Knockout Validated: MUC1 Antibody - BSA Free [NBP1-60046]

Knockout Validated: MUC1 Antibody - BSA Free [NBP1-60046] - MUC1 Antibody [NBP1-60046] - C57BL/6 Muc1 KO mice and WT mice were undergoing intranasal instillation of 75 ug of lipopolysaccharide (LPS) at day 1. Between days 2 and 3, animals were exposed to cigarette smoke (or control air) of 6 cigarettes followed by 8 cigarettes (or control air) at days 4 and 5, and 10 cigarettes (or control air) at day 6. Vehicle or dexamethasone at 3 mg/kg/day and 10 mg/kg/day was administered orally once a day between day 1 and 6. Animals were sacrificed at day 6 and lungs were homogenized to analyze protein expression of Muc1 cytoplasmic tail (CT). Protein expression was normalized to B-actin.

Knockout Validated: MUC1 Antibody [NBP1-60046] - Dexamethasone induces Muc1-CT nuclear translocation and co-localization with GRa in bronchial epithelium of WT mice but not in MUC1 KO mice. C57BL/6 Muc1 KO mice and WT mice were undergoing dexamethasone 10 mg/kg/day (orally) for 6 days. Animals were sacrificed at day 6 and lungs were fixed in paraformaldehyde (4%) for 48 h and embedded. Lung slices were immunostained with MUC1-cytoplasmic tail (CT) (red) and glucocorticoid receptor alpha (GRa) antibodies (green) with rhodamine/fluorescein secondary antibodies. DAPI was used to mark cell nucleus. Representative con-focal images are showed. Scale bar: 5 um.

Background: MUC-1

Mucin 1 (MUC1), also known as episialin, EMA (epithelial membrane antigen), PEM (polymorphic epithelial mucin), and CA-15-3 antigen, is a membrane-bound type I transmembrane glycoprotein (1,2). MUC1 is typically expressed in the luminal or glandular epithelial cells of the gastrointestinal tract, breast, lungs, and more, and is often overexpressed in epithelial cancers, but also serves a protective role against infection and helps regulate inflammatory response (2,3). Human MUC1 is 1255 amino acids (aa) in length with a theoretical molecular weight of 122 kDa; however, depending on the amount of glycosylation can weigh between 250 - 500 kDa (2,4). Structurally, MUC1 consists of a N-terminal domain which contains a signal peptide, a variable number tandem repeat region (VNTR), and a SEA domain, as well a C-terminal domain which has the extracellular domain (ECD), transmembrane domain (TMD), and cytoplasmic tail (CT) (2,3). The VNTR is comprised of between 25 - 125 repeats of a 20 aa conserved sequence (3). MUC1 is heavily O-glycosylated in the VNTR and has moderate N-glycosylation sites following the VNTR and in the ECD (2). Glycosylation contributes to MUC1's functional properties (2). The MUC1 gene contains seven exons, giving rise to several MUC1 isoforms as a result of alternative splicing (2).

Overexpression of mucins, including MUC1, is a feature of many epithelial cancers (1,3,5,6). The presence of truncated glycan structures called tumor-associated carbohydrate antigens (TACAs) on MUC1 play a role in cancer progression and a loss of apical-basal polarity (5). Carbohydrate-binding partners called lectins are the primary binding partners of TACAs that give rise to the pro-tumor microenvironment and metastasis (5). Given this unique feature, TACAs are a potential target for cancer immunotherapies (5). There are a number of vaccines, drugs, and antibodies targeting MUC1 for treatment of a variety of cancers including breast, lung, and prostate (6). In addition to a role in cancer progression, MUC1, and specifically the CT portion, has been shown to have a positive, anti-inflammatory role in a variety of lung and airway infections (7).
