BackgroundCitrulline post-translational modification of proteins is mediated by protein arginine deiminase (PADI) family members and has been associated with autoimmune diseases. The role of PADI-citrullinome in immune response in cancer has not been evaluated. We hypothesized that PADI-mediated citrullinome is a source of neoantigens in cancer that induces immune response.MethodsProtein expression of PADI family members was evaluated in 196 cancer cell lines by means of indepth proteomic profiling. Gene expression was assessed using messenger RNA data sets from The Cancer Genome Atlas. Immunohistochemical analysis of PADI2 and peptidyl-citrulline was performed using breast cancer tissue sections. Citrullinated 12–34-mer peptides in the putative Major Histocompatibility Complex-II (MHC-II) binding range were profiled in breast cancer cell lines to investigate the relationship between protein citrullination and antigen presentation. We further evaluated immunoglobulin-bound citrullinome by mass spectrometry using 156 patients with breast cancer and 113 cancer-free controls.ResultsProteomic and gene expression analyses revealed PADI2 to be highly expressed in several cancer types including breast cancer. Immunohistochemical analysis of 422 breast tumor tissues revealed increased expression of PADI2 in ER− tumors (p<0.0001); PADI2 protein expression was positively correlated (p<0.0001) with peptidyl-citrulline staining. PADI2 expression exhibited strong positive correlations with a B cell immune signature and with MHC-II-bound citrullinated peptides. Increased circulating citrullinated antigen–antibody complexes occurred among newly diagnosed breast cancer cases relative to controls (p=0.0012).ConclusionsAn immune response associated with citrullinome is a rich source of neoantigens in breast cancer with a potential for diagnostic and therapeutic applications.

Aims and Objectives: To report a series of cases with breast and ovarian carcinomas either in same patient or in a family and identifying the importance of BRCA 1,2 genetic testing in such individuals. Materials and Methods: The medical records of breast and ovarian cancer patients operated over past 3 years at a single institute were reviewed retrospectively and their clinical profile, family history, final pathological reports and follow up data was collected. Results: 8 patients were found to have breast and ovarian malignancies, out of which 3 had synchronous breast and ovarian cancers, 4 had metachronous and 1 patient with ovarian cancer had history of breast cancer in family. Median age of presentation to the hospital was 47 years and median time interval in metachronous disease patients was 5.5 years. Conclusion: About 5% of people who have breast cancer and about 10% of women who have ovarian cancer have HBOC, caused by germline mutation in BRCA1, 2 gene. These individuals have increased risk of developing breast cancer at younger age, TNBC, or developing a second primary in breast or ovary plus an overall risk of breast/ovarian/prostate/pancreatic malignancies in other family members due to inheritable mutation. Identification of BRCA mutation in such individuals can help family members to undergo genetic counseling and follow different screening and prevention guidelines from general population thus reducing the cancer risks.
