Tumour DDR1 promotes collagen fibre alignment to instigate immune exclusion

X Sun, B Wu, HC Chiang, H Deng, X Zhang, W Xiong… - Nature, 2021 - nature.com
Immune exclusion predicts poor patient outcomes in multiple malignancies, including triple-
negative breast cancer (TNBC). The extracellular matrix (ECM) contributes to immune …

[HTML][HTML] RNA polymerase II pausing factor NELF in CD8+ T cells promotes antitumor immunity

B Wu, X Zhang, HC Chiang, H Pan, B Yuan… - Nature …, 2022 - nature.com
Abstract T cell factor 1 (TCF1) is required for memory and stem-like CD8+ T cell functions.

[HTML][HTML] Genetic ablation of adipocyte PD-L1 reduces tumor growth but accentuates obesity-associated inflammation

B Wu, HC Chiang, X Sun, B Yuan, P Mitra… - … for Immunotherapy of …, 2020 - ncbi.nlm.nih.gov
The programmed death-ligand 1 (PD-L1)-dependent immune checkpoint attenuates host
immunity and maintains self-tolerance. Imbalance between protective immunity and …

[HTML][HTML] Myogenic differentiation depends on the interplay of Grb2 and N-WASP

P Mitra, T Thanabalu - Biochimica Et Biophysica Acta (BBA)-Molecular Cell …, 2017 - Elsevier

R-Loop Functions in Brca1-Associated Mammary Tumorigenesis

HC Chiang, L Qi, P Mitra, Y Hu, R Li - bioRxiv, 2024 - biorxiv.org
Excessive R-loops, a DNA-RNA hybrid structure, are associated with genome instability and
BRCA1 mutation-related breast cancer. Yet the causality of R-loops in tumorigenesis …

Understanding the role of immune exclusion in mammary tumor growth

P Mitra, J Azpurua, HC Chiang, R Li - Cancer Research, 2024 - AACR
Multiple solid tumor types, including triple-negative breast cancer (TNBC), respond poorly to
immunotherapy due to low infiltration of CD8+ T cells into the tumor core. The extracellular …
