Detection of Human Progranulin/PGRN by Western Blot

Detection of Human Progranulin/PGRN by Western Blot

Specificity of PGRN antibodies and detection of multiple endogenous GRNs. A, Whole-cell lysates from HAP1 WT and HAP1 PGRN KO cells, either reduced (+TCEP) or nonreduced (-TCEP), were analyzed for PGRN antibody specificity by immunoblot. The bottoms of the blots (<15 kDa) were exposed longer to reveal levels of endogenous GRNs. B, Whole-cell lysates from HEK293T WT and N-TAP PGRN stable overexpressing (PGRN) cells were analyzed as in A by immunoblot. C, Representative immunofluorescent images of HAP1 PGRN KO and WT cells stained with the corresponding PGRN antibodies as in A and B. Scale bar, 10 µm. Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/28828399), licensed under a CC-BY license. Not internally tested by R&D Systems.

Background: Progranulin/PGRN

Progranulin, also known as acrogranin, PC cell-derived growth factor (PCDGF) and epithelin/granulin precursor, is a ubiquitously expressed, 88 kDa, secreted glycoprotein (1‑3). Structurally, it does not belong to any of the well-established growth factor families (4). Human Progranulin is 593 amino acids (aa) in length and contains a 17 aa signal sequence and 5 potential sites for N-linked glycosylation. It has a highly repetitive organization, containing seven tandem copies of a 55‑57 aa consensus motif that contains 12 conserved cysteine residues: VxCx5-6Cx5CCx8CCx6CCxDx2HCCPx4Cx5-6Cx2 (1). There is one alternate splice form for human Progranulin. This has a deletion of aa corresponding to aa 377‑531 of the standard form. Progranulin is secreted as a full length form (2, 4), and may undergo proteolysis leading to the release of numerous peptides made from the seven tandem repeats, called the granulins (5‑7). Human Progranulin shares 75% aa sequence identity with mouse and rat Progranulin. Progranulin is involved in the regulation of cellular proliferation, as well as differentiation, development, and pathological processes (4). It has been isolated as a differentially expressed gene during mesothelial differentiation (8), macrophage development (9), the development of rheumatoid arthritis and osteoarthritis (10), sexual differentiation of the brain (11), and has also been shown to be a mediator of cartilage proliferation and of wound response and tissue repair (4, 12‑13). High levels of Progranulin expression have been found to be associated with several human cancers and are believed to contribute to tumorigenesis in breast cancer, clear cell renal carcinoma, invasive ovarian carcinoma, glioblastoma, adipocyte teratoma, and multiple myeloma
(4‑5, 12, 14‑19). In addition, mutations in the Progranulin gene are a cause of frontotemporal dementia, and increased expression of Progranulin is seen in activated microglia in many neurodegenerative diseases including Creutzfeldt-Jakob disease, motor neuron disease and Alzheimer's disease (20). Mutations in Progranulin causing neurodegenerative disease indicate that Progranulin is important for neuronal survival (20).
