  2. HER2 - Wikipedia

    en.wikipedia.org/wiki/HER2

    HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family. But contrary to other members of the ERBB family, HER2 does not directly bind ligand. HER2 activation results from heterodimerization with another ERBB member or by homodimerization when HER2 concentration are high, for instance in cancer. [8]

    en.wikipedia.org/wiki/Epidermal_growth_factor...

    The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). In many cancer types, mutations affecting EGFR expression or activity could result in cancer. [6]

    The theory was initially proposed by Fred Hoyle in 1946, [1] who later refined it in 1954. [2] Further advances were made, especially to nucleosynthesis by neutron capture of the elements heavier than iron , by Margaret and Geoffrey Burbidge , William Alfred Fowler and Fred Hoyle in their famous 1957 B 2 FH paper , [ 3 ] which became one of the ...

    For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.
