We investigate the anticancer effect of a traditional Chinese medicine gambogic acid (GA) in human gastric cancer line SGC-7901 and further study the mechanism of apoptosis induction of GA.Low differential human gastric cancer line SGC-7901 were treated with GA at different doses and different times, the inhibitory rates were detected by MTT assay. Apoptosis induced by GA in SGC-7901 cells was observed...
This study was designed to assess E-cadherin (E-cad)and proliferating cell nuclear antigen (PCNA)expression as well as their clinicopathological significance in human non small cell lung cancers (NSCLCs). Possible molecular mechanisms of differentiation and metastasis of NSCLCs are discussed. Immuno-histochemical and immunofluorescence double staining were performed to examine the expression of E-cad...
To observe the influence of hyperthermia under different temperature on the growth, apoptosis of Human Lung Cancer cell of A549, H1299 to investigate the possible mechanism of apoptosis in lung cancer cell caused by p53 with different activity. Human lung cancer cell of A549, H1299 was heated under 40??C 42??C 44??C separately for 2 hours each in the water bath case. After the hyperthermia under different...
With the advance of immunology, immunogene therapy is becoming a possible therapeutic alternative to advanced cancer. The aim of tumor immunogene therapy is to enhance the immune response to tumors. Evidence suggests that CD80 (B7-1) and Interferon-gamma (IFN-gamma) play important roles in antitumor immunity induced by T lymphocyte. To study the antitumor immune effects of lung carcinoma vaccine modified...
AIM: In the present study, murine A549 Lung cancer cells were provided Lung cancer with different thermal dose invitro and invivo, thereafter we investigated the apoptosis, necrosis rates, and intratumoral microvessel density (MVD) to determine that microvessel damage plays an important role in the tumoricidal effect of Lung cancer. Methods: A549 Lung cancer cells were inoculated in the right hind...
