The similarity in Vpr-mediated G2 cell cycle arrest profiles after depletion of CUL4A or CUL4B prompted us to confirm that we could distinguish between CUL4A- and CUL4B-specific effects in our system. Zou et al. demonstrated previously that the replication licensing factor CDC6 is positively regulated by CUL4B but not by CUL4A (78). We therefore induced the expression of CUL4A- or CUL4B-specific shRNA in cells that were stably transduced with the respective expression constructs. As in the previous work, cells depleted of CUL4B, but not those depleted of CUL4A, expressed lower levels of CDC6 (Fig. 2C). In summary, in our HEK293T system, depletion of CUL4A or CUL4B did not impact HIV-1 infectivity or cell viability. Furthermore, while Vpr-mediated G2 cell cycle arrest proceeded in the absence of either CUL4A or CUL4B, the CUL4B-specific impact on CDC6 was preserved.

Lin had noticed a gap between himself and mainlanders his age. It made doing business difficult sometimes. Perhaps one of the differences, he said, was the amount of education. Despite pressing, he said little else; it was something he felt uncomfortable or maybe incapable of describing.

Friston says his work has two primary motivations. Sure, it would be nice to see the free energy principle lead to true artificial consciousness someday, he says, but that’s not one of his top priorities. Rather, his first big desire is to advance schizophrenia research, to help repair the brains of patients like the ones he knew at the old asylum. And his second main motivation, he says, is “much more selfish.” It goes back to that evening in his bedroom, as a teenager, looking at the cherry blossoms, wondering, “Can I sort it all out in the simplest way possible?”
