We are excited to celebrate the publication of our 100th paper. This milestone reflects the creativity, dedication, and collaboration of many outstanding colleagues, students, and trainees over the years. I am deeply grateful to all the collaborators, mentors, supporters, and reviewers who have made this journey possible.

We are grateful to the Yale Cancer Center for the 2026 Class of ’61 Cancer Research Award! We look forward to advancing quantitative proteomics and spatial omics to study proteostasis and uncover new vulnerabilities in cancer and other complex diseases!

How aneuploid cells tolerate chromosome arm gains or losses remains an open question. Using an isogenic human lung cell model with either chromosome 3p loss or 3q gain, combined with quantitative mass spectrometry and isotopic labeling, we reveal distinct proteostasis mechanisms for gain- and loss-type aneuploidy. Surprisingly, while compensation for 3q gain is primarily driven by increased degradation of excess protein complex subunits, 3p loss is neither counteracted by global protein...
