Competition between a transmembrane helix on Scap and a membrane cholesterol regulates Scap–Insig interaction and SREBP activation

Proceedings of the National Academy of Sciences
Cholesterol homeostasis in mammalian cells relies on the interaction between two endoplasmic reticulum (ER) sterol-sensing membrane proteins, Scap and Insig. Their interaction regulates activation of transcription factors called sterol regulatory element–binding proteins (SREBPs) that control genes for cholesterol biosynthesis and uptake.

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

Journal of Polymer Science, Volume 64, Issue 16, Page 3364-3381, 15 August 2026.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...

Design and Optimization of High‐Efficiency Se1‐xTex Thin‐Film Solar Cells via Interface and Back‐Contact Engineering

Advanced Theory and Simulations, Volume 9, Issue 8, August 2026.
SCAPS‐1D modeling shows that bandgap‐engineered Se0.75Te0.25 (Eg ≈ 1.35 eV) can support high‐efficiency thin‐film photovoltaics through absorber, interface, and rear‐contact optimization. A MoOx‐based device reaches 21.94% PCE, while an HTL‐free configuration with a 5.5 eV rear‐contact work function achieves 21.59%.

Simvastatin Induces Apoptosis but Attenuates Migration in SCAPs

International Dental Journal
Simvastatin has emerged as having a promising role in controlling stem cell behaviours. This study aimed to evaluate the effects of simvastatin on the viability, growth, and migration of stem cells isolated from apical papillae (SCAPs) in vitro. SCAPs were isolated and characterised.

Effects of Stromal Cell‐Derived Factor 1 on Osteoblast Activity During Orthodontic Tooth Movement

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Objective This study aimed to clarify the relationship between stromal cell‑derived factor 1 (SDF‑1) and osteoblast‐related responses in periodontal ligament (PDL) during orthodontic tooth movement (OTM) after tooth extraction, based on the hypothesis that local inhibition of SDF‑1/C‑X‑C chemokine receptor type 4 (CXCR4) signaling with the ...

Selected monosaccharides in cancer: Metabolic routing, post‐translational modification, immunity and therapeutic potential

Clinical and Translational Discovery, Volume 6, Issue 4, August 2026.
Glucose, galactose, mannose and fructose can either fuel or fight tumours by rewiring metabolism and immunity. Their context‐dependent double‐edged nature suggests that precisely targeted monosaccharide interventions could become a new pillar of precision oncology.

The evolving landscape of the Warburg effect in gastric cancer: From molecular mechanisms to targeted therapy

Clinical and Translational Medicine, Volume 16, Issue 8, August 2026.
Hypoxia, oncogenic signaling, transcriptional and epigenetic remodeling, and H. pylori–microbiota interactions drive the Warburg effect in gastric cancer. Enhanced glycolysis and lactate export support biosynthesis, remodel the tumor microenvironment, promote stromal activation and immune suppression, and reveal actionable biomarkers and therapeutic ...

Immunometabolic Dysregulation in Obesity: Integrating Macrophage Polarization, Metabolic Reprogramming, and Gut Microbiota Crosstalk

Immunity, Inflammation and Disease, Volume 14, Issue 8, August 2026.
ABSTRACT Background Obesity is characterized by chronic low‐grade systemic inflammation, in which adipose tissue macrophages (ATMs) play a pivotal role in driving immune and metabolic dysfunction. Objective This review summarizes current evidence on the roles of ATMs in obese adipose tissue and examines how macrophage polarization and metabolic ...
