Altered expression of DNMT3A gene in B-cell acute lymphoblastic leukemia by mercaptopurine
Introduction: Current medications used for acute lymphoblastic leukemia (ALL) such as mercaptopurine target molecular factors involved in its onset and progression including DNA methyltransferases (DNMTs) because these enzymes are implicated in ...

The Asymptotic Number of Attractors in the Random Map Model [PDF]
The random map model is a deterministic dynamical system in a finite phase space with n points. The map that establishes the dynamics of the system is constructed by randomly choosing, for every point, another one as being its image.

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]
In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.
