Purpose: The abnormal activation of the sonic hedgehog (SHH) signaling pathway is responsible for the progression of several types of cancers including Gastric Cancer (GC). SHH has been associated with the activation of different signaling pathways. Therefore, in this study, we investigated messenger RNA (mRNA) and protein expression of SHH in gastric malignancies and possible correlation with various clinicopathological parameters.
Materials And Methods: A total of 53 surgically resected tumors and adjacent histologically normal tissues from GC patients were investigated in study subjects. A quantitative real-time polymerase chain reaction and immunohistochemistry methods were used for expression analysis of SHH.
Results: At mRNA level, SHH was overexpressed in 60% (27/45) of GC cases as compared to their adjacent normal tissues. SHH immunohistochemical analysis revealed abundant cytoplasmic localization and overexpression in 43.39% (23/53) of GC tissues. SHH overexpression was not associated with any of the clinicopathological parameters.
Conclusion: Our results showed that SHH is dysregulated in GC and might be considered as a biomarker for GC progression and can be used as a target in cancer therapeutics.

Purpose: To explore the function of cyclopamine in corneal neovascularization and subsequent fibrosis after cornea alkali-burn injury.
Methods: In vivo, mice cornea were injured by NaOH, and then treated with cyclopamine, clodronate liposomes (CLO-LPS), and vehicle of cyclopamine separately by subconjunctival injections. Clinical features were observed and pathological characteristics were examined.

Sonic Hedgehog (Shh), encoding an extracellular signaling molecule, is vital for heart development. Shh null mutants show congenital heart disease due to left-right asymmetry defects stemming from functional anomaly in the midline structure in mice. Shh signaling is also known to affect cardiomyocyte differentiation, endocardium development, and heart morphogenesis, particularly in second heart field (SHF) cardiac progenitor cells that contribute to the right ventricle, outflow tract, and parts of the atrium.

Aging is a risk factor for several chronic conditions, including intervertebral disc degeneration and associated back pain. Disc pathologies include loss of reticular-shaped nucleus pulposus cells, disorganization of annulus fibrosus lamellae, reduced disc height, and increased disc bulging. Sonic hedgehog, cytokeratin 19, and extracellular matrix proteins are markers of healthy disc.

Background: Neuroinflammatory responses are strongly associated with the pathogenesis of progressive neurodegenerative conditions and mood disorders. Modulating microglial activation is a potential strategy for developing protective treatments for central nervous system (CNS)-related diseases. Fibrates, widely used in clinical practice as cholesterol-lowering medications, exhibit numerous biological activities, such as anticancer and antiinflammatory activities.

The study aimed to understand the impact of the sonic-hedge signal pathway (SHH) on mouse neural stem cells. We manipulated the pathway using purmorphamine (Pur) and Gant 61 and observed the effects on cell viability, neurosphere formation, and gene expression. We found that activating the SHH pathway with Pur increased cell viability, neurosphere formation, and the expression of specific genes, promoting the differentiation of neural stem cells into mature cells.
