We tested the effects of alisertib or AURKA overexpression or knockdown in 10 upper gastrointestinal or colon cancer cell lines with KRAS mutations or amplifications using the CellTiter-Glo luminescence and clonogenic cell survival assays.
The present study is aimed to evaluate the effects of Lactobacillus acidophilus and Bifidobacterium bifidum probiotics on the expression of miRNAs 135b, 26b, 18a, and 155 and their target genes, including APC, PTEN, KRAS, and PU.1 in mouse azoxymethane (AOM)-induced colon cancer.
The lack of mutant KRAS-induced effector activation observed in SW48 cells appears to be representative of a broad panel of colon cancer cell lines harboring mutant KRAS.
In addition, we identified a KRAS codon 146 mutation (A146V), which is associated with resistance to anti-EGFR, in a cetuximab-resistant colon cancer patient with wild-type KRAS exons 2 and 12, and EGFR amplification.He received bevacizumab therapy.
The kinetics of ctDNA derived from each cancer type were monitored targeting BRAF V600R (melanoma) and KRASG13D (colon cancer), specifically reflected the status of the patient's tumours.
Here we investigated whether combination of 5-FU and a MEK inhibitor had treatment sequence-dependent synergistic effects in KRAS or BRAF mutant colon cancer models.
Our study provides new insights into the mechanisms of resistance to KRAS ablation, and suggests novel strategies for the treatment of KRAS-mutant colon cancers.
Quest for metabolic inhibitors with anti-tumour activity may constitute a novel and hopeful approach in order to handle KRAS dependent chemoresistance in colon cancer.
Immunohistochemistry with Anti-BRAF V600E (VE1) Mouse Monoclonal Antibody is a Sensitive Method for Detection of the BRAF V600E Mutation in Colon Cancer: Evaluation of 120 Cases with and without KRAS Mutation and Literature Review.
We examined the anti-proliferative effect of miR-143#12 and the mechanism in human colon cancer DLD-1 cell (G13D) and other cell types harboring K-Ras mutations.
Targeting bioenergetic metabolism with mitochondria-targeted drugs to stimulate mitophagy provides an attractive approach for therapeutic intervention in KRAS WT and overactive mutant-expressing colon cancer.
Furthermore, EGF‑ETA was just as potent in HCT116 (KRASG13D) and SW480 (KRASG12V) colon cancer cell lines harbouring KRAS hyperactivating mutations when compared to KRAS wild‑type HT29 colon cancer cells.
Collectively, Src can play a key role in apoptosis induced by the novel EGFR inhibitor MHYs, suggesting that activation of Src might prove effective in treating EGFR/wild-type KRAScolon cancer.
Together, these results identify that the HSF1-BAG3-Mcl-1 signal axis is critical for protection of mutant KRAScolon cancer cells from AUY922-induced apoptosis, with potential implications for targeting HSF1/BAG3/Mcl-1 to improve the efficacy of AUY922 in the treatment of colon cancer.
Methods The data of patients with lung metastases from colon cancer who underwent SABR were retrospectively evaluated according to the following inclusion criteria: number of metastases ≤3; lung oligometastases from colon cancer in patients who underwent SABR; patients receiving previous chemotherapy alone or in combination with bevacizumab; Karnofsky performance status >80; life expectancy >6 months; at least 6 months' follow-up after SABR; presence of KRAS mutation.
In this study, we assessed and compared the mutational status of KRAS, NRAS, and PIK3CA in PDCs and corresponding main tumor tissue of 25 CCs with KRAS mutations.
