FGF signalling facilitates cervical cancer progression.

Cervical cancer is one of the most frequently diagnosed cancers in women worldwide. While cervical cancer is caused by human papillomavirus (HPV), not all females infected with HPV develop the disease, suggesting that other factors might facilitate its progression. Growing evidence supports the involvement of the fibroblast growth factor receptor (FGFR) axis in several cancers, including gynecological.

Phase variable DNA repeats in influence transcription, translation, and protein sequence variation.

There are many types of repeated DNA sequences in the genomes of the species of the genus , from homopolymeric tracts to tandem repeats of hundreds of bases. Some of these have roles in the phase-variable expression of genes. When a repeat mediates phase variation, reversible switching between tract lengths occurs, which in the species of the genus most often causes the gene to switch between on and off states through frame shifting of the open reading frame.
