De novo lipogenesis protects dormant breast cancer cells from ferroptosis and promotes metastasis.

Dormant disseminated tumor cells (DTCs) remain viable for years to decades before establishing a clinically overt metastatic lesion. DTCs are known to be highly resilient and able to overcome the multiple biological hurdles imposed along the metastatic cascade. However, the specific metabolic adaptations of dormant DTCs remain to be elucidated.

[An unusual location of urethral leiomyoma, the most common pelvic tumour in the female].

Urethral leiomyoma is a rare benign mesenchymal tumour arising from the smooth muscle of the urethra. It most often appears in females of reproductive age. Approximately 100 cases have been reported to date.
