- Western blot analysis was performed on whole cell extracts (30 µg lysate) of Hep G2 (Lane 1), HeLa (Lane 2), A-431 (Lane 3), Caco-2 (Lane 4) Caco-2 treated with IL-6 (100ng/ml for 24hr) (Lane 5), A-375 (Lane 6) and K-562 (Lane 7). The blot was probed with Anti-Cytokeratin 18 Polyclonal Antibody (Product # PA5-14263, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). A 48 kDa band corresponding to Cytokeratin 18 was observed across the cell lines tested. Also, the protein expression increased in Caco-2 cell line upon IL-6 treatment and was not detected in A-375 which is reported to be negative for Cytokeratin 18.

- Immunofluorescence analysis of Cytokeratin 18 was performed using 70% confluent log phase Hep G2 cells. The cells were fixed and permeabilized with ice-cold acetone and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Cytokeratin 18 Polyclonal Antibody (Product # PA5-14263) at 1:50 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415). Panel d represents the merged image showing cytoskeletal localization. Panel e represents control cells with no primary antibody to assess background. Panel f shows the negative cell line A-375 with no Cytokeratin 18 expression. The images were captured at 60X magnification.

H&E, x40, scale bar = 50 um. A few tumour cells contain intracytoplasmic, paranuclear vacuoles (arrowheads). d . H&E, x60, scale bar = 20 um. Tumour cells demonstrate. e nuclear and cytoplasmic YAP1 expression (immunoperoxidase, x20), f weak cytoplasmic MUC1 expression (immunoperoxidase, x20) and g they are focally positive for GFAP (immunoperoxidase, x20) and h cytokeratin 18/CK18 (immunoperoxidase, x10). Reactive astrocytes surrounding the lesion are also GFAP-positive ( g --immunoperoxidase, x20).
