Using a STAT3 antibody in chromatin immunoprecipitation (ChIP)

Signal transducer and activator of transcription 3 (STAT3) is an important oncogenic transcriptional factor that mediates tumor induced immune suppression.  Specifically, STAT3 transmits signals from cytokines and growth factor receptors in the plasma membrane (PM) to the nucleus, where they alter gene transcription.  Because of this transcriptional regulatory role, STAT3 also plays a part in regulating transcription of many critical genes that are involved in apoptosis, cell differentiation, immune response, tumor formation and more.  Using a

Altered expression of BCL2 in cancer

Similar to other cell processes, the balance between cell survival and cell death is an important equilibrium that when altered expression of genes can lead to a variety of disease.

AKT1 - Regulating cell growth and survival through phosphorylation

AKT1 is a serine/threonine protein kinase with homology to protein kinase A (PKA) and protein kinase C (PKC). AKT1 contains the central kinase domain sandwiched between a pleckstrin homology domain and a regulatory domain (1). AKT1 is regulated by receptor tyrosine kinase pathways and is activated in a PI3K-dependent manner following growth factor stimulation (1).

Akt1 - a central player in cell survival signaling

Akt1 is one of three isoforms of Akt belonging to the AGC family of serine/threonine kinases (Akt1, Akt2, and Akt3). All Akt isoforms contain an N-terminal Plekstrin Homology (PH) domain, a C-terminal regulatory domain, and a central catalytic kinase domain (1). Akt is a major downstream target of the PI3-K signaling pathway. The Akt1 isoform is fully activated by phosphorylation at three sites- T308, T450, and S473. Akt1 resides in an inactive state due to intramolecular interactions between the PH domain and the kinase domain.


AKT1, Scene 1: The Cell Must Go On

Akt1 is a serine/threonine-specific protein kinase involved in many cellular signaling pathways. The major function of this kinase is to mediate cell survival, but it also plays key roles in various other cellular functions such as glycogen synthesis and cell growth. Akt1 acts as a transducer for growth factor receptors that modulate phosphatidylinositol 3-kinase (PI3K) activity. Akt is believed to be a factor in cancer as the tumor suppressor phosphatase and tensin homolog (PTEN) was found to antagonize both PI-3 kinase and Akt kinase activity.

Caspase 9 and Mitochondrial Apoptosis Regulation

Caspase 9 (also termed ICE-LAP6, Mch6, Apaf-3) is a member of cysteine protease family of caspases and is encoded by the CASP9 gene in humans. Caspase-9 is involved in mitochondrial apoptosis pathway and is an initiator caspase.

Mapping Signal Transduction with mTOR Antibodies

The protein encoded by mTOR (mammalian target of rapamycin), also known as dTOR in Drosophila, belongs to a family of phosphatidylinositol kinase-related kinases. These kinases regulate fundamental processes of cell growth, proliferation, metabolism

EZH2: Epigenetic Regulation Made Easy!

Enhancer of Zeste homolog 2 (EZH2) is the methyltransferase enzyme responsible for trimethylating lysine 27 on histone H3 to produce H3K27Me3. EZH2 is a polycomb group protein that is an essential epigenetic regulator that is often found deregulated in a wide variety of malignant cancer types.

Antibodies Targeting the mTOR Pathway for Many Diseases

The mammalian target of rapamycin (mTOR) is a downstream effector of the phosphatidylinositol 3-kinase (PI3K)/Akt (protein kinase B) signaling pathway that mediates cell survival and proliferation. It is increasingly apparent that mTOR signaling impacts most major cellular functions.

AKT Antibody Assays: A Complex Area with an Easy Solution

We at Novus Biologicals place a lot of emphasis on the kinase signaling pathways. Kinases, or phosphotransferase enzymes play a key role in phosphorylation signaling. Over 500 human protein kinases have so far been discovered. They play essential roles in glucose metabolism, apoptosis, lipid transport, cell migration, cellular differentiation and other cellular functions.
