Human AKT1 Knockout Cell Line-HCT116

AKT1, also known as protein kinase B (PKB), is a key enzyme in cell signaling pathways and plays a critical role in regulating various cellular processes. AKT1 belongs to the family of serine/threonine-specific protein kinases and is a key player in the PI3K/AKT/mTOR pathway, one of the most important and extensively studied signaling pathways involved in cell growth, proliferation, survival, and metabolism. When cells are stimulated by a range of growth factors, hormones, and other extracellular signals, the AKT1 protein is activated through phosphorylation. Upon activation, AKT1 translocates to different cellular compartments and phosphorylates various downstream substrates. This phosphorylation cascade can produce a variety of biological effects, including enhanced glucose uptake, increased protein synthesis, and inhibition of apoptosis, thereby promoting cell survival and growth.

The role of AKT1 in cell survival is particularly prominent in cancer. Abnormal activation of AKT1 is common in various types of cancer, resulting in uncontrolled cell proliferation and resistance to programmed cell death. This overactivation can result from mutation, amplification, or loss of negative regulators such as PTEN, a phosphatase that negatively regulates the PI3K/AKT pathway. As a result, AKT1 is considered an important oncogene, and the PI3K/AKT pathway has become a focus of cancer research and therapeutic intervention. Several inhibitors targeting different components of this pathway are currently in development or clinical use, aiming to prevent cancer progression by disrupting aberrant AKT1 signaling.
