The liver kinase B1 (LKB1)/5'-adenosine monophosphate-activated protein kinase pathway has been reported to facilitate glioma cell growth by improving growth conditions. To investigate the clinical significance of LKB1 in human gliomas western blot analysis and quantitative polymerase chain reaction experiments were performed. The present study demonstrated that LKB1 expression was markedly dec...
The human LKB1 tumor suppressor has been implicated as an important regulator of many cellular processes and signaling pathways, indicating that it could be a good candidate for anticancer drugs. The failure of its obtain high-level expression has been a major obstacle to study its protein structure and function in vitro. Here, we describe the high-level expression of human LKB1 in Escherichia ...
The serine/threonine kinase LKB1 has a conserved role in Drosophila and nematodes to co-ordinate cell metabolism. During T lymphocyte development in the thymus, progenitors need to synchronize increased metabolism with the onset of proliferation and differentiation to ensure that they can meet the energy requirements for development. The present study explores the role of LKB1 in this process a...
Loss of LKB1 activity is prevalent in KRAS mutant lung adenocarcinoma and promotes aggressive and treatment-resistant tumors. Previous studies have shown that LKB1 is a negative regulator of the focal adhesion kinase (FAK), but in vivo studies testing the efficacy of FAK inhibition in LKB1 mutant cancers are lacking. Here, we took a pharmacologic approach to show that FAK inhibition is an effec...
The discovery of somatic mutations in cancer-related genes has been applied to understand the genetic basis of cancer. Here we report somatic mutations of two tumor suppressor genes: LKB1 (exons 1, 4, and 8) and TP16 (CDKN2A) (exons 1 and 2); and two oncogenes: epidermal growth factor receptor EGFR (exons 18-21) and KRAS (exon 2) in 97 lung adenocarcinoma tissues in a cohort from the Kujukuri c...
LKB1 acts as a master upstream protein kinase regulating a number of kinases involved in diverse cellular functions. Recent studies have suggested a role for LKB1 in male fertility. Male mice with reduced total LKB1 expression, including the complete absence of the major splice variant in testis (LKB1(S)), are completely infertile. We sought to further characterise these mice and determine the ...
