Success in academia is hypothesized to require specific phenotypes.


Success in academia is hypothesized to require specific phenotypes.

In order to understand how such unusual traits arise, we use mutant clones to identify the molecular events that occur during the transition from a graduate student to professor. A pool of graduate students was subjected to several rounds of random mutagenesis followed by selection on minimal money media in the absence of dental insurance.

Students surviving this selection were further screened for the ability to work long hours with vending machine snacks as sole carbon source; clones satisfying these requirements were dubbed "post-docs". In order to identify assistant professors from amongst postdocs, this pool was further mutagenized, and screened for the ability to turn esoteric results into a 50-minute seminar.

Finally, these assistant professors were evaluated for their potential to become full professors in two ways: first they were screened for overproduction and surface display of stress proteins such as Hsp70. Assistant professors that displayed such proteins (so called "stressed out" mutants) were then fused to M13 coat protein, displayed on phages and passed over a friend and family members column, to identify those that were incapable of functional interactions. These were called full professors. Although these mutants arose independently, they share striking phenotypes. These included the propensity to talk incessantly about their own research, the inability to accurately judge the time required to complete bench work, and belief that all their ideas constituted good thesis projects. The linkage of all these traits suggests that these phenotypes are co-ordinately regulated. Preliminary experiments have identified a putative global regulator. Studies are currently being conducted to determine if overexpression of this gene product in post-docs and grad students can speed up the grad student-full professor evolutionary process.

私 「これ、面白いでしょ?」


今日の教訓 Hsp70発現してますよーーー。
