Notch signaling sustains the expression of Mcl-1 and the activity of eIF4E to promote cell survival in CLL [PDF]
, 2015 In chronic lymphocytic leukemia (CLL), Notch1 and Notch2 signaling is constitutively activated and contributes to apoptosis resistance. We show that genetic inhibition of either Notch1 or Notch2, through small-interfering RNA, increases apoptosis of CLL ...

The EMBO Journal, 2015 The self‐renewal and differentiation of tissue stem cells must be tightly controlled. Unrestrained self‐renewal leads to over‐proliferation of stem cells, which may cause tumor formation, while uncontrolled differentiation leads to depletion of the stem cell pool.

American Economic Review, 1984 Economists have an instinctively negative reaction to any government program that creates a "notch," that is, a discontinuity in a budget constraint. For example, welfare programs like public housing are structured so that a finite lump of benefits is lost all at once when a household's income crosses a certain threshhold.
