Project description:we demonstrated that N-Myc Downstream Regulated 1 (NDRG1) interacts with and restrains Neuregulin 2 (NRG2) to down-regulate the EGFR. This inhibition prevents excessive autophagy protection, thereby reducing EGFR TKI drug resistance in lung cancer cell lines and xenograft mouse models. Activation of NDRG1 using compounds like Chinese herb extract Flos Magnoliae and its active monomer (magnolin) restored sensitivity in resistant cell lines to EGFR TKIs and delayed resistance in lung cancer xenograft mice. These findings highlight a mechanism for resistance to a molecularly targeted therapy and provide a potential therapeutic target for overcoming resistance to EGFR TKIs, including the second-generation inhibitor afatinib
Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

Project description:One ONT-ULK sequencing run from the kidney of a single male CDMR (Bathyergus suillus) sample used to make the mBatSui1.1.primary genome assembly as an evolutionary comparator to our telomere-to-telomere naked mole-rat genome assembly. Specifically, we assembled a CDMR from a wild-derived sample in South African cape and sequenced in Toronto, Canada, using PacBio HiFi (89 Gb, read N50 = 18 Kb) and ONT-ULK (55 Gb, read N50 = 43 Kb) reads (contig N50 = 33 Mb, Compleasm S = 99%, QV = 71.0). This accession stores the ONT-ULK data for this assembly.

Project description:Two PacBio Hifi sequencing runs from the kidney of a single male NMR sample used to make the mHetGla4.1.primary genome assembly. Specifically, we assembled a second NMR genome from an unrelated male of a separate captive colony in Toronto, Canada, using PacBio HiFi (155.8 Gb, read N50 = 11.45 Kb) and ONT-LSK (299.6 Gb, read N50 = 10.1 Kb) reads (contig N50 = 75.7 Mb, Compleasm S = 98%). This accession stores the Pacbio Hifi data for this independent assembly.
