The nuclear receptor subfamily 5, Group A, Member 1 (NR5A1) gene encodes steroidogenic factor 1 (SF1), which is necessary for development of steroid hormone-producing tissues including the gonad and adrenal gland. An induced pluripotent stem cell line (iPSC) LCHi002-B was generated from a participant with differences (disorders) of sex development (DSD) and multiple genetic variants including a large deletion in NR5A1, and three single nucleotide changes in DYNC2H1, PDE4D, and ZFPM2. The line presented typical morphology, expressed stem cell markers, differentiated into three germ layers, had normal karyotype, was mycoplasma-free, and carried mutations in NR5A1, DYNC2H1, PDE4D, and ZFPM2.

Background: Adolescents and young adults (AYA) with cystic fibrosis (CF) are at risk for deviating from their daily treatment regimen due to significant time burden, complicated daily therapies, and life stressors. Developing patient-centric, effective, engaging, and practical behavioral interventions is vital to help sustain therapeutically meaningful self-management.
Objective: This study aimed to devise and refine a patient-centered telecoaching intervention to foster self-management in AYA with CF using a combination of intervention development approaches, including an evidence- and theory-based approach (ie, applying existing theories and research evidence for behavior change) and a target population-centered approach (ie, intervention refinement based on the perspectives and actions of those individuals who will use it).

MTHFD2 is highly overexpressed in breast cancer tissues, indicating that it might be used as a target in breast cancer treatment. This study aims to determine the role of MTHFD2 in breast cancer cell proliferation and the molecular pathways involved. In order to investigate MTHFD2 gene expression and its downstream pathways in breast cancer, we started our inquiry with a bioinformatics analysis.

Reproducing intestinal cells in vitro is important in pharmaceutical research and drug development. Caco-2 cells and human iPS cell-derived intestinal epithelial cells are widely used, but few evaluation systems can mimic the complex crypt-villus-like structure. We attempted to generate intestinal cells mimicking the three-dimensional structure from human iPS cells.

Introduction: Patients with bipolar disorder (BD) demonstrate episodic memory deficits, which may be hippocampal-dependent and may be attenuated in lithium responders. Induced pluripotent stem cell-derived CA3 pyramidal cell-like neurons show significant hyperexcitability in lithium-responsive BD patients, while lithium nonresponders show marked variance in hyperexcitability. We hypothesize that this variable excitability will impair episodic memory recall, as assessed by cued retrieval (pattern completion) within a computational model of the hippocampal CA3.

Calreticulin (CALR) mutations are detected in around 20% of patients with primary and post-essential thrombocythemia myelofibrosis (MF). Regardless of driver mutations, patients with splenomegaly and symptoms are generally treated with JAK2-inhibitors, most commonly ruxolitinib. Recently, new therapies specifically targeting the CALR mutant clone have entered clinical investigation.
