: We present PHIStruct, a multilayer perceptron that takes in structure-aware embeddings of receptor-binding proteins, generated via the structure-aware protein language model SaProt, and then predicts the host from among the ESKAPEE genera.
An Efficient and Cost-Effective Novel Strategy for Identifying CRISPR-Cas-Mediated Mutants in Plant Offspring.
CRISPR J
January 2025
Plant Biotechnology Research Center, Fudan-SJTU-Nottingham Plant Biotechnology R&D Center, School of Agriculture and Biology, Shanghai Jiao Tong University, Minhang, Shanghai, China.
The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 system has revolutionized targeted mutagenesis, but screening for mutations in large sample pools can be time-consuming and costly. We present an efficient and cost-effective polymerase chain reaction (PCR)-based strategy for identifying edited mutants in the T generation. Unlike previous methods, our approach addresses the challenges of large progeny populations by using T generation sequencing results for genotype prediction.

Division of Animal Biotechnology, Faculty of Veterinary Sciences & Animal Husbandry, SKUAST-K, Srinagar, India.
Background: The identification of helminth parasites in Schizothorax spp. from Kashmir, including Schyzocotyle acheilognathi, Pomphorhynchus kashmirensis, and Adenoscolex oreini, is hindered by morphological limitations and high intraspecific variation. While previous studies have relied on morphological diagnosis, a comprehensive molecular characterization is lacking.

Division of Forensic Medicine and Toxicology, Department of Pathology, Faculty of Health Science, University of Cape Town, Cape Town, South Africa.
The ForenSeq™ DNA Signature Prep kit has not been thoroughly tested with crude buccal swab lysates in large-scale population studies using massively parallel sequencing (MPS). Commonly used lysis buffers for swabs intending to undergo direct polymerase chain reaction (PCR) are SwabSolution™ and STR GO! Lysis Buffers, and these have been successfully used to generate population data using capillary electrophoresis (CE) systems. In this study, we investigated the performance and optimisation of SwabSolution™ and STR GO! lysates with the ForenSeq™ DNA Signature Prep workflow and addressed the challenge of failed MPS profiles in initial trials.

Neurology
January 2025
Department of Neurology, Massachusetts General Hospital, Boston.
Background And Objectives: Rolandic epilepsy (RE), the most common childhood focal epilepsy syndrome, is characterized by a transient period of sleep-activated epileptiform activity in the centrotemporal regions and variable cognitive deficits. Sleep spindles are prominent thalamocortical brain oscillations during sleep that have been mechanistically linked to sleep-dependent memory consolidation in animal models and healthy controls. Sleep spindles are decreased in RE and related sleep-activated epileptic encephalopathies.
