Gemcitabine is an inhibitor of DNA synthesis [1].
DNA synthesis is a natural creation of deoxyribonucleic acid (DNA) molecules and plays an important role in cell growth.
Gemcitabine is an active chemotherapeutic agents that disrupt DNA replication. In tumor cells, gemcitabine activated checkpoint kinase 2 (Chk2) and ataxia-telangiectasia mutated kinase (ATM), which regulated apoptosis, DNA repair and cell-cycle arrest. Also, gemcitabine activated the Rad9-Hus1-Rad1 complex and the protein kinases ATM and ATR and checkpoint kinase 1 (Chk1), which blocked cell-cycle progression and influence DNA repair [1]. Gemcitabine is a DNA synthesis inhibitor with anti-tumor activity. In human osteosarcoma cell lines HOS and MG63, gemcitabine inhibited DNA synthesis and induced apoptosis [2].
In C3H mice inoculated with murine osteosarcoma cell line LM8, gemcitabine induced cell apoptotics and reduced the size of primary tumor. Also, it inhibited metastatic lesions in the lung [2]. In C57Bl/6 mice infected with LP-BM5 murine leukemia virus, gemcitabine significantly inhibited disease progression. Also, gemcitabine reduced spleen size, provirus levels and plasma IgM [3].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
HeLa cells, K562 cells, HOS and MG63 cell lines. |
|
Preparation method |
The solubility of this compound in DMSO﹥10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
100 nM gemcitabine for 3 h in HeLa cells for immunofluorescence, 500 nM gemcitabine for 6 h for SDS-PAGE |
|
Applications |
In Hela cells and K562 cells, gemcitabine activated both the ATR/Chk1 and ATM/Chk2 signaling pathways. (ATR: ataxia-telangiectasia mutated and Rad3-related kinase; Chk: checkpoint kinase; ATM: ataxia-telangiectasia mutated kinase). Gemcitabine is a DNA synthesis inhibitor with anti-tumor activity. In human osteosarcoma cell lines HOS and MG63, gemcitabine inhibited DNA synthesis and induced apoptosis. |
| Animal experiment [2]: | |
|
Animal models |
Female C57BL/6 mice infected with LP-BM5 MuLV |
|
Dosage form |
1, 2, 4 mg/kg/day for 8 week by injection. |
|
Application |
Mice treated with 1 or 2 mg/kg/day had an average ratio of spleen to body weight that was significantly lower than the infected with virus, untreated mice. Treatment with gemcitabine decreased MAIDS associated lesions in the lymph nodes. IgM levels from mice treated with 2 mg/kg/day of gemcitabine were significantly lower than that seen in the uninfected animals. Gemcitabine decreased provirus levels. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
