TP53 and pancreatic neoplasm: As mentioned above, there is also great concern about the risk of dysfunction in the crucial cancer suppressor genes, brca2 and P53, as well as BRCA1, through mechanisms involving downregulation of IRF9 through interference by specific miRNA in exosomes [26] and the possible sequestration by the S2 subunit of S-protein in the vaccine [91]. Impaired BRCA1 activity is associated with higher risk of breast, uterine, and ovarian cancer in women and prostate cancer in men, as well as moderately higher risk of pancreatic cancer in both men and women [92].
