Various studies suggested that cytotoxicity induced by 5-fluorouracil (5-FU) is an apoptotic mechanism possibly mediated by the Fas/FasL system. In this preliminary work, we studied retrospectively the role the Fas/FasL expression as a predictive response factor with fluoropyrimidine-based chemotherapies. We developed a real-time PCR method for measuring Fas and FasL expression in various biopsies from patients treated with a FUFOL-like protocol. No correlation was found between Fas or FasL expression and overall survival or partial response. However, the PCR assay was simple and convenient to use for quantitation of Fas/FasL in tumor biopsies.

Receptors for advanced glycation end products (RAGE) are multiligand cell surface receptors found most abundantly in lung tissue. This study sought to evaluate the role of RAGE in lung development by using a transgenic (TG) mouse model that spatially and temporally controlled RAGE overexpression. Histological imaging revealed that RAGE upregulation from embryonic day (E) 15.

Background: Colorectal cancer (CRC) is one of the most prevalent cancers worldwide. Despite advancements in therapeutic methodologies, it still causes a high rate of patient mortality. CD8 tissue-resident memory T (TRM) cells are strategically positioned to mediate effective anti-tumor responses.

Background: Alveolar soft-part sarcoma (ASPS) is a rare tumor driven by the ASPSCR1-TFE3 fusion protein, with a propensity for metastasis. Prognostic factors remain poorly understood, and traditional chemotherapies are largely ineffective. Recent interest lies in immune checkpoint inhibitors (ICIs), yet predictive biomarkers for treatment response are lacking.

Immune privilege is the ability to tolerate foreign antigens without eliciting an inflammatory immune response. Several mechanisms explain a structure's immune privilege status, which is regulated by innate and adaptive immune responses. The role of myofibroblasts in perpetuating fibrosis by acquiring an immune privileged phenotype against the backdrop of oral submucous fibrosis (OSF) is evolving.
