Although Rho GTPases RhoA, RhoB, and RhoC share more than 85% amino acid sequence identity, they play very distinct roles in tumor progression. RhoA and RhoC have been suggested in many studies to contribute positively to tumor development, but the role of RhoB in cancer remains elusive. RhoB contains a unique C-terminal region that undergoes specific post-translational modifications affecting its localization and function. In contrast to RhoA and RhoC, RhoB not only localizes at the plasma membrane, but also on endosomes, multivesicular bodies and has even been identified in the nucleus. These unique features are what contribute to the diversity and potentially opposing functions of RhoB in the tumor microenvironment. Here, we discuss the dualistic role that RhoB plays as both an oncogene and tumor suppressor in the context of cancer development and progression.

Extracellular Matrix-Bound FGF2 Mediates Estrogen Receptor Signaling and Therapeutic Response in Breast Cancer

Josh W. DiGiacomo, Ines Godet, Michael Trautmann-Rodriguez, Daniele M. Gilkes

Summary: Studies have shown that the ECM can play a crucial role in driving ER signaling and resistance to endocrine therapy in breast cancer. By inhibiting FGF2-FGFR1 binding, the sensitivity to ER-targeted therapy can be restored.

Hypoxia-inducible factor-dependent ADAM12 expression mediates breast cancer invasion and metastasis

Ru Wang, Ines Godet, Yongkang Yang, Shaima Salman, Haiquan Lu, Yajing Lyu, Qiaozhu Zuo, Yufeng Wang, Yayun Zhu, Chelsey Chen, Jianjun He, Daniele M. Gilkes, Gregg L. Semenza

Summary: This study discovered that HIFs induce the expression of ADAM12, leading to EGFR signaling activation and subsequently promoting breast cancer cell migration, invasion, and metastasis. Inhibition of ADAM12 expression or activity can effectively reduce tumor cell migration, invasion, and lung metastasis.

A common goal to CARE: Cancer Advocates, Researchers, and Clinicians Explore current treatments and clinical trials for breast cancer brain metastases

Natalie S. Joe, Christine Hodgdon, Lianne Kraemer, Kristin J. Redmond, Vered Stearns, Daniele M. Gilkes

Summary: Breast cancer is the most commonly diagnosed cancer in women worldwide, with a small proportion developing brain metastases and facing a lower survival rate. The challenges lie in developing new approaches to treat, monitor, and prevent breast cancer brain metastasis. Current management includes diagnosis, treatment, and monitoring, along with ongoing translational research focusing on improving survival outcomes and quality of life for patients.

A persistent invasive phenotype in post-hypoxic tumor cells is revealed by fate mapping and computational modeling

Summary: Hypoxia plays a critical role in solid tumor progression and aggressiveness. A new hypoxia fate mapping system allows for the tracking of post-hypoxic cells within tumors. Computational modeling was used to investigate the motility and phenotypic persistence of hypoxic and post-hypoxic cells during tumor progression.

Post-Hypoxic Cells Promote Metastatic Recurrence after Chemotherapy Treatment in TNBC

Ines Godet, Mahelet Mamo, Andrea Thurnheer, D. Marc Rosen, Daniele M. Gilkes

Summary: Intratumoral hypoxia in breast cancer leads to metastasis and chemotherapy resistance. Cells exposed to hypoxia in the primary tumor show decreased sensitivity to doxorubicin and paclitaxel, along with enrichment in cancer stem cell-related pathways. These post-hypoxic cells contribute to resistance and metastatic recurrence.

Detection of Hypoxia in Cancer Models: Significance, Challenges, and Advances

Ines Godet, Steven Doctorman, Fan Wu, Daniele M. Gilkes

Summary: The rapid proliferation of cancer cells and hypoxia cause regions of nutrient and oxygen deprivation in solid tumors. Some cancer cells can adapt to hypoxic conditions and promote cancer progression. Hypoxia is associated with worse patient prognosis, highlighting the need for methods to measure oxygen concentrations. This review provides an overview of the main methods utilized to detect hypoxia in cancer cells.

The Rate of Cisplatin Dosing Affects the Resistance and Metastatic Potential of Triple Negative Breast Cancer Cells, Independent of Hypoxia

Omkar Bhatavdekar, Ines Godet, Daniele Gilkes, Stavroula Sofou

Summary: Understanding the effects of chemotherapy delivery on different hypoxic cell sub-populations is important for controlling tumor growth and metastasis in triple negative breast cancer. In this study, multicellular spheroids were used to evaluate the effects of cisplatin exposure rate and pattern on cell viability and motility. It was found that cell resistance to cisplatin increased with exposure to hypoxia, but not acidosis. Increasing the exposure rate of cisplatin in spheroids enhanced chemotherapy sensitivity and reduced metastatic potential, even in hypoxic cells. This effect was achieved using nanocarriers that quickly released cisplatin and deeply penetrated the spheroid interstitium.

Mebendazole Treatment Disrupts the Transcriptional Activity of Hypoxia-Inducible Factors 1 and 2 in Breast Cancer Cells

Natalie S. Joe, Yuanfeng Wang, Harsh H. Oza, Ines Godet, Nubaira Milki, Gregory J. Riggins, Daniele M. Gilkes

Summary: Mebendazole (MBZ), an FDA-approved anthelmintic, has shown efficacy in reducing solid tumor growth and inhibiting metastasis in preclinical cancer models. This study reveals that MBZ can inhibit the transcriptional activity of HIFs in breast cancer cells and mouse models, thereby blocking the hypoxia response and potentially serving as a therapy for breast cancer.
