Article Abstract
BNIP3 is a BH3-only protein with both pro-apoptotic and pro-survival roles depending on the cellular context. It remains unclear how BNIP3 RNA level dictates cell fate decisions of cancer cells. Here, we undertook a quantitative analysis of BNIP3 expression and functions in single-cell datasets of various epithelial malignancies. Our results demonstrated that BNIP3 upregulation characterizes cancer cell subpopulations with increased fitness and proliferation. We further validated the upregulation of BNIP3 in liver cancer 3D organoid cultures compared with 2D culture. Taken together, the combination of perturbations using public single-cell datasets and experimental cancer modeling using organoids ushered in a new approach to address cancer heterogeneity.

Background: Platinum resistance poses a significant challenge in the treatment of osteosarcoma, leading to poor prognosis and limited therapeutic options. This study aims to develop a prognostic model by analyzing platinum-resistant genes (PRGs), focusing on their roles in lysosomal function and immune suppression.
Methods: We conducted a univariable Cox analysis to identify diagnostic-related genes (PRGs) from a training cohort of osteosarcoma patients.
Decoding the amniotic membrane transcriptome during equine ascending placentitis.

Despite its critical role in protecting the fetus, the amniotic membrane remains poorly understood in the context of disease response. The equine amniotic membrane is an important physical barrier to the amniotic compartment, and there is evidence that it may contribute to surfactant synthesis. Surfactants are essential for normal fetal lung development, and disruptions in its availability may be linked to future neonatal complications.

Background: Postnatal skeletal muscle development leads to increased muscle mass, strength, and mitochondrial function, but the role of mitochondrial remodeling during this period is unclear. This study investigates mitochondrial remodeling during postnatal muscle development and examines how constitutive autophagy deficiency impacts these processes.
Methods: We initially performed a broad RNA-Seq analysis using a publicly available GEO database of skeletal muscle from postnatal day 7 (P7) to postnatal day 112 (P112) to identify differentially expressed genes.

Objective Osteoporosis (OP) is a systemic skeletal disease that increases the risk of fractures by weaking bone. Hypoxia-inducible factor-1α (HIF-1α) plays a crucial role in osteogenesis and osteoblastic differentiation. The purpose of this study is to examine the underlying mechanism of HIF-1α overexpression and its impact on osteoblast development.

Background: Cardiac fibrosis plays a critical role in the progression of chronic cardiovascular conditions, with mitochondrial dysfunction acting as a central mechanism underlying pathological myocardial fibrosis. Increasing research shows that microRNAs may modulate the fibrotic process by regulating mitochondrial function via various pathways.
Aims: To examine the involvement of miR-17-5p in modulating mitochondrial autophagy and alleviating pathological cardiac fibrosis.
