投射性认同指一个人诱导他人以一种限定的方式来作出反应的行为模式。体现在人际关系中,往往是甲方把内心中“好”或“坏”的客体投射到乙方身上,认为乙方“好”或“坏”,而乙方又接受了这一投射幻想,于是就以甲方所设想的方式来对待甲方。然后甲方又进一步验证了自己的假设,认为乙方就是他所认为的那样的人。根据上述定义,下列项属于投射性认同的是:( )A.

B.
严师方能出高徒
C.
虎父果然无犬子

【多选题】How do mitogens stimulate cell proliferation by inhibiting the Rb protein?
A.
As a general rule, mammalian cells will multiply only if they are stimulated to do so by extracellular signals, called mitogens, produced by other cells. If deprived of such signals, the cell cycle arrests in G 1 ; if the cell is deprived of mitogens for long enough, it will withdraw from the cell cycle and enter a nonproliferating state, in which the cell can remain for days or weeks, months, or even for the lifetime of the organism, as we discuss shortly.
B.
Escape from cell-cycle arrest—or from certain nonproliferating states—requires the accumulation of cyclins. Mitogens act by switching on cell signaling pathways that stimulate the synthesis of G 1 cyclins, G 1 /S cyclins, and other proteins involved in DNA synthesis and chromosome duplication. The buildup of these cyclins triggers a wave of G 1 /S-Cdk activity, which ultimately relieves the negative controls that otherwise block progression from G 1 to S phase.
C.
One crucial negative control is provided by the Retinoblastoma (Rb) protein. Rb was initially identified from studies of a rare childhood eye tumor called retinoblastoma, in which the Rb protein is missing or defective. Rb is abundant in the nuclei of all vertebrate cells, where it binds to particular transcription regulators and prevents them from turning on the genes required for cell proliferation.
D.
Mitogens release the Rb brake by triggering the activation of G 1 -Cdks and G 1 /S-Cdks. These complexes phosphorylate the Rb protein, altering its conformation so that it releases its bound transcription regulators, which are then free to activate the genes required for entry into S phase.
