As a signaling molecule, LT-α (TNF-β, Tumor Necrosis Factor beta) is involved in the regulation of cell survival, proliferation, differentiation, and apoptosis[1]. TNF-β plays an important role in innate immune regulation and its presence has been shown to prevent tumor growth and destroy cancerous cell lines[2]. In contrast, unregulated expression of TNF-β can result in a constantly active signaling pathway, thus leading to uncontrolled cellular growth and creation of tumors[1]. Hence depending on the context, TNF-β may function to prevent growth of cancer cells or facilitate the development of tumors. Furthermore, TNF-β effects depend on the type of organ it acts upon, type of cancer cells, cellular environment, gender, and time of effect during an immune response[2].

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
