Fanconi anemia: matrix remodeling and oral carcinogenesis

Listed in NCBI GEO

Fanconi anemia (FA) increases the risk of early-onset oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma; however, the earliest stromal determinants of malignant progression remain undefined.

Description

We investigated whether extracellular matrix (ECM) remodeling constitutes an initial and quantifiable hallmark of FA-associated OPMD. A total of 119 participants were included: controls with normal mucosa or oral leukoplakia (OL) and individuals with FA.

Histopathology, immunohistochemistry (p53, Ki-67, α-SMA, elastin), picrosirius red staining, and multiphoton microscopy combining second-harmonic generation and two-photon fluorescence were performed, complemented by salivary and transcriptomic profiling. Additionally, FANCA/p53EPI and p53 murine models were used to assess stromal remodeling. Compared with sporadic OL, FA-OL exhibited reduced collagen density and elastin autofluorescence, higher collagen-to-elastin ratio, and diminished p53 expression.

Salivary procollagen type 1 N-terminal propeptide declined and correlated with matrix-derived optical parameters. RNA sequencing revealed upregulated ECM structural genes and downregulated ECM regulators in FA patients. In FA-mimicking mice, collagen and elastin signals progressively decreased.

Collectively, multimodal imaging and transcriptomic data unveil ECM disruption as a defining feature of FA-OL. Matrix disorganization, coupled with epithelial p53 loss delineates a permissive stromal niche that links genomic instability to malignant transformation.
