We were looking for new markers to help us better predict treatment benefit and\/or outcome with patient-specific or individualized precision.\u201d<\/p>\n<p style=\"text-align: justify; \">In their study, researchers drew upon \u201calternative splicing,\u201d a phenomenon in which cells cut, or splice, particular genome areas in different ways to make new arrangements. With these different arrangements, the cell can produce different proteins from original genome, depending on how it\u2019s differentially arranged. While this occurs in normal cells, emerging evidence show that cancer cells can take advantage of alternative splicing to help them grow or proliferate. Researchers used this concept to develop a method of sorting breast cancer cells according to the differences in certain proteins known as trans-factors that occurred in different breast cancer subtypes.<\/p>\n<p style=\"text-align: justify; \">\u201cAberrant alternative splicing is a major hallmark of cancer, where RNA cis-acting splicing regulatory elements, such as intronic splicing enhancers, interact with particular trans-acting proteins, or trans-factors, to coordinately elicit the control of alterative splicing,\u201d Chen said. \u201cWhat we found is that in different breast cancer subtypes, the composition of trans-factors is different.\u201d<\/p>\n<p style=\"text-align: justify; \">Read the <a class=\"external-link\" href=\"http:\/\/news.unchealthcare.org\/news\/2018\/march\/prognostic-tool-could-identify-high-risk-breast-cancer-patients\" target=\"_self\" title=\"UNC Vital Signs Chen News Prognostic tool could identify high-risk breast cancer patients\">full article at UNC Vital Signs<\/a><\/p>\n<p style=\"text-align: justify; \"><i>In addition to Chen, other authors include Li Wang, John A.
