hVin monoclonal antibody

Description: Monoclonal antibodies raised against human Vinculin purified from human uterus. Specifically stains Vinculin at cell-cell and cell-substrate contacts in tissue and cultured cells. Good reactivity is obtained with human, bovine, chicken, dog, rat mouse, turkey and xenopus Vinculin.

Vinculin is a cytoskeletal protein associated with the cytoplasmic faces of both cell-cell and cell-extracellular matrix adherens-type junctions. It functions as one of

several interacting proteins involved in anchoring F-actin to the membrane.

176-177 - Monoclonal antibodies to phospho-ERK/Map Kinase

Description: Monoclonal antibodies raised against peptides containing the 11 amino acids, HTGFLTEYVAT, corresponding to the ERK activation loop either Tyr -phosphorylated (ERK-PY193), or Thr-phosphorylated (ERK-PT115).

ERK belongs to the family of mitogen-activated protein kinases (MAPKs) and is an important component in many intracellular signaling events. ERK is phosphorylated and activated by the upstream kinases, MEK1 and MEK2 on regulatory Threonin (Thr) and tyrosine (Tyr) residues, which are localized in the activation loop of ERK.

Monoclonal antibody to Runx-3

Description: Monoclonal antibody to Runx-3 raised against the Runx3 peptide TPSTPSPRGSLSTTSHF. Available clones: 62, H8.

Runx-3 (Runt-related transcription factor 3) is a transcription factor, and a master regulator of lineage specific gene expression in several important developmental pathways. It binds to the core DNA sequence 5'-YGYGGT-3' found in a number of enhancers and promoters, and can either activate or suppress transcription. It functions as a tumor suppressor, and is frequently deleted or transcriptionally silenced in cancer.

Cellular senescence is a permanent cell cycle arrest induced by damage or stress applied on proliferating cells. In a cell autonomous manner, senescence is a potent barrier to tumorgenesis and contributes to the cytotoxicity of some anti-cancer drugs. However, with age senescence cells accumulate and promote a number of pathological conditions. Therefore the elimination of senescent cells is desired in order to prevent tumor- and inflammation- related pathologies and also to inhibit tissue ageing.
Today, our understanding of the mechanisms regulating the viability of senescent cells is limited. It has been suggested that senescent cells are resistant to apoptosis. Therefore, senescent cells elimination may be achieved by modifying the resistance to apoptosis of these cells.
Here the researches demonstrate the first feasible therapeutic approach that leads to eradication of senescent cells. Combination of direct induction of apoptosis in senescent cells with induction of cell death by pro-inflammatory repose induce by p21 knockdown will lead to reduction of viable senescent cells.

Applications


  • A therapeutic impact on inflammatory and fibrotic disease
  • Therapy for age-related disease such as type 2 diabetes, Alzheimer’s disease, Atherosclerosis, cataracts, Chronic obstructive pulmonary disease (COPD), and Osteoporosis

Advantages


  • Effective elimination of senescent cells- removal of senescent cells can prevent or delay tissue dysfunction and extend health span
  • Does not damage normal cells even at high concentrations

Technology's Essence


Researches demonstrated that the anti-apoptotic proteins Bcl-xL and Bcl-w level were elevated in senescence cells of both human and mouse origin. A subsequent study, in which Bcl-xL and Bcl-w were knocked down by siRNA, revealed that a combined knock down of Bcl-xL and Bcl-w had synergic effect, resulting in reduction of 50% in cell viability. Thus the increased level of anti-apoptotic proteins Bcl-xL and Bcl-w may account for the apoptotic resistance of senescent cells. p21 knockdown induced pro-inflammatory response and cell death in senescent cells.
Overall, the researchers show that combined inhibition of the anti-apoptotic proteins Bcl-xL and Bcl-w allows specific elimination of senescent cells and might be used to treat diseases where senescent cells are present. The researchers also found that the same effect might be achieved by reducing the expression of p21 in senescent cells. Integrating both approaches propose a more effective therapy.
