FEBS Open Bio, 2019 Receptor‐type protein tyrosine phosphatase κ (PTPRK) is considered to be a candidate tumor suppressor. PTPRK dephosphorylates CD133, which is a stem cell marker; phosphorylated CD133 accelerates xenograft tumor growth of colon cancer cells through the ...

Phosphorylation events surrounding the DNA damage response in "Saccharomyces cerevisiae" [PDF]
, 2007 Protein phosphorylation mediated by checkpoint kinases is crucial for the cellular response to DNA damage. The sensor kinases Mec1 and Tel1 initiate the checkpoint signaling cascade by directly activating the checkpoint effector kinase Rad53.

Regulation of protein kinase B (PKB/Akt) by DNA-dependent protein kinase (DNA-PK) under physiological conditions [PDF]
, 2010 The serine/threonine protein kinase B (PKB/Akt) is a downstream effector of phosphatidylinositol 3-kinase (PI3K) and a major regulator of a variety of cellular processes, including metabolism, transcription, survival, proliferation, and growth.

DNA Damage and DNA Damage Response in Chronic Myeloid Leukemia [PDF]
International Journal of Molecular Sciences, 2020 DNA damage and alterations in the DNA damage response (DDR) are critical sources of genetic instability that might be involved in BCR-ABL1 kinase-mediated blastic transformation of chronic myeloid leukemia (CML). Here, increased DNA damage is detected by γH2AX foci analysis in peripheral blood mononuclear cells (PBMCs) of de novo untreated chronic ...

DNA damage responses in the context of the cell division cycle [PDF]
, 2010 During my PhD, I have investigated aspects of the DNA damage response (DDR) in the context of three different cellular scenarios: DNA damage signalling in response to double-strand breaks during mitosis, coordination of DNA replication with DNA damage ...

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1999 Mycotoxins are toxic fungal metabolites which are structurally diverse, common contaminants of the ingredients of animal feed and human food. To date, mycotoxins with carcinogenic potency in experimental animal models include aflatoxins, sterigmatocystin, ochratoxin, fumonisins, zearalenone, and some Penicillium toxins.
