The Role Of Lipocalin 2 In Early Stage Colon Cancer Metastasis To The Liver, Fides Elamparo
The Role Of Lipocalin 2 In Early Stage Colon Cancer Metastasis To The Liver, Fides Elamparo
Senior Theses
Metastasis, frequently from the colon to the liver, is the major cause of death with colorectal cancer, reducing the five-year survival to less than 6%. Metastasis occurs due to productive collaborations between tumor cells and host-derived cells in the tumor microenvironment, where a pre-metastatic niche is created to prime for cancer cell invasion into the target organ. In a highly metastatic colorectal cancer cell line implanted into the cecum of Balb/c mice, microarray analysis showed lipocalin 2 (Lcn2) is one of the most highly expressed proteins in the liver of tumor-bearing mice prior to metastasis.

Theses and Dissertations
Human epidermal growth factor receptor 2 (HER2) is overexpressed in approximately 30% of breast cancer patients with poor prognosis. In addition, microRNAs are small non-coding RNA that have been linked to many cancers. Here we investigate which miRNAs are differentially regulated by HER2 overexpression. Using quantitative reverse-transcription prolymerase chain reaction (QRT-PCR) and matching it with the clinical data acquired from Dvinge, we find five candidate miRNAs. When comparing the miRNAs’ effect on patient survival, only three miRNAs stand as good predictors of patient survival outcome. These miRNAs are miR-146a-5p, miR-181d, and miR-195-5p. When miR-146a-5p is up-regulated, which is the case …
