Transcription factor (TF) gene knockout or knockdown experiments provide comprehensive downstream effects on gene regulation. However, distinguishing primary direct effects from secondary effects remains challenging. To assess the direct effect of TF binding events, we present a protocol for establishing a doxycycline (Dox)-inducible CRISPRd system in human pluripotent stem cells (hPSCs). We describe the steps for establishing CRISPRd host hPSCs, designing and preparing single-guide RNA (sgRNA) expression lentivirus vectors, generating CRISPRd hPSCs transduced with sgRNAs, and analyzing CRISPRd TF-block effects by chromatin immunoprecipitation (ChIP)-qPCR. For complete details on the use and execution of this protocol, please refer to Matsui et al..

The neural tube, the embryonic precursor to the vertebrate central nervous system, comprises distinct progenitor and neuronal domains, each with specific proliferation programs. In this study, we identified TMEM196, a novel transmembrane protein that plays a crucial role in regulating cell proliferation in the floor plate in chick embryos. TMEM196 is expressed in the floor plate, and its overexpression leads to reduced cell proliferation without affecting the pattern formation of the neural tube.

Introduction: To evaluate the effectiveness of noninvasive positive pressure ventilation (NPPV) versus standard therapy in severe asthma exacerbations through meta-analysis.

Methods: Nine randomized controlled trials (344 patients) were analyzed from inception to August 2024. Primary outcomes included respiratory rate, forced expiratory volume in first second (FEV1), and oxygen saturation (SpO2).

Background: Pharmacy-to-dose (PTD) services describe an established practice where providers consult pharmacists for various medication dosing. In 2019, several institutions approved a daptomycin protocol, which allowed pharmacists to select doses based on provider-selected indications, renal function, and body mass index (BMI).

Objective: This study aims to determine the utility of a daptomycin PTD consult service.

Background: Despite extensive analysis, the dynamic changes in prostate epithelial cell states during tissue homeostasis as well as tumor initiation and progression have been poorly characterized. However, recent advances in single-cell RNA-sequencing (scRNA-seq) technology have greatly facilitated studies of cell states and plasticity in tissue maintenance and cancer, including in the prostate.

Methods: We have performed meta-analyses of new and previously published scRNA-seq datasets for mouse and human prostate tissues to identify and compare cell populations across datasets in a uniform manner.

Background And Aims: Oncogenic KRAS mutations are present in approximately 90% of pancreatic ductal adenocarcinoma (PDAC). However, Kras mutation alone is insufficient to transform precancerous cells into metastatic PDAC. This study investigates how KRAS-mutated epithelial cells acquire the capacity to escape senescence or even immune clearance, thereby progressing to advanced PDAC.
