Inflammatory fibroblasts mediate resistance to neoadjuvant therapy in rectal cancer

Cancer Cell, Journal Year: 2022, Volume and Issue: 40(2), P. 168 - 184.e13

Published: Feb. 1, 2022

Standard cancer therapy targets tumor cells without considering possible damage on the microenvironment that could impair response. In rectal patients we find inflammatory cancer-associated fibroblasts (iCAFs) are associated with poor chemoradiotherapy Employing a murine model or patient-derived organoids and primary stroma cells, show that, upon irradiation, interleukin-1α (IL-1α) not only polarizes toward phenotype but also triggers oxidative DNA damage, thereby predisposing iCAFs to p53-mediated therapy-induced senescence, which in turn results resistance disease progression. Consistently, IL-1 inhibition, prevention of senolytic sensitizes mice while lower receptor antagonist serum levels correlate prognosis. Collectively, unravel critical role for identify signaling as an attractive target stroma-repolarization senescence.

Signaling pathways in cancer‐associated fibroblasts: recent advances and future perspectives

Cancer Communications, Journal Year: 2022, Volume and Issue: 43(1), P. 3 - 41

Published: Nov. 24, 2022

As a critical component of the tumor microenvironment (TME), cancer-associated fibroblasts (CAFs) play important roles in cancer initiation and progression. Well-known signaling pathways, including transforming growth factor-β (TGF-β), Hedgehog (Hh), Notch, Wnt, Hippo, nuclear factor kappa-B (NF-κB), Janus kinase (JAK)/signal transducer activator transcription (STAT), mitogen-activated protein (MAPK), phosphoinositide 3-kinase (PI3K)/AKT as well factors, hypoxia-inducible (HIF), heat shock 1 (HSF1), P53, Snail, Twist, constitute complex regulatory networks TME to modulate formation, activation, heterogeneity, metabolic characteristics malignant phenotype CAFs. Activated CAFs remodel influence biological processes cells by altering transcriptional secretory characteristics, this modulation partially depends on regulation cascades. The results preclinical clinical trials indicated that therapies targeting pathways demonstrated promising efficacy but were also accompanied some failures (e.g., NCT01130142 NCT01064622). Hence, comprehensive understanding cascades might help us better understand progression may facilitate development more efficient safer stroma-targeted therapies. Here, we review recent advances studies briefly discuss future perspectives CAF research.

Abstract Background The tumor-promoting role of tumor microenvironment (TME) in colorectal cancer has been widely investigated biology. Cancer-associated fibroblasts (CAFs), as the main stromal component TME, play an important promoting progression and metastasis. Hence, we explored crosstalk between CAFs pathogenesis order to provide basis for precision therapy.

Role of Epithelial to Mesenchymal Transition in Colorectal Cancer

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(19), P. 14815 - 14815

Published: Oct. 1, 2023

The epithelial–mesenchymal transition (EMT) is a cellular reprogramming process that occurs during embryonic development and adult tissue homeostasis. This involves epithelial cells acquiring mesenchymal phenotype. Through EMT, cancer acquire properties associated with more aggressive EMT its opposite, mesenchymal–epithelial (MET), have been described in tumors over the past ten years, including colorectal (CRC). When activated, expression of marker E-cadherin decreased vimentin raised. As result, temporarily take on phenotype, becoming motile promoting spread tumor cells. Epithelial–mesenchymal plasticity (EMP) has become hot issue CRC because strong inducers (such as transforming growth factor β, TGF-β) can initiate regulate metastasis, microenvironment, immune system resistance CRC.

Colorectal Cancer Organoid–Stroma Biobank Allows Subtype-Specific Assessment of Individualized Therapy Responses

Cancer Discovery, Journal Year: 2023, Volume and Issue: 13(10), P. 2192 - 2211

Published: July 25, 2023

In colorectal cancers, the tumor microenvironment plays a key role in prognosis and therapy efficacy. Patient-derived organoids (PDTO) show enormous potential for preclinical testing; however, cultured cells lose important characteristics, including consensus molecular subtypes (CMS). To better reflect cellular heterogeneity, we established cancer organoid-stroma biobank of matched PDTOs cancer-associated fibroblasts (CAF) from 30 patients. Context-specific phenotyping showed that xenotransplantation or coculture with CAFs improves transcriptomic fidelity instructs subtype-specific stromal gene expression. Furthermore, functional profiling exposed CMS4-specific therapeutic resistance to gefitinib SN-38 prognostic expression signatures. Chemogenomic library screening identified patient- therapy-dependent mechanisms MET as common target. Our results demonstrate phenotypes are encrypted epithelium plastic fashion strongly depends on context. Consequently, essential faithful representation responses ex vivo. Systematic characterization provides resource context dependency cancer. We subtype memory is independent specific driver mutations. data underscore importance cocultures improved testing identification mechanisms. This article featured Selected Articles Issue, p. 2109.
