RESUMO
Remodeling and spacing factor-1 (Rsf-1), firstly discovered in 1998 and located in the nucleus, is one of the most commonly amplified gene and its protein molecular weight is about 240 ×103. The interaction between Rsf-1 and human sucrose non-fermenting protein 2 homologue (hSNF2H) changes the cell growth signals and environment, which is inclined to cause the cells loss of the normal regulation, leading to the abnormal proliferation and occurrence of tumors. Recent study has shown that Rsf-1 is closely related to the prognosis of a lot of human malignancies, such as genitourinary system tumors, gastrointestinal tumors, head and neck cancer, non-small cell lung cancer and glioma.
RESUMO
The level of the in vitro synthesis of secretory immunoglobulin A (SIgA) was determined by the sissue culture of the endoscopically biopsied gastric mucosa from patients with noncancerous gastric diseases. The amount of SIgA synthesis in chronic superficial gastritis (4.35?0.32?g/mg) and chronic atrophic gastritis (4. 82?0. 22ug/mg) was higher than that in the normal stomach (2.76?0.21 ?g/mg) (p
RESUMO
A new group of gastric cancer associated antigens in sera of patients with rectal cancer, benign diseases and normal human were detected by MG series monoclonal antibodies against gastric cancer. The average values of normal persons plus 3 standard deviations was set as the highest limit of normal value. The positive rate were 69.7% (23/33) in sera of patients with rectal cancer, and 4%(1/25) in sera of patients with benign diseases. The values of MG-Ags were decreased to normal level 8-10 days after surgical removal in 5 patients of rectal cancer. The results of test suggest that determination of MG-Ags in serum of patients might be helpful in the diagnosis of rectal carcinoma.
