Single cell TCR-seq profiling of T cells isolated from LNs of MC38 tumor-bearing mice

Project description:We investigate the single-cell landscape of the inflammatory mouse tumor model MC38, a C57BL/6 tumor cell line derived from colon adenocarcinoma. MC38 (diluted in HBSS and matrigel) was inoculated in the right unilateral flank (in the border of positions B2 and B3) of C57BL/6 mice (ref Study 16-3384 AV). Draining lymph nodes were taken one day after group-out (average 150-250 mm3 tumor size at day 0), approximately 14-19 days. Draining lymph nodes were dissociated and flow sorted accordingly to obtain the cells for 10x Chromium 5' Gene Expression Profiling and TCR sequencing.

RNA Sequencing Analysis of MC38 tumors with Glutamate decarboxylase 1 Knockdown

Project description:Various types of cancers, including colorectal cancer, have shown an unusual dependence on glutamine. Glutamine can undergo an alternate fate in neurons: conversion into a non-proteinogenic amino acid gamma-aminobutyric acid (GABA) by the glutamic acid decarboxylase (GAD), including two family members GAD1 and GAD2. Some studies have shown that GAD1 expression is dysregulated in certain cancer types, but the effect of GAD1 on the tumorigenic process remain largely unknown. Thus, we use mouse colon adenocarcinoma MC38 tumor samples to perform RNA-sequencing (RNA-seq) assay. The goal of this study is to investigate GAD1-mediated transcriptome changes within tumors.

RNA-seq of parental MC38 and anti-PD-1 resistant MC38 subcutaneous tumors

Project description:MC38 tumors resistant to anti-PD-1 treatment (MC38-resistant) were generated through serial in vivo passaging, and global gene expression analysis was used to compare resistant and parental tumors. MC38 and MC38-resistant tumors exhibited widespread changes in global gene expression.

Differential effects of glutamine inhibition strategies on anti-tumor CD8 T cell function

Project description:Activated T cells undergo metabolic reprogramming to meet anabolic, differentiation, and functional demands. Glutamine supports many processes in activated T cells, and inhibition of glutamine metabolism alters T cell function in autoimmune disease and cancer. Multiple glutamine-targeting molecules are under investigation, yet the precise mechanisms of glutamine-dependent CD8 T cell differentiation remain unclear. We show that distinct strategies of glutamine inhibition by glutaminase-specific inhibition with small molecule CB-839, pan-glutamine inhibition with 6-diazo-5-oxo-L-norleucine (DON), or by glutamine deprivation (No Q) produce distinct metabolic differentiation trajectories in CD8 T cells. T cell activation with CB-839 treatment had a milder effect than DON or No Q treatment. A key difference was that CB-839-treated cells compensated with increased glycolytic metabolism, while DON and No Q-treated cells increased oxidative metabolism. However, all glutamine treatment strategies elevated CD8 T cell dependence on glucose metabolism, and No Q treatment caused adaptation toward reduced glutamine dependence. DON treatment reduced histone modifications and numbers of memory-like cells in adoptive transfer studies, but those T cells that persisted could expand normally upon secondary antigen encounter. In contrast, No Q-treated cells persisted well yet demonstrated decreased secondary expansion. Consistent with impaired function, CD8 T cells activated in the presence of DON had reduced ability to control tumor growth and reduced tumor infiltration in adoptive cell therapy. Overall, each approach to inhibit glutamine metabolism confers distinct effects on CD8 T cells and highlights that targeting the same pathway in different ways can elicit opposing metabolic and functional outcomes.
