Fruquintinib as a Maintenance Therapy Following First-line Treatment for Metastatic Colorectal Cancer

ABSTRACT: This study was a randomized, controled, multicenter, phase II clinical study evaluating the efficacy and safety of fruquintinib as a maintenance therapy following first-line treatment for metastatic colorectal cancer. This study will include the patients with confirmed unresectable metastatic left-sided colon cancer with RAS mutation or right-sided colon cancer who achieved stable disease (SD) or partial response (PR) or complete response (CR) via palliative first-line treatment. It’s expected to include 110 patients and they will be randomly stratified at 2:1 into fruquintinib group and observation group based on whether bevacizumab is used and the primary tumor site, using the Interactive Network Response System (IWRS). The random No. corresponds to the respective patient. The enrollment time is expected to be 18 months, followed up for 24 months.

serum exosomes contain SPARC and LRG1 as biomarkers for colon cancer and differ by tumor primary location

Project description:Purpose: Over the past few years, the distinction between left- and right-sided colon cancer has been brought into focus. Right-sided tumor location was associated with an inferior overall survival and progression-free survival. We aimed to perform a detailed analysis of the diversity in exosomes between left- and right-sided colon cancer using quantitative proteomics. Experimental Design: We isolated exosomes from left- and right-sided colon cancer patients and healthy volunteers and treated colorectal cancer cell line with serum-derived exosomes. Then we performed quantitative proteomics analysis of the serum-derived exosomes and cell line treated with exosomes, respectively. Results: The expression profile of the serum exosome proteome in patients with right-sided colon cancer is different from patients with left-sided colon cancer. Serum-derived exosomes of right-sided colon cancer promote metastasis via up-regulation of extracellular matrix-related proteins, especially proteoglycans like SPARC and glycoprotein like LRG1. Exosomal SPARC and LRG1 were closely correlated with progression-free survival. Conclusions: Proteomic analysis identified different exosomal protein profiling between left- and right-sided colon cancer. Serum-derived exosomes of right-sided colon cancer promote metastasis via overexpression of SPARC and LRG1.

KBM7 genetrap mutant cells stimulated with TNF-alpha and IFN-gamma

Project description:Transcriptional response of KBM7 cells to IFN-gamma or TNF-alpha was investigated in control or cells with genetrap insertions in JAK2 or TNFRS1A, respectively. The experiment shows that, as expected, cells lacking JAK2 or TNFRS1A expression display a severly blunted response to the tested cytokines. KBM7 genetrap mutant cells stimulated with TNF-alpha and IFN-gamma Sample WT_1 corresponds with the control sample for the IFN-gamma stimulation; Sample WT_2 corresponds with the control sample for the TNF-alpha stimulation. As the expected differences between the samples was large, only single replicates were performed for each condition

What is the transcriptomic contrast between a TDNA-mutant and its respective wild-type from young Arabidopsis rosette?

Project description:ra15-07_burxcol_465 - burxcol-465 - What is the transcriptomic contrast between a TDNA-mutant and its respective wild-type from young rosette grown in precisely-controlled conditions on our phenotyping robot (Phenoscope)? - The candidate gene (AT1G36310) was identified through QTL mapping and cloning for rosette leaf growth trait in a Bur x Col RIL set. It corresponds to a medium effect on growth and a major effect on other traits (leaf colour and pigments). We are now exploiting an independent TDNA-insertion line (SALK_135308) in the Col-0 background) to study its effect in a simple genetic context. This is a simple comparison between homozygous T-DNA (2 lines) and their respective WT (2 lines).

Tislelizumab Plus Cetuximab and Irinotecan vs Third-line Standard-of-care in Refractory mCRC

Project description:This is a multicenter, randomized, controlled, phase II study to evaluate the efficacy and safety of tislelizumab combined with cetuximab and irinotecan（group A） compared to third-line regimens selected by researchers（group B） in the treatment of Ras wild-type recurrent and refractory metastatic colorectal cancer. This study will include Ras wild-type colorectal cancer that failed at least second-line treatment inthe past, including chemotherapy (oxaliplatin, irinotecan, fluorouracil) with or without targeted drugs (cetuximab, bevacizumab). 87 patients will be randomly assigned to group A and group B according to 2:1. The enrollment time is expected to be 12 months and the follow-up is expected to be 24 months.

Resolving the Difference Between Left-sided and Right-sided Colorectal Cancer by Single-cell Sequencing

Project description:Colorectal cancers (CRCs) exhibit differences in incidence, pathogenesis, molecular pathways and outcome depending on the location of the tumor. The transcriptomes of 27,927 single human CRC cells, from three left-sided and three right-sided CRC patients were profiled by scRNA-seq. Right-sided CRC harbors a significant proportion of exhausted CD8 T cells of a highly migratory nature. One cluster of cells from left-sided CRC exhibiting states preceding exhaustion and a high ratio of “pre-exhausted” to exhausted T cells were favorable prognostic markers. Notably, we identified a novel RBP4+ NTS+ subpopulation of cancer cells that exclusively expands in left-sided CRC. Tregs from left-sided CRC showed higher levels of immunotherapy-related genes than those from right-sided CRC, indicating that left-sided CRC may have increased responsiveness to immunotherapy. Antibody-dependent cellular phagocytosis (ADCP) and antibody-dependent cellular cytotoxicity (ADCC) induced by M2-like macrophages were more pronounced in left-sided CRC and correlated with a good prognosis in CRC.

Transcriptional profiles in the chicken ductus arteriosus during hatching

Project description:The ductus arteriosus constricts after birth or hatching and eventually closes to terminate embryonic circulation. Chicken embryos have two long ductus arteriosus. Then the pulmonary artery-sided and descending aorta-sided ductus arteriosus have distinct functional characteristics, such as oxygen responsiveness. We used microarrays to elucidate the difference between the pulmonary artery-sided and descending aorta-sided ductus arteriosus in their transcriptional profiles.

Gene expression analysis of different passages and subclones of the Huh7 cell line

Project description:Hepatitis C Virus (HCV) has a extremely narrow host cell tropism and robustly infects only very few cell lines, most importantly the human hepatoma cell line Huh7. This cell line was isolated from a 57-year old Japanese male with fulminant hepatitis. Different subclones and passages of the Huh7 cell line show up to 1000-fold differences in HCV replication efficiency (permissiveness). In this experiment, we sought to identify factors responsible for these differences by correlating gene expression from eight different uninfected Huh7 variants with their respective HCV permissiveness. HCV replication efficiency was determined using electroporation of a subgenomic luciferase reporter replicon (genotype 1b, "con1/ET") and measuring luciferase activity at 48h post transfection normalized to the input value at 4h p.t.. "Relative permissiveness" of cell lines corresponds to their replication efficiency, normalized to the efficiency in the lowest permissive cells (Huh7 p13 and p28).

The Efficacy and Safety of Fruquintinib Plus Chemotherapy as Second-line Treatment in Metastatic Colorectal Cancer

Project description:This is a prospective, multi-center, randomized study evaluating the efficacy and safety of fruquintinib combined with chemotherapy vs bevacizumab combined with chemotherapy as second-line treatment in patients with metastatic colorectal cancer. Patients will receive fruquintinib+ FOLFIRI or bevacizumab+FOLFIRI as the second-line treatment. After receiving 4-6 months of second-line treatment, patients who achieve disease control will receive fruquintinib + capecitabine or bevacizumab+ capecitabine as maintenance treatment. All patients will be treated until progressive disease, death from any cause, unacceptable toxicity or informed consent withdrawal.
