The paclitaxel/cisplatin combination therapy commonly is used as the first-line treatment for advanced ovarian cancer patients. Midkine (MK), known as a novel tumor biomarker, has been elevated in the serum of patients with epithelial ovarian cancer (EOC). In this study, we aimed to detect the expression of MK in EOC tissues and evaluate clinical value of MK in diagnosis and therapy of EOC. We ...

PURPOSE We tested the hypothesis that allosteric Akt inhibitor MK-2206 inhibits tumor growth, and that PTEN/PIK3CA mutations confer MK-2206 sensitivity. EXPERIMENTAL DESIGN MK-2206 effects on cell signaling were assessed in vitro and in vivo. Its antitumor efficacy was assessed in vitro in a panel of cancer cell lines with differing PIK3CA and PTEN status. Its in vivo efficacy was tested as a...

Midkine (MK) is a cytokine that modulates amphetamine-induced striatal astrogliosis, suggesting a possible role of MK in neuroinflammation induced by amphetamine. To test this hypothesis, we studied astrogliosis and microglial response induced by amphetamine (10 mg/kg i.p. four times, every 2 h) in different brain areas of MK-/- mice and wild type (WT) mice. We found that amphetamine-induced mi...

Monosomal karyotype (MK), defined as 2 or more monosomies, or a single monosomy in the presence of structural abnormalities, has recently been reported as identifying a distinct subset of acute myeloid leukemia (AML) patients with an extremely poor prognosis. In an effort to confirm this observation, we analyzed the prognostic impact of MK in 1344 AML patients between the ages of 16 and 88 year...

Midkine (MK) is a unique growth and differentiation factor that modulates the proliferation and migration of various cells; however, little is known regarding its relationship to intestinal diseases. The aim of this study was to investigate MK expression and its role in dextran sulfate sodium (DSS)-induced colitis in rats. The expressions of MK, receptor-like protein-tyrosine phosphatase (RPTP)...

The cytokine midkine (MK) promotes tumor growth mainly by inducing angiogenesis. Here, we identified the source of MK in the vascular system under hypoxic conditions and demonstrated the relevance of MK during ischemia of normal tissue. Hypoxia increased MK protein expression in human polymorphonuclear neutrophils (PMN), monocytes, and human umbilical vein endothelial cells (HUVEC) compared wit...

Monosomal karyotype (MK), defined as > 2 autosomal monosomies or a single monosomy in the presence of other structural abnormalities, was confirmed by several studies to convey an extremely poor prognosis in patients with acute myeloid leukemia (AML) with a 4-year overall survival after diagnosis of < 4%. A recent investigation by the Southwest Oncology Group found that the only MK patients ali...

Interim results of the C-WORTHY trial of the nonstructural (NS) 3/4A protease inhibitor MK-5172 and the NS5A replication complex inhibitor MK-8742 suggest that the combination exerts robust virologic suppression in treatment-naive patients with genotype (GT) 1 hepatitis C virus (HCV) infection. Interim results of C-WORTHY, a phase 2b trial, were reported by Eric Lawitz, MD, of the University of...

BACKGROUND Midkine (MK) is a heparin-binding growth factor involved in diverse biological phenomena, eg, neural survival, carcinogenesis, and tissue repair. MK could have a protective action against ischemia/reperfusion (I/R) injury in the heart, because MK was shown to have cytoprotective activity in cultured neurons and tumor cells. We investigated this hypothesis in mice with and without gen...
