First evidence: Parkinson's and Alzheimer's disease caused by fungi
Enhancement of melanoma aggressiveness via p38-MAPK, HIF-1α pathways, and metabolic reprogramming induced by Candida albicans
(Scientific Reports, 2026;
doi: 10.1038/s41598-025-24055-y) Quelle: Scientific Reports, University of the Basque Country Recent studies have increasingly focused on the role of fungi,
including Candida albicans, in carcinogenesis. Since C.
albicans is a component of the human microbiota, particularly on the
skin, we investigated its effect on the phenotype and signalling
pathways of melanoma cells. Assays for migration, adhesion,
angiogenesis, and hepatic metastasis showed that C. albicans
promotes a more malignant phenotype in melanoma cells. At the
transcriptomic level, C. albicans increased the expression of
VEGF (Vegfa), and genes associated with MAPK and HIF-1 signalling
pathways, and with aerobic glycolysis. Further in vitro analysis
revealed that TLRs and EphA2 receptors are involved in the recognition
of live C. albicans, stimulating VEGF secretion and expression of
the AP-1 transcription factor component c-Fos through p38-MAPK and
HIF-1α. These pathways also regulate the expression of other AP-1
constituents such as Atf3, Jun, and Jund. Moreover,
p38-MAPK regulates glycolytic genes like Hk2, Slc2a1, and
Eno2. In conclusion, C. albicans activates the p38-MAPK/c-Fos/AP-1
and HIF-1/HIF-1α/c-Fos/AP-1 pathways in melanoma cells, promoting a pro-angiogenic
environment and metabolic reprogramming. Therefore, this study clarifies
the impact of C. albicans on melanoma cells, which can lead to
the use of antifungal therapies as complementary to traditional
treatments for melanoma.
