Author Tom Pollard: “I hope readers will enjoy movies from our 1970 JCB paper showing dramatic cytoplasmic movements in cell-free extracts. Electron micrographs in the paper related these movements to the assembly of actin filaments. This addendum is a tribute to my very generous mentor Sus Ito.”

#Addendum to 1970 paper, “CYTOPLASMIC FILAMENTS OF AMOEBA PROTEUS: I. The Role of Filaments in Consistency Changes and Movement,” includes eight video sequences originally recorded on 16-mm films. No technology was available at the time to include this data. 🎞️ rupress.org/jcb/article/...

If you’re interested in exploring the relationship between chromatin organization and epigenetic memory using chromatin tracing microscopy, my group is recruiting a talented PhD student 🥳

Here is NIGMS.

This reflects Jon Lorsch's push away from R01s and toward MIRA awards (R35s). While there are some advantages to the R35 mechanism, there are downsides to "putting all of your eggs in one basket" as some discovered this year.

Having a sense of scale helps to think more rigorously and realistically about biological systems.

It already led to cool discoveries, a pending patent, [the start of] a startup… (doi.org/10.1016/j.celrep.2024.114725; doi.org/10.1126/sciadv.adi1535; patents.google.com/patent/WO2024006993A1)

Despite countless rejected grant applications, tireless efforts of super postdoc (and soon to be faculty) Yuan Ren, in collaboration with Jie Yang from Yongli Zhang’s lab, and many collaborators, made the magic happen!

This work was incepted around the time I started my lab in 2013, inspired by previous work from Yongli Zhang’s lab.

Since our sensors do not use a FRET reporter, they are very small and can be inserted in virtually any protein without disrupting its function. We and collaborators have inserted them in 20+ proteins in fungi, nematodes and mammals, with ~90% success!

Genetically encoded mechano-sensors with versatile readouts and compact size Mechanical forces are critical for virtually all fundamental biological processes, yet quantification of mechanical forces at the molecular scale in vivo remains challenging. Here, we present a new st...

Molecular force measurements in vivo are notoriously difficult. We present a new class of programmable force sensors based on engineered coiled-coils, with modular readouts, including fluorescence and luminescence. doi.org/10.1101/2025...
