Objective: To investigate the possible association between the allelic variation of LAPTM4B and the genetic susceptibility of lung cancer. Methods: The genotype of LAPTM4B was analyzed in 134 unrelated healthy adult individuals and 166 patients with lung cancer by utilizing polymerase chain reaction based on special primers. The genotypical distribution of LAPTM4B was analyzed by ? 2 test. Results: The allelic frequencies of the *2 were 40.1% and 28.0% in the lung cancer group and the healthy control group respectively, which was significantly different between the two groups (P 0.002). There was a significant difference in the overall genotypical distribution between the patients and the controls (P0.005). The risk of suffering from lung cancer was increased 1.91 times in the individuals of the *1/2 genotype (95%CI: 1.178-3.110) and 3.26 times in the individuals of the *2/2 genotype of LAPTM4B (95%CI:1.338-7.929) compared with the *1/2 genotype. No association was observed between the genotypical distribution of LAPTM4B and the clinical information on patients of lung cancer such as gender, age, pathological type, differentiation classification of TNM and infection of HBV. Conclusion: This study suggests that the allele *2 of LAPTM4B might be the risk factor of lung cancer, which could be associated with genetic susceptibility of lung cancer.
3.Apoptosis and its modulation in type Ⅰ diabetes mellitus
Chinese Journal of Pathophysiology 1999;0(09):-
Apoptosis, also known as programmed cell death,is a normal process contributing to tissue tumor during development and in the adult.During development apoptosis is involved in tissue homeostasis and eliminating nonfunctional,superfluous or harmful cells.It is an active process controlled by some gene and factors such as caspases, bcl-2, Fas/FasL and NO.Type 1 diabetes mellitus is regarded as a chronic autoimmune disease resulting from progressive destruction of insulin-producing ?-cells in the pancreas.The relationship between apoptosis with its modulation and type 1 diabetes mellitus was reviwed.
