1.Clinical Value of Growth Factors and Their Receptors for the Metastasis and Prognosis of Breast Cancer
Chinese Journal of Clinical Oncology 2010;37(4):234-237
Through its high affinity with membrane receptors, growth factors promote tumor growth, metastasis and an-giogenesis, induce the change of tumor microenvironment and regulate immune response. It has been demonstrated that the serum protein levels of epidermal growth factor and its receptor, transforming growth factors and their receptors, insu-lin-like growth factors, and angiogenesis factors may have predictive value for metastasis and prognosis of breast cancer. Detecting serum levels of growth factors and their receptors which have synergistic effect or interaction with each other may be helpful for predicting the metastasis and progression of breast cancer.
2.Progress of research on predicting breast cancer prognosis based on multi-gene expression levels
Chinese Journal of Clinical Oncology 2013;(13):807-810,814
Breast cancer is one of the most common cancers in women. Current clinical prognostic indicators and practice guide-lines show that almost 70% of node-negative and 30% of lymph node-positive breast cancer patients can survive 5-10 years without dis-tant metastasis after surgery. Patients also unnecessarily suffer the side effects of chemotherapy. Assays on multi-gene expression levels as prognosis prediction indicators have been successfully used to predict the prognosis of breast cancer patients because of the abnor-mal expression levels of a series of metastasis-related genes in cancer cells with high metastatic potential. In this review, we highlight the progress of research on predicting breast cancer prognosis based on multi-gene expression levels detected by microarray and qRT-PCR methods.

Objective To investigate the genetic association between polymorphisms of Ser447Stop in lipoprotein lipase (LPL) gene and ischemic stroke. MethodsA case-control study was performed in 563 acute ischemic stroke patients and 320 controls. LPL Ser447Stop genotypes in the subjects were detected by polymerase chain reaction and restriction fragment length polymorphism assay. The frequencies of the alleles in each group were statistically analyzed with Student t-test. ResultsNo significant difference was found in the frequency of G allele of LPL Ser447Stop polymorphism between the case and the control. When subjects were divided into 2 subgroups of cerebral thrombosis infarction and lacunar infarction, the frequency of G allele was significantly higher in the cerebral thrombosis infarction group (9. 7% ) than that in the control (6. 6%, χ2= 3. 99,P = 0. 045 ), and an increased risk for thrombosis infarction was suggested in the G allele ( OR = 1. 510, 95% CI 1. 012--2. 261 ). ConclusionThe G allele in polyim Ser447Stop in LPL may be associated with increased risk of cerebral thrombosis infarction.
