Abstract

The global burden of cancer have encouraged oncologists to develop novel strategies for treatment. Present study was proposed to develop Arginyl-glycyl-aspartic acid (RGD)-containing nanostructured lipid carriers (NLC) as a delivery system for improving the anticancer capability of epigallocatechin gallate (EGCG) on breast cancer cell line by attaching to integrin superfamily on cancer cells. For this purpose, RGD-containing EGCG-loaded NLC were prepared by hot homogenization technique and characterized by different techniques. Then, cytotoxic and apoptotic effects of prepared nanoparticles and their uptake into cells was evaluated. As results, the nanoparticles with particle size of 85 nm, zeta potential of -21 mV, encapsulation of 83% were prepared. Cytotoxicity and apoptosis experiments demonstrated that EGCG-loaded NLC-RGD possessed greatest apoptotic activity. Furthermore, it has been shown that, EGCG-loaded NLC-RGD causes cell cycle arresting more effective than EGCG. Therefore, loading EGCG into NLC-RGD make it more effective in both targeting and accumulation into tumour cells, which results from specialized uptake mechanism by adhesion to αvβ3 integrin. The results strengthen our hope that loading EGCG into RGD-contain...Continue Reading

Breast Cancer: Therapeutic Approaches

Several different therapeutic approaches are used to treat breast cancer. These include chemotherapy, hormonal therapy, targeted therapy, and Immunotherapy. Discover the latest research on breast cancer therapeutic approaches here.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

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.

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
