RNA-Seq analysis of the effect of regorafenib on melanoma cells

ABSTRACT: Melanoma is a malignant tumor with a terrible prognosis. In this study, we showed regorafenib has the ability to limit the growth, invasion and metastasis of melanoma cells but to upregulate apoptosis-prompting markers (cleaved-PARP and Bax). Moreover, ERK/E2F3 signaling influences regorafenib's ability to suppress melanoma cell growth. Ultimately, regorafenib significantly inhibits tumor growth in a dose-dependent manner in vivo.

Role of regorafenib in antitumor immunity in hepatocellular carcinoma

Project description:Low-dose regorafenib (5 mg/kg/day, corresponding to about half of human clinical dosage) inhibited tumor growth and angiogenesis in vivo similarly to DC-101 (anti-VEGFR antibody) but produced higher T cell activation and M1 macrophage polarization, Regorafenib increased M1/M2 ratio of BMDMs polarization and proliferation/activation of co-cultured T cells in vitro, indicating angiogenesis-independent immunomodulatory effects. Suppression of p38 kinase phosphorylation and downstream CREB-KLF4 activity in BMDMs by regorafenib reversed M2 polarization. Regorafenib enhanced antitumor efficacy of adoptively transferred antigen-specific T cells, whereas macrophage deletion negated regorafenib’s antitumor effects. Synergistic antitumor efficacy between low-dose regorafenib and anti-PD1 was associated with multiple immune-related pathways in the tumor microenvironment.

Transcriptomic changes induced by regorafenib in sorafenib-resistant hepatocellular carcinoma cells: role of TGF-beta signaling and lncRNAs

Project description:We comprehensively analyzed the differentially expressed mRNAs (DEmRNAs) and lncRNAs (DElncRNAs) underlying the antitumor functions of regorafenib of sorafenib-resistant HCC cells using RNA sequencing (RNA-Seq). The treatment with regorafenib has demonstrated the ability to reverse the expression of genes and long non-coding RNAs (lncRNAs) that play crucial roles in signal pathways and epigenetic processes.

Spatial SILAC Regorafenib Treated Bottom-up Proteomic Analysis

Project description:Developing effective model systems to evaluate new potential chemotherapeutic reagents is critical. Three-dimensional cell cultures, such as spheroids, aid in bridging the gap between commonly used monolayer cell cultures and significantly more complex and expensive animal models. Spheroid model systems contain pathophysiological and chemical gradients similar to an in vivo tumor, which ultimately form distinct cellular subpopulations. In the spatial SILAC model, labels are pulsed into the spheroid at discrete time windows during development. These media pulses result in labeled proteins in distinct regions of the spheroid, which allows for tracing of quantitative proteomic changes to be correlated to different cellular subregions. In this study, we use the Spatial SILAC model to evaluate the proteomic response of a colon carcinoma spheroid to the multikinase inhibitor Regorafenib. We determined regorafenib to be an effective kinase inhibitor which significantly altered whole spheroid proliferation and resulted in increased apoptosis when the signal was averaged for all cells in the culture. However, when regorafenib treatment is more closely examined among the cellular subpopulations, drastic differences are observed for how the drug impacted the proteome of the necrotic spheroid core and the proliferating outer regions. Whole spheroid and outer region analysis shows that regorafenib treatment inhibited critical pathways such as mTOR signaling, ERK/MAPK signaling, and colorectal cancer metastasis signaling. However, analysis of the core shows that regorafenib had an entirely different effect, including upregulation of MAPK1 and KRAS, possibly indicating drug resistance within these late apoptotic cells. Ultimately, these combinatory studies can be used to further understanding of drug metabolism is different cellular subpopulations and provide valuable information to ultimately improve the accuracy of therapeutic testing.

Effect of regorafenib, anti-PD1, and anti-CD40 agonist in Head and Neck Squamous Cell Carcinoma [HNSCC_model]

Project description:Regorafenib presented an antitumor activity in HNSCC mouse model and delayed the tumorigenesis of the 4NQO-indued oral mouse model. By tumor-infiltration lymphocytes isolation and RNA-seq analysis, the immunity-related function was activated by regorafenib. We approved that regorafenib can determine the macrophage polarization toward M1 inflammatory macrophages by suppressing the production of certain cytokines such as plasminogen activator inhibitor-1 (PAI-I) from tumor cells. Also, Regorafenib suppresses secretion of PAI-1 from ex vivo cultures of human HNSCC organoids.
