TL;DR

Conservation of SAA1-TLR4 signaling in human skeletal muscle identifies a therapeutically actionable tumor–host pathway and demonstrates that host deterioration can be targeted independently of tumor progression.

Abstract A062: SFRP2 Silencing Restrains Pancreatic Cancer Growth and Enhances Survival Through Remodeling of the Tumor Microenvironment

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with limited therapeutic options. Secreted frizzled-related protein 2 (SFRP2) has emerged as an important mediator of tumor progression by promoting tumor cell survival, immune exhaustion, and angiogenesis. In human PDAC, elevated SFRP2 expressio...

Abstract B101: Stroma-tumor crosstalk converges with oncogenic KRAS signaling to drive an NFκB-mediated immune evasion program

An immunosuppressive tumor microenvironment (TME) is a hallmark of pancreatic ductal adenocarcinoma (PDAC), rendering most tumors resistant to immunotherapy approaches. Importantly, “tumor-to-stroma” crosstalk downstream of oncogenic KRAS has emerged as a major driver of immune evasion in PDAC, however the role of re...

Abstract B001: Cancer-associated fibroblast p38α MAPK signaling coordinates collagen architecture and immune suppression to drive chemoresistance in pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC) remains highly refractory to chemoimmunotherapy due in large part to its dense, immunosuppressive stroma. Cancer-associated fibroblasts (CAFs), the dominant stromal cell population, promote tumor progression through inflammatory signaling, aligned collagen-rich extracellula...

Abstract B099: Tumor progression locus 2 kinase drives pancreatic cancer immune evasion through a MYBL2-CXCL10 signaling axis

Pancreatic ductal adenocarcinoma (PDAC) is characterized by a chronically inflamed tumor microenvironment (TME) driven by persistent activation of innate inflammatory signaling. Tumor progression locus 2 (TPL2; MAP3K8) is a serine/threonine kinase downstream of KRAS that activates both MAPK and NF-κB signaling; howev...

A microbial chromatin remodeler drives gastric cancer progression and immune evasion by reprogramming the host epigenome.

First-line treatment for gastric cancer (GC) includes PD-1 blockade with chemotherapy, but resistance challenges treatment success. We identify Streptococcus anginosus (SA) as a tumor-resident oncobacterium driving GC progression and immune evasion. SA is enriched in GC patient tumors and drives tumor growth in mice. S...
