Abstract Text

Genetic alterations that lead to constitutive activation of kinases are frequently observed in cancer. In many cases, the growth and survival of tumor cells rely upon an activated kinase such that inhibition of its activity is an effective anticancer therapy. ROS1 is a receptor tyrosine kinase that has recently been shown to undergo genetic rearrangements in a variety of human cancers, including glioblastoma, non-small cell lung cancer (NSCLC), cholangiocarcinoma, ovarian cancer, gastric adenocarcinoma, colorectal cancer, inflammatory myofibroblastic tumor, angiosarcoma, and epithelioid hemangioendothelioma. These rearrangements create fusion proteins in which the kinase domain of ROS1 becomes constitutively active and drives cellular proliferation. Targeting ROS1 fusion proteins with the small-molecule inhibitor crizotinib is showing promise as an effective therapy in patients with NSCLC whose tumors are positive for these genetic abnormalities. This review discusses the recent preclinical and clinical findings on ROS1 gene fusions in cancer.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

ROS1	NCBI	MCF3\|ROS\|c-ros-1		ROS1, ROS proto-oncogene 1, receptor tyrosine kinase, is an orphan receptor tyrosine kinase that may activates multiple pathways involved in cell survival and transformation (PMID: 23719267, PMID: 32327173). ROS1 fusion proteins frequently lead to constitutive activation of Ros1 signaling and have been identified in glioblastoma, non-small cell lung cancer, cholangiocarcinoma, ovarian cancer, gastric adenocarcinoma, colorectal cancer, inflammatory myofibroblastic tumor, angiosarcoma, glioma, and epithelioid hemangioendothelioma (PMID: 23719267, PMID: 30262706, PMID: 30171048, PMID: 3004937), and ROS1 mutations are often associated with acquired resistance to inhibition (PMID: 31256210).
