Breast Cancer Sheet Cheat Cheat Sheet (DRAFT) by

breast cancer

This is a draft cheat sheet. It is a work in progress and is not finished yet.

One Minute Pitch

Breast cancer is a complex disease with great clinical and molecular hetero­geneity that requires accurate assessment of known breast cancer biomar­kers, such as HER2, estrogen receptor (ER), and proges­terone receptor (PgR), as well as the discovery of emerging potential targets, for the precise treatment of breast tumors. The RNAscope® in situ hybrid­ization assay offers a very reliable and robust method for the detection and validation of breast cancer­-re­lated markers within the tissue enviro­nment and can be performed on routinely available FFPE samples.

Examples of RNAscope in Breast Cancer Research

Resolution of equivocal and hetero­geneous cases of HER2 expres­sion: Standard HER2 testing methods are often hampered by equivocal testing and intrat­umoral hetero­gen­eity. Wang et al. developed a fully automated, quanti­tative ISH assay using the RNAscope® technology to quantify single­-cell HER2 mRNA levels. http:/­/bi­t.l­y/2­qGSIWG
Patien­t-s­tra­tif­ication for treatment regimens: Vassil­ako­poulou et al. used the RNAscope® assay to assess HER2 mRNA as a predictor of benefit from trastu­zum­ab-­based chemot­herapy and to correlate it to HER2 protein and gene levels. http:/­/bi­t.l­y/2­rtsyHZ
Validation of transc­riptome data and sub-ce­llular locali­zation of lncRNA in breast cancer: In their study Lin et al. selected lncRNA LINK-A as it shows frequently elevated expression in TNBC patients. RNAscope® ISH confirmed the array results, showing that expression of LINK-A was signif­icantly increased in TNBC tissues. http:/­/bi­t.l­y/2­qMojGT
Precli­nical drug efficacy for breast cancer treatment: FGFR2 gene amplif­ication is found in 4% of triple­-ne­gative breast cancers (TNBC). In their study, Sommer et al. demons­trate the precli­nical efficacy of BAY118­7982, a novel FGFR2-­ant­ibody drug conjugate (ADC). http:/­/bi­t.l­y/2­rtlStB
Assessment of HOTAIR as a prognostic breast cancer biomarker for breast cancer: High expression of the large intergenic non-coding RNA (lincRNA) HOTAIR has been shown to be a signif­icant predictor of poor prognosis and metastasis in breast carcin­omas. Gökmen­-Polar et al. showed that the prognostic role of HOTAIR is restricted to ER-/lymph node+ tumors, where its expression could be used as a potential prognostic marker. http:/­/bi­t.l­y/2­rKKHxs
