Article Title: α-Klotho Expression in Human Tissues

doi: 10.1210/jc.2015-1800

Figure Lengend Snippet: α-Klotho isoforms, sequence, and Western blot. A, Structure of the two isoforms of α-Klotho. Isoform 1 represents the full-length protein and contains a signal sequence domain (SS), two homologous domains (KL1, KL2), a short transmembrane domain (TM), and a short cytoplasmic tail. Shown is the site of the epitope for the antibody used in our experiments: AA 800 to 900, KL2. This epitope is absent from Isoform 2, a soluble, secreted protein that arises from alternative RNA splicing and contains only AA 1–549, and where the terminal 15 residues are replaced by the sequence shown. B, The full-length α-Klotho protein sequence of 1012 AA is shown, with KL1 and KL2 shown in red and green respectively, and TM highlighted (black). The peptides giving rise to the PRM signature are also shown (bold typeface; common to isoforms 1 and 2, red; exclusive to full-length α-Klotho, isoform 1, blue). C and D, Western blot analysis of cell lysates (C) and tissues (D) supports the presence of the full-length α-Klotho. Full-length rh α-Klotho protein (rh-α-Klotho). EC, epithelial cells.

Article Title: α-Klotho Expression in Human Tissues

doi: 10.1210/jc.2015-1800

Figure Lengend Snippet: α-Klotho protein expression and distribution in human epithelial and reproductive tissues. IHC, positive staining (brown) was found in all the cellular layers of the epidermis (A) and appendage tissue such as hair follicle and sebaceous gland (B). Intestinal expression was primarily found in epithelial cells as illustrated in jejunum (C) and colon (D). In reproductive tissues, positive staining was found in epithelial Sertoli cells (E), testosterone producing Leydig cells (illustrated with white arrows) of the testis (F), and epithelial cells of the prostate gland G). H–K, In mammary tissue (H), endometrium of uterus (I), and endometrium of salpinx (K), the epithelial cell layer was staining strongly for α-Klotho protein; insets are larger magnifications of the epithelial layer. n ≥ 5 for each tissue.
