Time-Dependent Proteome Study: Human-in-mouse xenograft breast cancer tumor samples (0, 5, 30, 60 min)


ABSTRACT: The objective of the Time-Dependent Proteome Study was to evaluate changes in the proteome and phosphoproteome when there is a delay in freezing tissues following sample (tumor) excision. The biospecimens used are from human-in-mouse breast cancer tumor samples.

Protein abundance and phosphorylation convey important information about pathway activity and molecular pathophysiology in diseases including cancer, providing biological insight, informing drug and diagnostic development, and guiding therapeutic intervention. Analyzed tissues are usually collected without tight regulation or documentation of ischemic time. To evaluate the impact of ischemia, we collected human ovarian tumor and breast cancer xenograft tissue without vascular interruption and pe  ...[more]
