This invention relates to pharmaceutical compositions comprising plant deoxyribonucleoside kinase enzymes (dNK) capable of phosphorylating nucleoside analogs and to medical use of said dNKs. More specifically the invention relates to the medical use of deoxyribonucleoside kinase enzymes derived from (
Arabidopsis thaliana
), from loblolly pine (
Pinus taeda
), from tomato (
Lycopersicum esculentum
), from maize (
Zea mays
) or from rice (
Oryza sativa
). The invention also relates to methods of sensitising cells to prodrugs, and to methods of inhibiting pathogenic agents in warm-blooded animals using said plant dNKs.
In another aspect the invention relates to plant derived deoxyribonucleoside kinase enzymes provided in isolated form from loblolly pine (
Pinus taeda
), from tomato (
Lycopersicum esculentum
), from maize (
Zea mays
) or from rice (
Oryza sativa
). In further aspects the invention provides polynucleotides encoding the plant dNKs, vector constructs comprising the polynucleotide, packaging cell lines capable of producing said vector, and genetically modified isolated host cells transduced/transfected/-transformed with the vector.
本发明涉及包含能使核苷类似物磷酸化的植物脱氧核苷激酶(dNK)的药物组合物,以及所述 dNK 的医学用途。更具体地说,本发明涉及源自(
拟南芥
)、龙柏(
太田松
)、番茄(
番茄
)、玉米(Zea mays
玉米
)或水稻(Oryza sativa
Oryza sativa
).本发明还涉及使细胞对原药敏感的方法,以及使用所述植物 dNK 抑制温血动物中病原体的方法。
在另一个方面,本发明涉及植物衍生的脱氧核苷激酶,它以分离形式提供自小叶松(
太田松
)、番茄(
Lycopersicum esculentum
)、玉米(
玉米
)或水稻(Oryza sativa
Oryza sativa
).在进一步的方面,本发明提供了编码植物 dNKs 的多核苷酸、包含多核苷酸的载体构建体、能够产生所述载体的包装细胞系,以及用载体转导/转染/转化的转基因分离宿主细胞。
