Project description:The individualized treatment of tumors has always been an urgent problem in clinical practice. Organoids-on-a-chip can reflect the heterogeneity of tumors and is a good model for in vitro anticancer drug screening. In this study, surgical specimens of patients with advanced colorectal cancer will be collected for organoid culture and organoids-on-a- chip. Use organoids-on-a-chip to screen tumor chemotherapy drugs, compare the results of patients’ actual medication regimens, and study the guiding role of organoids in the formulation of precise tumor treatment plans. The investigators will compare the response of organoids to drugs in vitro with the patient’s response to actual chemotherapy and targeted drugs and explore the feasibility and accuracy of organoids-on-a-chip based drug screening for advanced colorectal cancer. The project will establish a screening platform for chemotherapeutic drugs and targeted drugs based on colorectal cancer organoids to quickly and accurately formulate personalized treatment plans for clinical patients.

Project description:Global analysis of H3K4 methylation defines MLL family member targets and points to a role for MLL1-mediated H3K4 methylation in the regulation of transcriptional initiation by RNA polymerase II A common landmark of activated genes is the presence of trimethylation on lysine 4 of histone H3 (H3K4) at promoter regions. The Set1/COMPASS was the founding member and the only H3K4 methylases in S. cerevisiae, however, in mammals at least six H3K4 methylases Set1A/B and MLL1-4 are found in COMPASS-like complexes capable of methylating H3K4. To gain further insight into the different roles and functional targets for the H3K4 methylases, we have undertaken a genome-wide analysis of H3K4 methylation pattern in wild-type Mll1+/+ and Mll1-/- mouse fibroblasts (MEFs). We found that Mll1 is required for the H3K4 trimethylation of less than 5% of promoters carrying this modification. Many of these genes, which include developmental regulators such as Hox genes show decreased levels of RNA polymerase II recruitment and expression concomitant with the loss of H3K4 methylation. Although Mll1 is only required for the methylation of a subset of Hox genes, Menin, a component of the Mll1 and Mll2 complexes, is required for the overwhelming majority of H3K4 methylation at Hox loci. However, the loss of MLL3/4 and/or the Set1 complexes have little to no effect on the Hox loci H3K4 methylation or expression levels in these MEFs. Together these data provide insight into redundancy and specialization of COMPASS-like complexes in mammals and provide evidence on a possible role for Mll1-mediated H3K4 methylation in the regulation of transcriptional initiation. Chromatin Immunoprecipitation was performed with antibodies for histone 3 lysine 4 trimethylation, histone 3, and PolII in Mll1+/+ and Mll1-/- mouse embryonic fibroblasts. DNA was hybridized to a custom Agilent tiling array (4x44k format) that covers three of the hox regions (A,B,D) and a collection of other genes.

Expression arrays were done with Mll1+/+ and Mll1-/- mouse embryonic fibroblasts. Four replicates were done (dyes were swapped). DNA was hybridized to Agilent Mouse Whole Genome Expression Arrays (4x44k).
