Microenvironmental regulation of tumor progression and metastasis

Genetic and microenvironmental implications in prostate cancer progression and metastasis.

Prometastatic gene expression events occur during the early phases of prostate oncogenesis, even though overlaping with genes that induce primary cancer growth. Cytogenetic and genomic profiling analyses have identified many cancer-associated chromosomal abnormalities consisting mainly in losses in the early phases of sporadic primary prostate carcinoma. Metastatic genes are those in which gain...

Tumor progression and metastasis.

It is now widely accepted that cancer is attributed to the accumulation of genetic alterations in cells. Thus, to understand the molecular mechanisms of cancer metastasis, it is indispensable to identify the genes whose alterations accumulate during cancer progression as well as the genes whose expression is responsible for the acquisition of metastatic potential in cancer cells. Molecular anal...

The Role of Matrix Metalloproteinase-3 Functional 5A/6A Promoter Polymorphism in Tumor Cell Progression and Metastasis of Breast Cancer

In the human genome, chromosome 11 contains a cluster of matrix metalloproteinase (MMP) genes. Single nucleotide polymorphisms in the promoter region of MMP genes are important for MMP expression. A common adenine deletion polymorphism (5A) at position -1171 of the MMP-3 gene promoter (5´-AAAAAACCAT-3´ change to 5´-AAAAACCAT-3´) facilitates transcriptional factor binding and MMP-3 promoter acti...

Chemokines in tumor progression and metastasis

Chemokines play a vital role in tumor progression and metastasis. Chemokines are involved in the growth of many cancers including breast cancer, ovarian cancer, pancreatic cancer, melanoma, lung cancer, gastric cancer, acute lymphoblastic leukemia, colon cancer, non-small lung cancer, non-hodgkin's lymphoma, etc. The expression of chemokines and their receptors is altered in many malignancies a...
