Cloning and prokaryotic expression of human Cyclin D1 gene / 中国医师杂志

ABSTRACT

Objective To obtain the Cyclin D1 through cloning and prokaryotic expression of Cyclin D 1 gene.Methods The total RNA was extracted from liver cancer tissue .The Cyclin D1 cDNA was obtained by reverse transcriptase polymerase chain reaction (RT-PCR).The Cyclin D1 cDNA was sequenced, and sub-cloned to the PET32a+.The prokaryotic expressed was used to obtain the Cyclin D1.Results The 483 bp Cyclin D1 cDNA was obtained.The sequence of Cyclin D1 was corrected.The 36 KD CyclinD1 was obtained by prokaryotic expression .Conclusions The Cyclin D1 cDNA was obtained.Cyclin D1 was expressed in BL21.
