Profiling CARD14 gene expression in Indian Psoriasis patients

Area of Science:

• Genetics
• Dermatology
• Molecular Biology

Background:

• Psoriasis is a chronic inflammatory skin condition with a complex genetic basis.
• Genome-Wide Linkage Studies have identified several susceptibility loci for psoriasis.
• Caspase Recruitment Domain-containing family 14 (CARD14) is a key regulator of the NF-kB signaling pathway, implicated in skin inflammation.

Purpose of the Study:

• To investigate the role of CARD14 gene expression in Indian patients with plaque psoriasis.
• To explore the potential functional consequences of CARD14 dysregulation in psoriasis pathogenesis.
• To correlate CARD14 expression levels with disease severity in an Indian cohort.

Main Methods:

• Quantitative Polymerase Chain Reaction (qPCR) was used to analyze CARD14 gene expression in lesional skin samples.
• Immunohistochemistry (IHC) was employed for validation of CARD14 expression in different cell types.
• Gene expression data from Western populations were used for comparative analysis.

Main Results:

• A significant two-fold up-regulation of CARD14 expression was observed in lesional tissues of Indian psoriasis vulgaris patients compared to controls.
• CARD14 expression was identified in dermal endothelial cells of psoriatic patients.
• The findings were consistent with CARD14 expression patterns observed in Western populations.

Conclusions:

• CARD14 up-regulation is significantly associated with psoriasis in the Indian population.
• The study highlights CARD14's role in the pathogenesis of psoriasis, particularly its expression in dermal endothelial cells.
• These findings contribute to understanding the genetic architecture and molecular mechanisms underlying psoriasis.
