Red blood cells were removed from samples using red blood cell lysis buffer (BioLegend). For the subcutaneous xenograft model in Fig. 8a, H1975 or HCC827 cells (1 × 107) with 50% Matrigel were injected subcutaneously into the mice. When the xenografts reached approximately 100 mm3,...
To test the role of PHD2 in IL-9 induction, we used Dox-inducible Phd2kd mice47 in which Phd2 gene encoding for prolyl hydroxylases 2 (PHD2) was knocked down upon Dox treatment. Naïve CD4+ T cells isolated from WT and Phd2kd mice were differentiated under Th9 polarizing conditions...

Red blood cells and mouse cells were eliminated using the ACK lysing buffer (Gibco A1049201) and Mouse cell depletion kit (Miltenyi Biotec 130-104-694), respectively. The tumor cells were resuspended in RPMI and used for internalization assays. Quantification and statistical analysis Statistical ...
目前可能有机会克服以上突变的第三代EGFR/TKI。 (1) Alflutinib(AST2818) (已在中国获得批准) Alflutinib (AST2818)是第三代EGFR 抑制剂,可将 EGFR 与敏感突变和EGFR 与 T790M- 介导的获得性耐药性突变相提并论。临床前研究表明,10和30 mg/kg Alflutinib组和10 mg/kg奥西替尼组对肿瘤生长的平均抑制分别...
5.2. Abdominal glucose tolerance test After an overnight fast, the rats were given an intraperitoneal injection of a 20 % glucose solution at a dose of 2 g per kilogram of body weight. To assess changes in blood glucose levels, venous blood samples were collected at intervals of 0, 30, ...
Importantly, enrichment of these distinct “rare” mutant-alleles by anti-EGFR therapy were also observed in the dataset with the Guardant360® ctDNA test both prior and post anti-EGFR treatment. In the 38 out of 131 mCRC patients with acquired alterations inKRAS, NRAS, BRAF, MAP2K1, EGF...
Ten days after drug treatment, the cells were harvested, and gDNA was extracted using the Blood and Cell Culture DNA Maxi kit (69506, Qiagen) according to the manufacturer’s protocols. The kinome CRISPR library prepared from the genomic DNA was subjected to HiSeq analysis. The CRISPR ...
Similarly, expression analyses of the CRC tumors identified increased IRS2 levels as a significant predictor of cetuximab sensitivity (p<0.001, Student's t-test) (36). Two additional tumorgrafts with IRS2 alterations (CRC508 and CRC106) that were not responsive to cetuximab harbored a MET ...
