Article Title: The ERK cascade inhibitors: Towards overcoming resistance.
Article Snippet: The RAS–ERK pathway plays a major regulatory role in various cellular processes.. This pathway is hyperactivated and takes an active part in the malignant transformation of more than 85% of cancers.. The hyperactivation is mainly due to oncogenic activating mutations in the pathway’s components RAS, RAF and MEK, but also due to indirect mechanisms in cells transformed by other oncogenes.

Article Title: MEK inhibitors in cancer treatment: structural insights, regulation, recent advances and future perspectives.
Article Snippet: MEK1/2 are critical components of the RAS–RAF–MEK–ERK or MAPK signalling pathway that regulates a variety of cellular functions including proliferation, survival, and differentiation.. In 1997, a lung cancer cell line was first found to have a MEK mutation (encoding MEK2P298L).. MEK is involved in various human cancers such as non-small cell lung cancer (NSCLC), spurious melanoma, and pancreatic, colorectal, basal, breast, and liver cancer.

Article Title: The ERK cascade inhibitors: Towards overcoming resistance.
Article Snippet: The RAS–ERK pathway plays a major regulatory role in various cellular processes.. This pathway is hyperactivated and takes an active part in the malignant transformation of more than 85% of cancers.. The hyperactivation is mainly due to oncogenic activating mutations in the pathway’s components RAS, RAF and MEK, but also due to indirect mechanisms in cells transformed by other oncogenes.
