Usually a subject which is not a laughing matter, scientists say they have found a smiley face in a cancer-causing protein.
The beta-catenin protein causes cancer by moving into the cell nucleus, the round "face" or centre of the cell, and activating a set of genes that transform normal cells into tumour cells.
In this highly-unusual image, beta-catenin (green) was monitored moving into the nucleus, the round shape in the centre. The dark patches in the nucleus that bear an uncanny resemblance to a smiley face, with eyes and a mouth, are actually parts of the nucleus where the beta-catenin cannot enter.
"We spend 90 per cent of our time going down dead ends, and sometimes you feel as though a disease is having a cackle at your expense," says Dr Beric Henderson, head of the gene expression laboratory at Westmead Millennium Institute for Medical Research, University of Sydney.
