Recombinant Human PDGFB protein

• Cat.No.: PDGFB-528H
• Product Overview: Recombinant Human PDGFB protein was expressed in Escherichia coli.

Specification

• Description: Platelet-derived growth factor (PDGF) presenting in serum but absent from plasma was first discovered in animal study by Lynch and co-workers in the late 1980s. It is a disulfide-linked dimer consisting of two peptides-chain A and chain B. PDGF has three subforms: PDGF-AA, PDGF-BB, PDGF-AB. It is involved in a number of biological processes, including hyperplasia, embryonic neuron development, chemotaxis, and respiratory tubule epithelial cell development. The function of PDGF is mediated by two receptors (PDGFR-α and PDGFR-β).

• Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
• Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤-20 centigrade. Further dilutions should be made in appropriate buffered solutions.

Q&As

In what capacity does PDGFB contribute to the intricate processes of angiogenesis and vascular remodeling?

By potently stimulating the migratory and proliferative capabilities of smooth muscle cells and pericytes, PDGFB plays a pivotal role in regulating angiogenesis and orchestrating vascular remodeling events, thereby ensuring proper tissue perfusion and function.

How does PDGFB intricately contribute to the development and advancement of certain malignancies?

PDGFB signaling assumes a critical role in fueling tumor growth, angiogenesis, and metastasis. PDGFB, acting through its activation of PDGFRβ, elicits a pro-tumorigenic cascade that promotes tumor cell proliferation, survival, migration, and invasion, while concurrently fueling tumor vascularization and distant metastatic spread.

In what ways is PDGFB implicated in the pathogenesis and progression of fibrotic disorders?

PDGFB emerges as a significant contributor to the pathogenesis of fibrotic diseases by prompting fibroblast activation and proliferation. These dysregulated processes lead to excessive extracellular matrix deposition and subsequent tissue scarring. Furthermore, PDGFB exacerbates fibrosis through induction of myofibroblast differentiation.

What novel therapeutic avenues are being explored targeting the PDGFB/PDGFRβ signaling axis for interventional strategies?

Promisingly, preclinical and clinical studies have investigated diverse approaches targeting the PDGFB/PDGFRβ signaling axis for therapeutic intervention in fibrotic disorders and certain neoplastic conditions. Inhibitors directed against PDGFB or PDGFRβ have exhibited considerable potential, effectively blocking downstream signaling cascades activated by PDGFB, thereby hampering cell proliferation and angiogenesis.

How does PDGFB actively participate in the intricate mechanisms governing wound healing and tissue regeneration?

PDGFB, released by platelets and macrophages at inflammatory sites, acts as a key modulator in recruiting and activating fibroblasts. This activation not only promotes collagen synthesis but also initiates tissue remodeling, thus expediting the wound healing cascade and tissue integrity restoration.

What therapeutic strategies target PDGFB for disease treatment?

Several therapeutic strategies aim to target PDGFB for disease treatment. Inhibitors of PDGFB, such as tyrosine kinase inhibitors, have been developed and used in clinical settings. These inhibitors can selectively block the activation of PDGF receptors and inhibit downstream signaling pathways, thereby suppressing excessive cell proliferation and migration. Additionally, approaches targeting PDGFB expression, such as gene therapy or RNA interference, hold promise as potential treatments for diseases associated with PDGFB dysregulation.

How does PDGFB orchestrate cellular proliferation and growth in diverse tissues and organs?

PDGFB orchestrates cellular proliferative responses and drives growth by virtue of its ability to activate PDGFRβ, which in turn triggers downstream signaling cascades facilitating DNA synthesis and regulating critical cell cycle checkpoints.
