Objective: This study aimed to analyze the predominant expression of the variable region of T cell receptor (TRBV) and determine whether NAV3 or TNFRSF1B gene mutation involved in the pathogenesis of MF.
Results: TRBV5-7 expression increased from the normal, early-stage to advanced-stage lesion in MF patient. By contrast, TRBV2 decreased with the lesion developed. We found no mutations of NAV3 or TNFRSF1B in the lesions from this study.
Materials and Methods: Real-time PCR were used to screen differential expression of TRBV in different lesions. Mutational analyses were used to validate genetic alterations in the skin lesions.
Conclusions: The identification of TRBV gene expression differences between normal and different stages of MF lesions provide insight into promising new diagnostic and prognostic biomarkers. None of the reported genetic abnormalities suggests complexity of progress from a primary cytogenetic event to an advanced stage with poor prognosis in MF.
