Anticancer Res . 2016 Apr; 36(4):1563-70. PMID: 27069132
A retrospective observational cohort study has shown that exposure to alpha-1 adrenergic receptor (AR) blocker reduces the risk of bladder cancer (BCa). We investigated the antitumor activity of alpha-1 blockers,...

Tsuchiya A, Nagaya H, Kanno T, Nishizaki T
J Pharmacol Sci . 2014 Nov; 126(4):337-43. PMID: 25391857
The present study investigated cis-unsaturated free fatty acid (FFA)-regulated glucose uptake. In the cell-free assay of protein tyrosine phosphatase 1B (PTP1B), cis-unsaturated FFAs such as linoleic, linolenic, and oleic acid...

Mikami K, Nagaya H, Gotoh A, Kanno T, Tsuchiya A, Nakano T, et al.
Pharmacology . 2014 Oct; 94(3-4):163-9. PMID: 25301502
Naftopidil, an α1-adrenoceptor blocker, induced apoptosis of human malignant pleural mesothelioma NCI-H2052 cells. Naftopidil upregulated the expression of tumor necrosis factor-α (TNF-α) mRNA in these cells. Naftopidil, alternatively, increased FasL...

Kaku Y, Nagaya H, Tsuchiya A, Kanno T, Gotoh A, Tanaka A, et al.
Cancer Sci . 2014 Apr; 105(7):883-9. PMID: 24754309
The newly synthesized naftopidil analogue HUHS1015 reduced cell viability in malignant pleural mesothelioma cell lines MSTO-211H, NCI-H28, NCI-H2052, and NCI-H2452, with the potential greater than that for the anticancer drugs...

Tsuchiya A, Kanno T, Nagaya H, Shimizu T, Tanaka A, Nishizaki T
Cell Physiol Biochem . 2014 Apr; 33(4):1097-105. PMID: 24732916
Background/aims: The present study investigated the signaling pathway underlying Rac1 activation induced by the linoleic acid derivative 8-[2-(2-pentyl-cyclopropylmethyl)-cyclopropyl]-octanoic acid (DCP-LA). Methods: Activity of protein tyrosine phosphatase 1B (PTP1B) was assayed...

Tamura T, Arai S, Nagaya H, Mizuguchi J, Wada I
PLoS One . 2013 Sep; 8(9):e74580. PMID: 24040290
The endoplasmic reticulum (ER) plays essential roles in protein folding and assembly of secretory proteins. ER-resident molecular chaperones and related enzymes assist in protein maturation by co-operated interactions and modifications....

Cell Physiol Biochem . 2013 Jul; 31(6):905-13. PMID: 23817184
Background/aims: Our earlier studies suggested crosstalk between IRS/PI3 kinase/PDK1/Akt/Rac1/ROCK and (Shc2/Grb2/SOS)/Ras/Raf/MEK/ERK pathways downstream PDGF-ββ receptor responsible for chemotaxis and proliferation of malignant mesothelioma cells. The present study was conducted to...
