EZH2 protects tumor-infiltrating lymphocytes from metabolic-stress induced cell death and exhaustion

Project description:Direct competition between tumor-infiltrating lymphocytes (TIL) and cancer cells for metabolic resources often renders T cells dysfunctional. Here, we report an epigenetic mechanism contributing to the development of metabolic exhaustion in TILs. T cells undergo a loss of the histone methyltransferase EZH2 (Enhancer of Zeste Homolog 2) during tumor infiltration. Using a multi-omics approach, we have defined a mechanism by which EZH2 inhibition leads to mitochondrial dysfunction and the resultant metabolic exhaustion. Reprogramming T cells to express a gain-of-function EZH2 mutant resulted in an enhanced ability of T cells to inhibit tumor growth. Our studies suggest that manipulation of EZH2 in T cells might represent a potential strategy to protect tumor-specific T cells during metabolic stress.

Non-cancerous liver infiltrating lymphocytes of hepatitis C and tumor-infiltrating lymphocytes

Project description:Study goal is to disclose features of gene expressio profile of non-cancerous liver-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas and tumor-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas. Keywords: gene expression profile, non-cancerous liver-infiltrating lymphocytes, tumor-infiltrating lymphocytes, type C hepatitis, hepatocellular carcinoma Non-cancerous liver-infiltrating lymphocytes were obtained by laser capture microdissection from surgically resected liver tissues of 12 type C hepatitis patients with hepatocellular carcinoma. The mRNA was amplified and expression profile was comprehensively analyzed with reference RNA using oligo-DNA chip.

Evaluation of Tumor Infiltrating Lymphocytes in High-Grade Serous Ovarian Cancer

Project description:Tumor infiltrating lymphocytes (TILs) play a significant role in the tumor microenvironment in high-grade serous ovarian cancer (HGSOC). To better understand the interactions and functions of TILs in HGSOC progression, we performed proteogenomic profiling of TILs in 65 tumors collected from 12 HGSOC patients.

Single-cell RNA-seq of tumor-infiltrating lymphocytes in metastatic uveal melanoma

Project description:Metastatic uveal melanoma generally responds poorly to immunotherapy. The aim here was to sequence tumor-infiltrating lymphocytes from uveal melanoma metastases to study their phenotypes and T-cell receptor (TCR) clonotypes. We performed paired single-cell transcriptome and TCR sequencing using the 10x Genomics platform of IL2-expanded tumor-infiltrating lymphocytes from 7 liver and 1 subcutaneous metastasis.
