Genetic alterations and oxidative metabolism in sporadic colorectal tumors from a Spanish community

1997

Deletions of loci on chromosomes 5q, 17p, 18q, and 22q, together with the incidence of p53 mutations and amplification of the double minute-2 gene were investigated in the sporadic colorectal tumors of 44 patients from a Spanish community. Chromosome deletions were analyzed by means of loss of heterozygosity analysis using a restriction fragment length polymorphism assay. Allelic losses were also detected by polymerase chain reaction (PCR)-single-stranded conformation polymorphism (SSCP) analysis of a polymorphic site in intron 2 of the p53 gene. The percentages of genetic deletions on the screened chromosomes were 39.3% (5q), 58.3% (17p), 40.9% (18q), and 40% (22q). Mutations in p53 exons …

Immunosuppressive profiles in liquid biopsy at diagnosis predict response to neoadjuvant chemotherapy in triple-negative breast cancer.

2020

Background: Triple-negative breast cancer (TNBC) is characterised by high pathological complete response to neoadjuvant chemotherapy (NAC). However, refractory and poor NAC responders still face very poor outcome, emphasising the urgent need for tools that facilitate identification of these patients, so that surgery or alternatives to NAC are considered early in the treatment protocol. Materials and methods: We combined metabolomics, exosome circulating miRNAs and flow cytometry experimental approaches in TNBC patients at diagnosis with immunohistochemistry in needle biopsy tumours to generate NAC-response predictive models. We also co-cultured and studied crosstalk between isolated patient…
