A promising new strategy for treating triple-negative breast cancer
——————
Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer. TNBC is more common in women younger than 40 and tends to become resistant to therapies, evidencing the need for more effective treatment strategies. Research led by Karen Cichowski’s lab in collaboration with several LSP members (including Yilin Xu, Jia-Ren Lin, Peter Sorger, and Sandro Santagata) suggests that combined treatment with AKT and EZH2 inhibitors kills TNBC cells more effectively in in vivo models. This work could provide a promising new therapeutic strategy for treating TNBC.
A Step Toward New Solutions for Inflammatory Pain
Clues may lie in interactions between immune cells and pain-sensing neurons
——————
A new study from Clifford Woolf and Peter Sorger revealed novel, bi-directional communication between pain-sensing neurons and immune cells, with different inflammatory stimuli leading to unique cellular responses. These findings increase our understanding of the complex interactions that control pain and bring us closer to developing more targeted analgesics.

High-plex immunofluorescence imaging and traditional histology of the same tissue section for discovering image-based biomarkers selected for Nature Cancer’s 2023 in Review!
This paper introduced the Orion method, which enables high-plex immunofluorescence and H&E imaging of the same slide. This paper was featured as one of the most exciting advances in primary cancer literature in 2023.
Live Cell Imaging IDs Bad Actors in Cancer and Finds Possible Ways to Defeat Them
——————
New work from LSP investigators Patrick Bhola and Anthony Letai makes it possible to identify which cancer cells are primed for cell death via apoptosis. This work could enable future studies to investigate whether targeting poorly primed cancer cells could improve response to therapeutics.
Celebrating a promising Phase II trial for a rare brain tumor treatment
A NEJM article, “BRAF–MEK Inhibition in Newly Diagnosed Papillary Craniopharyngiomas”, describes a Phase II clinical trial and offers some insight into potential targeted treatments for a rare cancer. Papillary Craniopharyngiomas typically occur in the region of the brain near the pituitary gland and optic nerves. Radiation and surgical treatment are often associated with substantial morbidity related to vision loss, neuroendocrine dysfunction, and memory loss. The study team set out to determine whether treatment BRAF–MEK inhibitor combination vemurafenib would lead to better patient outcomes.
For Dr. Sandro Santagata, this work closes a chapter – in 2013, Santagata co-led a team that identified two unique subtypes of craniopharyngiomas and found that papillary craniopharyngiomas nearly always have BRAF-V600E mutations. This discovery stimulated other efforts to repurpose drugs developed for melanoma, resulting in this Phase II clinical trial, in which 15 of 16 patients had a partial response or better to the BRAF-MEK inhibitor. This result is an ode to the scientific community, demonstrating the power of interdisciplinary research and using past successes to inspire future ones. On LinkedIn, Sandro reflected on how this paper represents not only an important step in treating rare cancers but exemplifies how contributions from clinicians, patients, pathologists, philanthropists, and clinical trial experts can move medicine forward.
