Purpose: We recently reported that SART3 tumor rejection antigen is recognized by HLA class I restricted cytotoxic T lymphocytes from patients with esophageal cancer. We now investigate the expression of SART3 antigen in renal cell carcinoma to identify an appropriate molecule that may be used in specific immunotherapy of renal cell carcinoma.
Materials And Methods: Renal cell carcinoma and nontumorous kidney tissues were obtained at surgery. A section of each sample was minced with scissors and stored at -80C until use. SART3 antigen expression was examined in uncultured renal cell carcinoma and nontumorous kidney tissues. We also evaluated the ability of derived peptides to include cytotoxic T lymphocytes in peripheral blood mononuclear cells from patients with renal cell carcinoma.
Results: The SART3 antigen was detected in all renal cell carcinoma cell lines, primary cultures of renal cell carcinoma and nontumorous kidney tissues, and in the cytosol of 57% and 15% of renal cell carcinoma and nontumorous kidney tissues, respectively. HLA-A2402 restricted and tumor specific cytotoxic T lymphocytes (KE4) used in cloning of the SART3 gene were significantly cytotoxic to cells from renal cell carcinoma cell lines and primary cultures of renal cell carcinoma tissue but they did not lyse normal cells, including those from primary cultures of nontumorous kidney tissue. The SART3 peptides derived from positions 109-118 and 315-323 induced HLA-A24 restricted cytotoxic T lymphocytes to renal cell carcinoma cells from peripheral blood mononuclear cells of patients with renal cell carcinoma.
Conclusions: The SART3 antigen and derived peptides may be applied to the specific immunotherapy of HLA-A24+ renal cell carcinoma.

Background: Clear cell renal cell carcinoma (ccRCC) has a high incidence rate and poor prognosis, and currently lacks effective therapies. Recently, peptide-based drugs have shown promise in cancer treatment. In this research, a new endogenous peptide called CBDP1 was discovered in ccRCC and its potential anti-cancer properties were examined.

This study is designed to assess the effect of root extract of P. ginseng on kidney tissue injury attributed to cisplatin and its molecular mechanism involved in this process in the AKI rat model. Twenty-four male Wistar rats were randomly allocated into 4 experimental groups including: the control group, the cisplatin group, the extract 100 mg/kg group, and the extract 200 mg/kg group.

Clear cell renal cell carcinoma is a prevalent urological malignancy, imposing substantial burdens on both patients and society. In our study, we used bioinformatics methods to select four putative target genes associated with EMT and prognosis and developed a nomogram model which could accurately predicting 5-year patient survival rates. We further analyzed proteome and single-cell data and selected PLCG2 and TMEM38A for the following experiments.

Sepsis is a systemic inflammatory response to infection, and its occurrence is associated with a poor prognosis in the context of multiorgan dysfunction syndrome (MODS). Although there are several animal models for the study of its etiology, the cecal ligation and puncture (CLP) model has been considered the "Gold standard" because it shows a high degree of similarity to the progression of human sepsis. Currently, it is one of the most frequently chosen options to search for therapeutic alternatives to diminish the progression and organ damage induced by sepsis.

Combined blockade of the immune checkpoints PD-1 and CTLA-4 has shown remarkable efficacy in patients with melanoma, renal cell carcinoma, non-small-cell lung cancer and mesothelioma, among other tumor types. However, a proportion of patients suffer from serious immune-related adverse events (irAEs). In severe cases, a reduction of the doses or the complete cessation of the treatment is required, limiting the antitumor efficacy of these treatments.
