Latent transforming growth factor-β-binding protein (LTBP)2 is a member of the fibrillin/LTBP superfamily of extracellular matrix proteins, and has been demonstrated to exhibit tumor-promoting and tumor-suppressive functions in different types of cancer. However, the function of LTBP2 in gastric cancer (GC) remains unknown. The aim of the present study was to investigate the expression and molecular function of LTBP2 in GC, and to evaluate its prognostic value for patients with GC. The results revealed that the expression of LTBP2 was upregulated in GC tissues and cell lines. Increased LTBP2 expression was associated with poor overall survival in patients with early-stage [tumor-node-metastasis (TNM) I/II] and late-stage (TNM III/IV) GC. Furthermore, silencing of LTBP2 effectively suppressed the proliferation, migration, invasion and epithelial-mesenchymal transition in GC cells. These results suggested that LTBP2 may be considered as a potential therapeutic target and a promising prognostic biomarker for human GC.

Primary open-angle glaucoma (POAG), known as a common ocular disease with genetic heterogeneity, is characterized by progressive optic disc atrophy and visual field defects. This study aimed to assess the contribution of previously reported POAG-associated genes and investigate potential functional variations and genotype-phenotype correlations in a Han Chinese population. DNA from 500 cases and 500 controls was pooled and sequenced using a customized panel of 398 candidate genes.

The zonular fibres are formed primarily of fibrillin-1, a large extracellular matrix (ECM) glycoprotein, and also contain other constituents such as LTBP-2, ADAMTSL6, MFAP-2 and EMILIN-1, amongst others. They are critical for sight, holding the crystalline lens in place and being necessary for accommodation. Zonulopathies refer to conditions in which there is a lack or disruption of zonular support to the lens and may clinically be manifested as ectopia lens (EL)-defined as subluxation of the lens outside of the pupillary plane or frank displacement (dislocation) into the vitreous or anterior segment.

Excessive deposition of fibrillar collagen in the interstitial extracellular matrix (ECM) of human lung tissue causes fibrosis, which can ultimately lead to organ failure. Despite our understanding of the molecular mechanisms underlying the disease, no cure for pulmonary fibrosis has yet been found. We screened a drug library and found that dextromethorphan (DXM), a cough expectorant, reduced the amount of excess fibrillar collagen deposited in the ECM in cultured primary human lung fibroblasts, a bleomycin mouse model, and a cultured human precision-cut lung slice model of lung fibrosis.

Article Synopsis
- * Researchers conducted various bioinformatics analyses to identify key genes related to AD and ferroptosis, ultimately spotlighting 51 significant genes, including CDK1 and LTBP2, and using machine learning to highlight FABP4 as a potential therapeutic target.
- * Experimental results showed that treatment with SP can enhance the expression of important skin genes, suggesting its potential role in alleviating symptoms of AD.
