Extrahepatic tumors induce inflammation causing liver depletion of HNF4a and driving a systemic metabolic rewiring

ABSTRACT: To evaluate whether liver metabolic pathways are affected by non-hepatic cancer in-vivo, we performed RNA sequencing of hepatocytes isolated from perfused livers of WT and 4T1 breast cancer-bearing mice on days 4 and 21 following cancer cells injection.

Pre-metastatic expression array day 7

Project description:To follow the earliest transcriptional changes in pre-metastatic tissues, we orthotopically injected 4T1 cells into the mammary fat pad of female nude mice. Control mice were orthotopically injected with PBS. 7 days post tumor engraftment, the mice were sacrificed and thoroughly perfused with ice cold PBS, and lung and liver samples were flash frozen in liquid nitrogen. Following RNA extraction, the lung and liver RNA samples were analyzed on MOE430A2 Affymetrix arrays using R/Bioconductor software. Expression array was performed on lung or liver tissue from control or tumor-bearing mice. Lung and liver tissues were isolated from 3 control mice (injected with PBS) and 3 tumor-bearing mice (injected with 4T1 cells) 7 days post injection.

Extracellular vesicles and particles derived from tumors with extrahepatic metastatic tropism induce liver dysregulation

Project description:Cancer is a systemic disease that includes several noted features, such as pre-metastatic niche formation, cachexia, and immune dysregulation. However, the mechanisms underlying multi-organ failure remain to be further investigated. Here, we show that inflammation, fatty liver, and dysregulated metabolism are hallmarks of systemically affected livers in various animal tumor models and cancer patients in the absence of hepatic metastasis. We identify that tumor-derived extracellular vesicles and particles (EVPs) are crucial mediators of cancer-induced hepatic functional reprogramming. Tumor EVPs package multiple fatty acids, such as palmitic acid, and target Kupffer cells upregulating tumor necrosis factor alpha (TNFα) via Toll-like receptor 4 (Tlr4), which in turn promotes a pro-inflammatory microenvironment leading to fatty liver formation and downregulates metabolic pathways, such as fatty acid metabolism and oxidative phosphorylation. Strikingly, ablation of Kupffer cells or TNFα blockade markedly abrogates the tumor-induced excess hepatic lipid droplet accumulation. We show that tumor implantation or pre-treatment with tumor EVPs decreases the expression of Cytochrome P450 genes and attenuates drug metabolism in mice. Notably, increased fatty livers and decreased Cytochrome P450 genes are observed in tumor-free livers in cancer patients. Thus, tumor-derived EVP uptake in the liver may lead to reduced tolerance of drug toxicity in cancer patients. Our results highlight the role of tumor EVPs in dysregulating hepatic functions and its potential to serve as therapeutic targets along with Kupffer cell-induced TNFα inhibition to prevent fatty liver formation and enhance anti-cancer chemotherapy.

Identification of a Highly Immunogenic Mouse Breast Cancer Sub Cell Line, 4T1-S

Project description:Recently, cancer immunotherapy has been paid much attention because of its improved efficacy and low frequency of adverse effects. A mouse breast cancer cell line, 4T1, has been known as poorly immunogeneic and highly metastatic cell line. In this study, we have identified a sub cell line of 4T1, designated as 4T1-Sapporo (4T1-S), which could induce a strong immune response against the same line. When 4T1-S was subcutaneously injected, striking enlargement of draining lymph nodes and increase of activated T cells were observed. The strong immune responses could not be observed when 4T1-S was injected to nude mice, indicating that this phenomenon is mediated by T cell response. Identification of 4T1-S characteristics may help to improve immunotherapy against breast cancer. 4T1-A1, 4T1-A2, 4T1-S1, 4T1-S2

Genetic Screens Identify a Context-Specific PI3K/p27Kip1 Node Driving Extrahepatic Biliary Cancer.

Project description:Biliary tract cancer ranks among the most lethal human malignancies, representing an unmet clinical need. Its abysmal prognosis is tied to an increasing incidence and a fundamental lack of mechanistic knowledge regarding the molecular basis of the disease. Here, we show that the Pdx1-positive extrahepatic biliary epithelium is highly susceptible toward transformation by activated PIK3CAH1047R but refractory to oncogenic KrasG12D. Using genome-wide transposon screens and genetic loss-of-function experiments, we discover context-dependent genetic interactions that drive extrahepatic cholangiocarcinoma (ECC) and show that PI3K signaling output strength and repression of the tumor suppressor p27Kip1 are critical context-specific determinants of tumor formation. This contrasts with the pancreas, where oncogenic Kras in concert with p53 loss is a key cancer driver. Notably, inactivation of p27Kip1 permits KrasG12D-driven ECC development. These studies provide a mechanistic link between PI3K signaling, tissue-specific tumor suppressor barriers, and ECC pathogenesis, and present a novel genetic model of autochthonous ECC and genes driving this highly lethal tumor subtype.SignificanceWe used the first genetically engineered mouse model for extrahepatic bile duct carcinoma to identify cancer genes by genome-wide transposon-based mutagenesis screening. Thereby, we show that PI3K signaling output strength and p27Kip1 function are critical determinants for context-specific ECC formation. This article is highlighted in the In This Issue feature, p. 2945.

Label-free LC-MS/MS of Ubiquitinated proteins derived from UPs-4T1/WT and UPs-4T1/EPB nanovaccine

Project description:In this project, 4T1 parental cells (4T1/WT) were exposed to increasing concentrations of epirubicin (EPB) to establish a novel multi-drug resistant CSC-like breast cancer cell line (4T1/EPB). The ubiquitinated proteins were enriched from 4T1/WT or 4T1/EPB derived cell lysate using a-Al2O3-Vx3 nanoparticles to produce the covalently linked product UPs nanovaccine. Label-free LC-MS/MS mass spectrometry was used to detect the type and amount of enriched proteins of UPs from the 4T1/WT cells and the 4T1/EPB cells.

Expression data from adult mice breast cancer cell 4T1

Project description:Microaaray data for CD44v8-10-positive / CD44v8-10-negative 4T1 cancer cells (mouse breast cancer cells) We used microarrays to detail the global programming of gene expression of 4T1 cells depending on whether CD44v is present or not. 4T1 cells, one of the mouse breast cancer cells, were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the data about to which extent gene expression profile is different between CD44v-positive and CD44v-negative 4T1 cancer cells.
