BUFFALO, NY – August 19, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on August 19, 2025, titled “The SCD1 inhibitor aramchol interacts with regorafenib to kill GI tumor cells in vitro and in vivo.” In this study, led by first authors Laurence Booth and Michael R. Booth, along with corresponding author Paul Dent from Virginia Commonwealth University, researchers investigated how aramchol, a drug originally developed for liver disease, works with the cancer drug regorafenib in gastrointestinal (GI) tumor cells. They found that the combination is effective, especially in tumor cells with a specific genetic variant. The combined approach offers a potential new strategy for treating liver and colon cancers. Gastrointestinal cancers, such as liver and colon cancer, are serious global health challenges. Regorafenib, already approved for cancer treatment, can have limited impact and frequently causes side effects. Aramchol, a drug developed to treat fatty liver disease, affects how cancer cells process fats and energy. In this study, researchers tested whether combining these two drugs could improve GI cancer treatment, both in cells and mouse models. The results showed that the drug combination killed liver and colorectal cancer cells more effectively than either drug alone. In animal models, mice with human liver tumors had slower tumor growth, without showing signs of weight loss or other toxicity. The researchers also found that aramchol and regorafenib work together to block important survival pathways inside cancer cells. This combination was especially effective in cells with a genetic variant called ATG16L1 T300, which is more common in people of African ancestry. The treatment triggered stress responses in the cancer cells and disrupted key proteins required for survival. It also activated autophagy, a natural recycling process that clears out damaged parts, eventually leading to cancer cell death. “Aramchol interacted with the multi-kinase inhibitors sorafenib, regorafenib or lenvatinib, to kill GI tumor cells, with regorafenib exhibiting the greatest effect.” Aramchol is currently in clinical trials for fatty liver disease and has a well-established safety profile, while regorafenib is already FDA-approved for cancer treatment. Together, their combination could advance fast into clinical testing for patients with GI cancers. However, researchers note that additional studies are needed to support the launch of early-phase clinical trials. Altogether, this study may offer a more effective and less toxic alternative to current treatments for GI cancers. It also highlights the role of genetic variants in shaping treatment response, suggesting that future therapies could be more precisely tailored to each patient’s unique genetic profile.

BUFFALO, NY - August 13, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on July 29, 2025, titled “PCAIs stimulate MAPK, PI3K/AKT pathways and ROS-Mediated apoptosis in aromatase inhibitor-resistant breast cancer cells while disrupting actin filaments and focal adhesion.” In this study, led by first author Jassy Mary S. Lazarte and corresponding author Nazarius S. Lamango from Florida A&M University College of Pharmacy and Pharmaceutical Sciences, researchers investigated a new class of compounds called polyisoprenylated cysteinyl amide inhibitors (PCAIs) as a potential treatment for aromatase inhibitor (AI) therapy resistant breast cancer. Aromatase inhibitors are a common treatment for estrogen receptor-positive (ER+) breast cancer, but many patients eventually develop resistance, leaving fewer therapeutic options. The study focused on a PCAI compound called NSL-YHJ-2-27, which was tested in long-term letrozole-treated breast cancer cells (LTLT-Ca), an experimental model of AI therapy resistance. NSL-YHJ-2-27 activated two major signaling pathways, MAPK and PI3K/AKT. Although these pathways typically support cancer cell survival, their overstimulation by PCAIs led to increased oxidative stress, damaging the cells and inducing cell death by apoptosis. The compound also reduced levels of RAC1 and CDC42, proteins involved in maintaining cell shape and movement. These alterations resulted in cytoskeletal disruption and reduced structural integrity, making the cancer cells more vulnerable and less capable of spreading. Importantly, the effects of NSL-YHJ-2-27 persisted after the compound was removed, suggesting long-term control over AI resistant cancer cells may be possible. “PCAIs inhibited cell proliferation and colony formation by 95% and 74%, respectively, increased active caspase 7 and BAX 1.5-fold and 56%, respectively. NSL-YHJ-2-27 (10 μM) induced LTLT-Ca spheroid degeneration by 61%.” As a new class of targeted molecules, PCAIs represent an innovative approach distinct from traditional endocrine therapies. Their ability to affect multiple cellular mechanisms simultaneously makes them promising candidates for future drug development. Overall, this study presents a promising new approach for treating AI therapy-resistant breast cancer. By targeting cellular pathways that support survival and mobility, PCAIs like NSL-YHJ-2-27 could provide a novel strategy to manage advanced or resistant forms of the disease. Further research, including in vivo studies and clinical trials, will be essential to confirm these findings and evaluate their therapeutic potential.

Lung cancer, particularly non-small cell lung cancer (NSCLC), is the deadliest cancer worldwide. Cigarette smoking is one of the main causes, but not every smoker develops the disease. This suggests that other biological factors help determine who develops cancer. Researchers from the Division of Pulmonary, Critical Care, Sleep and Occupational Medicine, Indianapolis, and from the Richard L. Roudebush Veterans Affairs Medical Center have now found that cigarette smoke, combined with a weakened DNA repair system, can trigger the early stages of lung cancer, particularly NSCLC. This work, led by first author Nawar Al Nasralla and corresponding author Catherine R. Sears, was recently published in Volume 16 of Oncotarget.

BUFFALO, NY – August 11, 2025 – A new #researchpaper was #published in Volume 16 of Oncotarget on July 25, 2025, titled “Dissecting the functional differences and clinical features of R-spondin family members in metastatic prostate cancer.” In this study, researchers led by first author Aiden Deacon and corresponding author Justin Hwang from the University of Minnesota-Twin Cities investigated a group of genes known as the R-spondin family (RSPO1/2/3/4) in advanced prostate cancer (PC). The RSPO gene family regulates Wnt signaling, a pathway involved in cancer progression. Prostate cancer is the most common cancer among men in the United States and becomes especially dangerous when it spreads beyond the prostate. Most patients are treated with hormone therapies that target the androgen receptor; however, many tumors eventually become resistant. The research team analyzed thousands of tumor samples and found that RSPO2 alterations were more common than changes in other R-spondin genes or even some well-known cancer-related genes like CTNNB1 and APC. RSPO2 amplification occurred in over 20% of metastatic prostate cancer. Patients with these alterations showed signs of more aggressive disease, including higher mutation rates and greater tumor complexity. Using laboratory models, the team discovered that RSPO2 increases cancer cell growth and triggers a biological process called epithelial-mesenchymal transition (EMT). EMT is known to promote tumor spread and resistance to standard treatments. Unlike other genes in the same pathway, RSPO2 also appeared to reduce the activity of androgen receptor genes, suggesting it drives a type of prostate cancer that no longer relies on hormones for growth. “In cell lines, RSPO2 overexpression caused up-regulation of EMT pathways, including EMT-regulatory transcription factors ZEB1, ZEB2, and TWIST1.” Importantly, RSPO2 showed structural differences from other R-spondin proteins, which may allow researchers to design drugs that specifically block its activity. Current therapies targeting the Wnt pathway are limited, and there are no approved drugs that inhibit RSPO2. However, this study highlights RSPO2 as a promising therapeutic target, especially for patients who do not respond to existing hormone-based treatments. This research adds critical knowledge about how aggressive prostate cancers develop and persist despite therapy. The identification of RSPO2 as a key driver of disease progression opens new possibilities for treatment strategies aimed at improving outcomes for patients with advanced prostate cancer.
