Spatial transcriptomics of triple negative breast cancer

Project description:Triple negative breast cancer (TNBC) is an aggressive and clinically challenging subtype of breast cancer. TNBC disporportionately affects African-American (AA) women, but the biological basis of this disparity is not understood. To gain a better understanding of TNBC, particularly in AA patients, we applied spatial transcriptomics to thoroughly characterize gene expression and tissue architecture in TNBC. Our cohort consisted of 22 patients, 15 of whom were AA, and 7 who were Caucasian. We obtained 2 sections from each patient's tumor (except for patient 19) for a total of 43 samples.

GeoMx digital spatial profiling on biopsies of triple negative breast cancer patients

Project description:In this study, we analyzed the differential spatial transcriptome of Triple-Negative Breast Cancer (TNBC) patients who responded in an opposite manner to neoadjuvant chemotherapy (NACT): we compared responders displaying pathological complete response (pCR) with no-responders who showed disease progression during therapy. Diagnostic TruCut biopsies were analyzed using the GeoMx Cancer Transcriptome Atlas (Nanostring).

Triple Negative Breast tumors: SPARC Positive Tumors vs SPARC Negative Tumors

Project description:The aim of this study was evaluate the transcriptome changes in the comparison between triple negative tumors with increased SPARC expression and triple negative tumors with decreased SPARC expression according to Nagai et al., 2011 (Breast Cancer Res Treat (2011) 126:1–14) The results generated could be of particular interest to better define the prognostic impact of SPARC expression in triple negative breast tumors

7-Hydroxystaurosporine and Irinotecan Hydrochloride in Treating Patients With Metastatic or Unresectable Solid Tumors or Triple Negative Breast Cancer (Currently Accruing Only Triple-negative Breast Cancer Patients Since 6/8/2007)

Project description:This phase I trial is studying the side effects and best dose of giving 7-hydroxystaurosporine together with irinotecan hydrochloride in treating patients with metastatic or unresectable solid tumors, including triple-negative breast cancer (currently enrolling only patients with triple-negative breast cancer since 6/8/2007). Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving 7-hydroxystaurosporine together with irinotecan hydrochloride may help kill more cancer cells by making tumor cells more sensitive to the drug.

Differential analysis of nucleolar proteomics in triple negative breast cancer

Project description:Breast cancer is one of the most common cancers in women. Of the different subtypes of breast cancer, the triple negative breast cancer subtype of breast cancer is the most aggressive. A proteomic screen of nucleolar content across breast cancer subtypes found that triple negative breast cancer cell lines have a distinct nucleolar proteome signature in comparison to non-TNBC breast cancer cell lines.
