This review discusses apoptosis modulators in cancer and their recent developments. Through the combined evolution of medicinal chemistry and molecular biology, innovative inducers of apoptosis and inhibitors of anti-apoptotic regulators have been discovered. Many of these agents are now being tested in early-phase trials in cancer patients. We believe that apoptosis targeting holds promise as a relevant strategy in cancer therapeutics.
Purpose of Review Apoptosis is a major mechanism of cancer cell death. Thus, evasion of apoptosis results in therapy resistance. Here, we review apoptosis modulators in cancer and their recent developments, including MDM2 inhibitors and kinase inhibitors that can induce effective apoptosis. Recent Findings Both extrinsic pathways (external stimuli through cell surface death receptor) and intrinsic pathways (mitochondrial-mediated regulation upon genotoxic stress) regulate the complex process of apoptosis through orchestration of various proteins such as members of the BCL-2 family. Dysregulation within these complex steps can result in evasion of apoptosis. However, via the combined evolution of medicinal chemistry and molecular biology, omics assays have led to innovative inducers of apoptosis and inhibitors of anti-apoptotic regulators. Many of these agents are now being tested in cancer patients in early-phase trials. We believe that despite a sluggish speed of development, apoptosis targeting holds promise as a relevant strategy in cancer therapeutics.

Neoadjuvant Chemotherapy for Metaplastic Breast Cancer: Response Rates, Management, and Outcomes

Waqar Haque, Vivek Verma, Mary R. Schwartz, Bora Lim, Niva Mangalampalli, Edward Brian Butler, Bin S. Teh

Summary: This study confirms that the response rates of metaplastic breast cancer (MBC) to neoadjuvant chemotherapy (NAC) are low, with pathologic complete response (pCR) being relatively infrequent. However, early-stage MBC may have a higher likelihood of achieving pCR.

Rauch, Rosalind P. Candelaria, Lei Huo, Stacy L. Moulder, Jeffrey T. Chang

Summary: This study analyzed the clinical outcomes, survival status, and genomic profiles of patients with metaplastic breast cancer (MpBC) who received neoadjuvant therapy. The results showed that MpBC patients had a lower response rate to the therapy, shorter survival time, and distinct genetic characteristics compared to non-metaplastic triple-negative breast cancer (TNBC) patients. Furthermore, some non-MpTNBC patients exhibited similar gene expression profiles and treatment responses to MpBC.

Medicine before and after David Cox

Pavlos Msaouel, Paula Jimenez-Fonseca, Bora Lim, Alberto Carmona-Bayonas, Giancarlo Agnelli

Summary: From the perspective of practicing clinicians, we recount the legacy of Sir David Roxbee Cox (15 July 1924 - 18 January 2022) and acknowledge his pioneering work in developing the logistic and Cox proportional hazard regression models, which revolutionized the analysis and interpretation of categorical and time-to-event survival outcomes in modern medicine. This legacy serves as an inspiration for those who follow in Sir David Cox's footsteps.

Patel, Jun Zou, Andrew Futreal, Adi Diab, Linghua Wang, Roza Nurieva

Summary: Immune checkpoint inhibitors can cause arthritis as an immune-related adverse event (irAE). Managing arthritis-irAE is difficult because standard treatments for arthritis should not hinder antitumor immunity. This study analyzed blood and synovial fluid samples from 20 patients with arthritis-irAE and found a prominent Th1-CD8(+) T cell axis in both blood and inflamed joints. The clonally expanded CX3CR1(hi) CD8(+) T cells in blood and CXCR3(hi) CD8(+) T cells in synovial fluid had significant TCR repertoire overlap. This research provides insights into the mechanisms, predictive biomarkers, and therapeutic targets for arthritis-irAE.

BET inhibition induces vulnerability to MCL1 targeting through upregulation of fatty acid synthesis pathway in breast cancer

Gonghong Yan, Augustin Luna, Heping Wang, Behnaz Bozorgui, Xubin Li, Maga Sanchez, Zeynep Dereli, Nermin Kahraman, Goknur Kara, Xiaohua Chen, Caishang Zheng, Daniel McGrail, Nidhi Sahni, Yiling Lu, Ozgun Babur, Murat Cokol, Bora Lim, Bulent Ozpolat, Chris Sander, Gordon B. Mills, Anil Korkut

Summary: This study suggests that targeting MCL1 and BET may have therapeutic potential for the treatment of basal-like breast cancers. BET inhibition induces an adaptive response leading to the evasion of apoptosis in breast cancer cells driven by MCL1 protein. The mechanism involves upregulation of lipid synthesis enzymes, which affects cell motility and membrane fluidity, as well as the activation of HER2/EGFR signaling. MCL1 copy-number alterations are associated with the effectiveness of BET and MCL1 co-targeting.

Mitochondrial structure and function adaptation in residual triple negative breast cancer cells surviving chemotherapy treatment

Mokryun L. Baek, Junegoo Lee, Katherine E. Pendleton, Mariah J. Berner, Emily B. Goff, Lin Tan, Sara A. Martinez, Iqbal Mahmud, Tao Wang, Matthew D. Meyer, Bora Lim, James P. Barrish, Weston Porter, Philip L. Lorenzi, Gloria V. Echeverria

Summary: It was found that mitochondrial oxidative phosphorylation (OXPHOS) was elevated in triple negative breast cancer (TNBC) cells surviving neoadjuvant chemotherapy (NACT). DNA-damaging agents increased mitochondrial fusion and OXPHOS, while taxanes decreased these effects. Inhibiting mitochondrial fusion and fission suppressed regrowth of residual tumor cells. These findings offer potential strategies to overcome mitochondrial adaptations in chemoresistant TNBC.

Ultralow-dose binary oncolytic/helper-dependent adenovirus promotes antitumor activity in preclinical and clinical studies

Daniel Wang, Caroline E. Porter, Bora Lim, Amanda Rosewell Shaw, Catherine S. Robertson, Mae L. Woods, Ya Xu, Greyson G. W. Biegert, Daisuke Morita, Tao Wang, Bambi J. Grilley, Helen Heslop, Malcolm K. Brenner, Masataka Suzuki

Summary: We have demonstrated the strong antitumor activity of a binary oncolytic/helper-dependent adenovirus (CAdVEC) that lyses tumor cells, expresses IL-12 and PD-L1 blocking antibody. Following successful preclinical studies, we treated four patients with an ultralow dose of CAdVEC, which resulted in significant tumor control and immune repolarization. The combination of CAdVEC with systemic immune checkpoint antibodies induced sustained antitumor responses.

Litton, Debu Tripathy, Stacy Moulder, Lei Huo

Summary: In this study, clinicopathologic features, including sTILs, Ki-67, PD-L1, and androgen receptor, were evaluated in 408 early-stage TNBC patients. Integrating high Ki-67 (>35%) and high sTILs (≥20%) in a computed response score model predicted a pCR rate of 65%. This model has the potential to refine patient selection for neoadjuvant clinical trials evaluating de-escalation strategies.

Phenotypic Plasticity in Circulating Tumor Cells Is Associated with Poor Response to Therapy in Metastatic Breast Cancer Patients

Summary: Circulating tumor cells (CTCs) are valuable indicators for managing metastatic breast cancer (MBC). Enrichment of CTCs based on size and deformability can capture a wider range of tumor cells, providing a complementary approach to tissue biopsy. A longitudinal study using a microcavity array showed that the shift from epithelial CTCs to those with a mesenchymal expression pattern is associated with worse clinical outcomes.

Summary: This study compared the differences in PTEN expression between pre- and post-treatment tumors in patients with triple-negative breast cancer (TNBC). It also explored the possibility of using next-generation sequencing (NGS) as an alternative to immunohistochemistry (IHC) to identify PTEN loss. The results showed that testing different specimens by IHC may generate different PTEN results in a small proportion of TNBC patients.
