1 A whole genome microarray analysis, using a BT474 cell line, reveals genes significantly modulated (positively or negatively) after LMTK3 silencing, including some that are known to be implicated in Tam resistance, notably c-MYC, HSPB8 and SIAH2. Tamoxifen lemur tyrosine kinase 3 Homo sapiens
2 We show that LMTK3 is able to increase the levels of HSPB8 at a transcriptional and translational level thereby protecting MCF7 cells from Tam-induced cell death, by reducing autophagy. Tamoxifen lemur tyrosine kinase 3 Homo sapiens
3 Finally, high LMTK3 levels at baseline in tumors are predictive for endocrine resistance; therapy does not lead to alteration in levels, whereas in patient"s plasma samples, acquired LMTK3 gene amplification (copy number variation) was associated with relapse while receiving Tam. Tamoxifen lemur tyrosine kinase 3 Homo sapiens
