Long-term high fat diet aggravates the risk of lung fibrosis and lung cancer: transcriptomic analysis in the lung tissues of obese mice.

Background: Previous studies reported significant relationships between obesity and pulmonary dysfunction. Here, we investigated genetic alterations in the lung tissues of high fat diet (HFD) induced obese mouse through transcriptomic and molecular analyses.

Methods: Eight-week-old male C57BL/6J mice were fed either a normal chow diet (NCD) or HFD for 12 weeks.

Cost-Effective Laser Powder Bed Fusion of Ti-6Al-4V Grade 5: The Effect of Expanding Powder Size Distribution on Mechanical Performance.

This study aims to assess the feasibility of expanding the powder size distribution (PSD) of Ti-6Al-4V grade 5 powder for LPBF to achieve cost reduction. Parameter optimization to minimize the degradation of mechanical properties due to the expanded particle size distribution was conducted. Mechanical tests for specimens built using optimized parameters revealed minor reductions in strength: 3.

Uncovering potential causal genes for undiagnosed congenital anomalies using an in-house pipeline for trio-based whole-genome sequencing.

Background: Congenital anomalies (CAs) encompass a wide spectrum of structural and functional abnormalities during fetal development, commonly presenting at birth. Identifying the cause of CA is essential for accurate diagnosis and treatment. Using a target-gene approach, genetic variants could be found in certain CA patients.

hsa-mir-483-3p modulates delayed breast cancer recurrence.

Patients with estrogen receptor-positive breast cancer undergoing continuous adjuvant hormone therapy often experience delayed recurrence with tamoxifen use, potentially causing adverse effects. However, the lack of biomarkers hampers patient selection for extended endocrine therapy. This study aimed to elucidate the molecular mechanisms underlying delayed recurrence and identify biomarkers.

The microbial metabolite imidazole propionate dysregulates bone homeostasis by inhibiting AMP-activated protein kinase (AMPK) signaling.

Microbial metabolites provide numerous benefits to the human body but can also contribute to diseases such as obesity, diabetes, cancer, and bone disorders. However, the role of imidazole propionate (ImP), a histidine-derived metabolite produced by the intestinal microbiome, in bone metabolism and the development of osteoporosis is still poorly understood. In this study, we investigated the role of ImP and its underlying mechanisms in regulating bone homeostasis.
