Pituitary adenomas (PA) are commonly occurring benign neoplasms. Identification of molecular pathway resulting in pituitary tumorigenesis remains challenges in endocrine oncology. The present study was conducted with aim of investigating the role of microRNA-543 (miR-543) in PA development. Up-regulated miR-543 and downregulated Smad7 were observed in PA tissues. Afterwards, the specific mechanism of miR-543 and Smad7 in PA were determined with the use of ectopic expression, depletion and reporter assay experiments. Smad7 was confirmed as a target gene of miR-543. HP75 cells treated with overexpressed miR-543 exhibited increased cell proliferation, migration and invasion, while decreased cell apoptosis as well as expression of Cleaved caspase-3 and Cleaved caspase-8 were observed. Suppression of miR-543 contributed to an opposite trend to the above findings. Based on the findings, the inhibition of miR-543 was found to play a tumor suppressive role in PA through the down-regulation of Wnt/β-catenin pathway by negatively regulating Smad7.

Osteosarcoma (OS) is the most common primary malignant bone tumor in childhood. Patients who present with metastatic disease at diagnosis or relapse have a very poor prognosis, and this has not changed over the past four decades. The Wnt signaling pathway plays a role in regulating osteogenesis and is implicated in OS pathogenesis.

Exploration of molecular markers is an ongoing focus in the field of bladder cancer research. Based on data from public databases, was identified as upregulated in bladder urothelial carcinoma (BLCA); however, its exact function and regulatory mechanism in this context remain unclear. To investigate the clinical implications of , we examined its levels in 90 BLCA and adjoining normal tissue samples.

Periodontal disease is recognized as a chronic multifactorial inflammatory condition initiated by dysbiosis within subgingival plaque biofilms. Antimicrobial peptides exhibit a wide spectrum of antimicrobial action, and thus, provide one of the first lines of host defense against oral pathogens. Aged garlic extract (AGE) is effective for preventing the progression of periodontal disease.

Skin, as the body's largest organ, acts as the primary defense mechanism against infection and injury. The maintenance of skin health heavily relies on the regulation of epidermal stem cells, crucial for ensuring epidermal homeostasis, hair regeneration, and the repair of epidermal injuries. Recent studies have placed a growing emphasis on G protein-coupled receptor (GPCR) in the context of understanding epidermal stem cells, uncovering its significant role in determining their fate.
