A bottleneck in drug discovery is the identification of molecular targets a compound (mode action, MoA) and its off-target effects. Previous approaches to elucidate MoA include analysis chemical structures, transcriptional responses following treatment, text mining. Methods based on require least amount information can be quickly applied new compounds. Available methods are inefficient not able support network pharmacology. We developed an automatic robust approach that exploits similarity...

In metastatic colorectal cancer (CRC), actionable genetic lesions represent potential clinical opportunities. NTRK1, 2, and 3 gene rearrangements encode oncogenic fusions of the tropomyosin-receptor kinase (TRK) family receptor tyrosine kinases in different tumor types. The TPM3-NTRK1 rearrangement is a recurring event CRC that renders tumors sensitive to TRKA inhibitors preclinical models. We identified abnormal expression protein liver metastases patient refractory standard therapy....

Chordomas are rare bone tumors with no approved therapy. These express several activated tyrosine kinase receptors, which prompted attempts to treat patients inhibitors. Although clinical benefit was observed in phase II trials imatinib and sorafenib, sporadically also EGFR inhibitors, therapies evaluated date have shown modest activity. With the goal of identifying new drugs immediate therapeutic potential for chordoma patients, we collected clinically other advanced inhibitors MET, PDGFRβ,...

Poly(ADP-ribose) polymerase-2 (PARP2) belongs to the ADP-ribosyltransferase family of enzymes that catalyze addition ADP-ribose units acceptor proteins, thus affecting many diverse cellular processes. In particular, PARP2 shares with PARP1 and, as recently highlighted, PARP3 sole property being catalytically activated by DNA-strand breaks, implying key downstream functions in response DNA damage for both enzymes. However, evidence from several studies suggests unique additional processes,...

Abstract Background RNA-Seq is a well-established technology extensively used for transcriptome profiling, allowing the analysis of coding and non-coding RNA molecules. However, this produces vast amount data requiring sophisticated computational approaches their than other traditional technologies such as Real-Time PCR or microarrays, strongly discouraging non-expert users. For reason, dozens pipelines have been deployed data. Although interesting, these present several limitations usage...

Chordomas are rare, slowly growing tumors with high medical need, arising in the axial skeleton from notochord remnants. The transcription factor "brachyury" represents a distinctive molecular marker and key oncogenic driver of chordomas. Tyrosine kinase receptors also expressed, but so far inhibitors have not shown clear clinical efficacy chordoma patients. need for effective therapies is extremely high, paucity established cell lines has limited preclinical research.
