Abstract

High mobility group box 1 (HMGB1), a non-histone nuclear protein, was associated with a variety of biological important processes, such as transcription, differentiation, extracellular signaling. As a cytokine or inflammatory mediator, more and more data showed that HMGB1 was involved in inflammatory diseases, cancers or autoimmune disease. However, few data focused on nucleic or cytoplasmic function of HMGB1. Therefore, the present study focused on cancer cells biological characteristics following HMGB1 silence. HMGB1 siRNAs were designed and chemically synthesized, and then transfected into the breast cancer cell line MCF-7 with lipofectamine 2000. The transcription and translation level of HMGB1 expression, proliferation, apoptosis, migration of MCF-7 were determined. The results demonstrated that HMGB1 silence inhibit invasion and migration and promote apoptosis of human breast cells; which indicated that HMGB1 silence might be a potential therapy targets.

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
