Product Description

Biological Activity

Description Gemcitabine is a very potent and specific deoxycytidine analogue, used as chemotherapy.
In vitro Gemcitabine results in 50% inhibition of growth in the CCRF-CEM human leukemia cell culture assay with IC50 of 1 ng/ml. Gemcitabine combined with deoxycytidine provides about a 1000-fold decrease in biological activity. [1] Gemcitabine combined with C225 results in additive cytotoxic effects that increased with increasing gemcitabine concentrations in human pancreatic carcinoma L3.6pl cells. [2] Gemcitabine combined with Cisplatin results in synergistic effect in wild-type A2780 and cisplatin-resistant ADDP cells. [3]
In vivo Gemcitabine combined with C225 results in growth inhibition, tumor regression, and abrogation of metastasis in L3.6pl tumors established in the pancreas of nude mice. Gemcitabine treatment alone reduces median tumor volume from 538 to 152 mm3. Gemcitabine reduces the production of vascular endothelial growth factor and interleukin 8 in gemcitabine-treated tumors. [2] Gemcitabine is able to dramatically and specifically reduces the number of myeloid suppressor cells found in the spleens of animals bearing large tumors with no significant reductions in CD4(+) T cells, CD8(+) T cells, NK cells, macrophages, or B cells. [4] Gemcitabine combined with curcumin shows significant reductions in volume (P = 0.008 versus control; P = 0.036 versus gemcitabine alone), Ki-67 proliferation index (P = 0.030 versus control), NF-kappaB activation, and expression of NF-kappaB-regulated gene products (cyclin D1, c-myc, Bcl-2, Bcl-xL, cellular inhibitor of apoptosis protein-1, cyclooxygenase-2, matrix metalloproteinase, and vascular endothelial growth factor) compared with tumors from control mice treated with olive oil only. Gemcitabine combined with Curcumin is also highly effective in suppressing angiogenesis as indicated by a decrease in CD31(+) microvessel density. [5]

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Method Immunofluorescence
Cell Lines HeLa cells
Concentrations 100 nM
Incubation Time 72 h
Results To finally investigate whether incorporation of drugs into RNA could be a general mechanism inducing SG assembly, we tested other chemotherapeutics known to incorporate into RNA, such as 5-azacytidine and 6-thioguanine, or as control, chemotherapeutics known to incorporate mainly into DNA, such as trifluorothymidine (TFT) or gemcitabine. HeLa cells treated with 5-azacytidine and 6-thioguanine displayed TIAR-positive foci, whereas HeLa cells treated with TFT or gemcitabine did exhibit such foci even with higher concentrations applied.
