c. HA 16
d. HA 17

ANSWER: HA 15
 
Scientists have synthesised a new drug that they say can treat melanoma, a highly aggressive form of skin cancer.
  • The drug, known as HA15, reduces the viability of melanoma cells without being toxic for normal cells.
  • Melanoma affects melanocytes, the cells responsible for the synthesis of melanin, which gives skin its colour. The tumour progresses in three stages: radial growth, in which the cells proliferate in a disordered manner in the epidermis; the vertical growth phase, which involves invasion of the dermis, and finally the metastatic phase, corresponding to the dissemination of the cancer cells in the peripheral tissues.
