Transcriptomics changes in liver metastatic biopsies of colorectal carcinoma between pre-treated and acquired resistance to Cetuximab [mRNA]

ABSTRACT: Two patients who were newly diagnosed and pathologically confirmed metastatic colorectal cancer were screened for eligibility between August 2011 and December 2013 in Affiliated Hospital, Academy of Military Medical Sciences. They were treated with Cetuximab in combination with FOLFOX regimen and obtained continuous partial responses in more than six months. CT scans of liver lesions were performed every two to eight weeks. The four biopsies were evaluated by two pathologists and were confirmed that the tumor purities were greater than 50%. Each biopsy was subjected to high-throughput RNA and small RNA sequencing to obtain expression profiles of genes and miRNAs.

Exploring MicroRNA Patterns as Biomarkers of FOLFOX Chemotherapy-Induced Peripheral Neuropathy in Patients with Colorectal Cancer

Project description:This study aimed to identify potential miRNA-based biomarkers that can predict FOLFOX-CIPN symptoms. High throughput microRNA sequencing was performed on the RNA circulating in the plasma of eight patients with CRC who underwent FOLFOX chemotherapy. miRNA expression profiles were evaluated according to two groups: those who underwent ≤three cycles and those who underwent ≥six cycles of FOLFOX chemotherapy.

Seasonal bud dormancy progression

Project description:This study investigated changes in the transcriptome of outdoor grown leafy spurge crown buds as they progress from paradormancy in August and September into endo dormancy in October through to ecodormancy in November and December. Keywords: Dormancy leafy spurge adventitious-buds A series of balanced dyeswap rolling circle hybiridizations were used with each year representing s seperate circle and with direction of the circles reversing on alternate years. Note, the Aug-Sep 04 hybridization failed and is missing from the dataset

Paired subcloned human large cell lung carcinoma cell lines: low-metastatic 95C vs high-metastatic 95D

Project description:The paired low-metastatic 95C and high-metastatic 95D cell lines were subcloned from a low differentiated human large cell lung carcinomacell line PLA-801. The cells were well authenticated and published by several research groups. The cells were kindly provided by Professor Ying-Lin Lu, Department of Pathobiology, Institute of Basic Medical Sciences, Academy of Military Medical Sciences, Beijing, China on Dec. 5，2009. As described The 95C and 95D cells were cultured in RPMI 1640 (Invitrogen, USA) with 100 units/mL penicillin, 100 μg/mL streptomycin and 10% calf bovine serum, and grown at 37° C in atmosphere with 5% CO2. miRNAs differential expression between 95C and 95D was measured using a miR human_01_H10.1_080277 miRNA array (LC Sciences Houston, USA).

Single-Cell Analysis Reveals Cellular Reprogramming in Advanced Colon Cancer Following FOLFOX-Bevacizumab Treatment

Project description:The combination of FOLFOX and bevacizumab (FOLFOX-Bev) is a promising treatment for advanced colorectal cancer (CRC). To gain insights into the cellular changes associated with FOLFOX-Bev treatment, we conducted single-cell transcriptomic analysis of CRC samples derived from a patient before and after treatment. Our results show that cancer cells with high proliferative, metastatic, and pro-angiogenic properties respond better to FOLFOX-Bev treatment. Moreover, FOLFOX-Bev enhances CD8+ T cell cytotoxicity, thereby boosting the anti-tumor immune response. Conversely, FOLFOX-Bev impairs the functionality of tumor-associated macrophages, plasma cells, and cancer-associated fibroblasts, leading to a decrease in VEGFB-mediated angiogenesis. Furthermore, FOLFOX-Bev treatment reset intercellular communication, which could potentially affect the function of non-cancer cells. Our findings provide valuable insights into the molecular mechanisms underlying the response of advanced CRC to FOLFOX-Bev treatment and highlight potential targets for improving the efficacy of this treatment strategy.

The cells were well authenticated and published by several research groups. The cells were kindly provided by Professor Ying-Lin Lu, Department of Pathobiology, Institute of Basic Medical Sciences, Academy of Military Medical Sciences, Beijing, China on Dec. 5M-oM-<M-^L2009. As described The 95C and 95D cells were cultured in RPMI 1640 (Invitrogen, USA) with 100 units/mL penicillin, 100 M-NM-<g/mL streptomycin and 10% calf bovine serum, and grown at 37M-BM-0 C in atmosphere with 5% CO2. miRNAs differential expression between 95C and 95D was measured using a miR human_01_H10.1_080277 miRNA array (LC Sciences Houston, USA). Paired subcloned human large cell lung carcinomacell line PLA-801 of low-metastatic 95C and high-metastatic 95D cell lines. Biological replicates:1. Five replicate per array.
