Microarray gene expression profiles of peripheral blood mononuclear cells in patients with advanced stage non-small cell lung cancer treated with first line combination chemotherapy with or without Rikkunshito treatment

ABSTRACT: We have extended our investigation to advanced-stage NSCLC by analyzing gene expression in peripheral blood mononuclear cells (PBMC) from patients with newly-diagnosed NSCLC and histopathology of either AC or SCC. Furthermore, to establish a direct link between gene expression and chemotherapy treatment, PBMC from patients who have received 4 courses of combination chemotherapy with CDDP and GEM, or combination chemotherapy plus Rikkunshito were obtained, and the effects of Rikkunshito during chemotherapy on global gene expression were evaluated using microarray analyses. We analyzed microarray gene expression profiles of peripheral blood mononuclear cells from 17 patients with newly-diagnosed advanced stage NSCLC, and 20 age, sex, and co-morbidity-matched healthy controls (HC). All the cancer patients received a maximum of six courses of chemotherapy with cisplatin and gemcitabine of a 28-day cycle as first line treatment. Furthermore, to establish a direct link between gene expression and Rikkunshito treatment, PBMC from patients who have received 4 courses of combination chemotherapy with CDDP and GEM puls Rikkunshito (9 pateints) or dry powder placebo (8 patients) were obtained, and the effects of chemotherapy on global gene expression were evaluated using microarray analyses.

We analyzed microarray gene expression profiles of peripheral blood mononuclear cells from 30 patients with newly-diagnosed advanced stage NSCLC, and 20 age, sex, and co-morbidity-matched healthy controls (HC).

microRNA microarray on a cohort study of platinum-sensitive versus platinum-resistant NSCLC patients

Project description:To identify microRNAs that regulate therapeutic resistance, we conducted a high-throughput miRNA microarray on a cohort study of primary NSCLC (non-small cell lung cancer) tissues and adjacent normal tissues. We found some microRNAs related to therapeutic resistance and poor prognosis. In this study, the patients who were diagnosed with resected NSCLC (adenocarcinoma or squamous cell carcinoma) were enrolled. All tumors were reviewed by pathologists and were pathologically diagnosed according to the World Health Organisation Classification of Tumors. Twenty-nine patients who received four or more courses of first-line platinum-based chemotherapy after postoperative recurrence were divided into two groups (responder (n=17) and non-responder group (n=12)). As identified by ANOVA analysis and quantitative RT-PCR (qRT-PCR) of 4 groups, some miRNAs exhibited significant expression changes.

Predictors of depression in breast cancer patients during and after radiotherapy: Role of chemotherapy and the inflammatory response

Project description:Chemotherapy and the inflammatory response were associated with persistent depressive symptoms in breast cancer patients undergoing radiation. Treatments targeting inflammation before radiation may reduce depression post radiation therapy, especially in patients who have been treated previously with chemotherapy. Total RNA was isolated from the peripheral blood mononuclear cells (PBMC) obtained from the women (n=61) with Stage 0-III breast cancer treated with or without chemotherapy.

MEK inhibition overcomes chemoimmunotherapy resistance by inducing CXCL10 in cancer cells [France4]

Project description:Chemotherapy with anti PD-1/PD-L1 mAb has become the standard of care for patients with metastatic non-small cell lung cancer (NSCLC). Using lung tumor models, where pemetrexed-platinum chemotherapy (PEM/CDDP) remains unable to synergize with immune checkpoint inhibitors (ICI), we linked failure of this treatment with its inability to induce CXCL10 expression and CD8+ T cell recruitment. Using drug screening, we showed that combining a MEK inhibitor (MEKi) with PEM/CDDP triggers CXCL10 secretion by cancer cells and CD8+ T cell recruitment, and restores ICI efficacy. PEM/CDDP plus MEKi promotes optineurin (OPTN)-dependent mitophagy, resulting in CXCL10 production in a mitochondrial DNA and TLR9-dependent manner. TLR9 or autophagy/mitophagy processes genetic inactivation of abort the antitumor efficacy of PEM/CDDP plus MEKi/anti PD-L1 therapy. In human NSCLC, high OPTN, TLR9 and CXCL10 expression is associated with better response to ICI. Our results underline the role of TLR9 and OPTN-dependent mitophagy in enhancing chemoimmunotherapy efficacy.

miRNA profiling of longitudinal ovarian cancer biopsies collected before and after platinum-based neo-adjuvant chemotherapy

Project description:In the last decades platinum-based neo-adjuvant chemotherapy (NACT) has been recognized as a reliable therapeutic strategy in patients with un-resectable advanced epithelial ovarian cancer (EOC). However, the molecular changes induced by NACT at miRNA level, and their prognostic role has not been clarified until now. In order to uncover miRNAs that are altered in EOC tumor which received NACT, we performed whole-miRNA analysis on 82 FIGO Stage IIIC-IV high-grade serous (HGS) tumors, whose samples had been collected at complete primary debulking (PDS) and at interval-debulking surgery (IDS) after fter 4 courses of NACT.

Identification of proteome changes in apoptotic NSCLC cells

Project description:Here, we used an unbiased, functional target-discovery platform to identify immunogenic proteins from primary non-small cell lung cancer (NSCLC) cells that had been induced to apoptosis by cisplatin (CDDP) treatment in vitro, as compared with their live counterparts. Among the multitude of proteins identified, some of them were represented as fragmented proteins in apoptotic tumor cells, and acted as non-mutated neoantigens. Only the fragmented proteins elicited effective multi-specific T cell responses, upon a chemotherapy protocol including CDDP. Importantly, these responses further increased significantly upon anti-PD-1 therapy, and correlated with patients’ survival and decreased PD-1 expression.
