New insights on extramedullary granulopoiesis and neutrophil heterogeneity in the spleen and its importance in disease.

J Leukoc Biol

November 2024

Immunology Center of Georgia, Augusta University, 1410 Laney Walker Blvd, Augusta, GA 30912, United States.

Neutrophils are traditionally viewed as uncomplicated exterminators that arrive quickly at sites of infection, kill pathogens, and then expire. However, recent studies employing modern transcriptomics coupled with novel imaging modalities have discovered that neutrophils exhibit significant heterogeneity within organs and have complex functional roles ranging from tissue homeostasis to cancer and chronic pathologies. This has revised the view that neutrophils are simplistic butchers, and there has been a resurgent interest in neutrophils.

Article Synopsis
  • Oleanolic acid (OA) and Ursolic acid (UA) are bioactive compounds that show potential anti-cancer effects, particularly at low doses (5-10 µM) against breast cancer cells, despite their low bioavailability from oral intake.
  • Research indicates that OA and UA induce cell death in breast cancer (BrCa) cells primarily through autophagy rather than apoptosis, and this effect can be enhanced by inhibiting specific survival pathways (PI3K/Akt/mTOR).
  • Combining OA and UA with a PI3K inhibitor effectively increases their anti-cancer activity, suggesting this combination warrants further testing in clinical trials for treating breast cancer.

Protein-Based Predictive Biomarkers to Personalize Neoadjuvant Therapy for Bladder Cancer-A Systematic Review of the Current Status.

Int J Mol Sci

September 2024

Department of Biochemistry and Molecular Biology, Medical College of Georgia, Augusta University, 1410 Laney Walker Blvd., Augusta, GA 30912, USA.

The clinical outcome of patients with muscle-invasive bladder cancer (MIBC) is poor despite the approval of neoadjuvant chemotherapy or immunotherapy to improve overall survival after cystectomy. MIBC subtypes, immune, transcriptome, metabolomic signatures, and mutation burden have the potential to predict treatment response but none have been incorporated into clinical practice, as tumor heterogeneity and lineage plasticity influence their efficacy. Using the PRISMA statement, we conducted a systematic review of the literature, involving 135 studies published within the last five years, to identify studies reporting on the prognostic value of protein-based biomarkers for response to neoadjuvant therapy in patients with MIBC.
