Tobacco smoking (TS) is a known risk factor for oral squamous cell carcinoma (OSCC), with evidence indicating that TS alters the bioactive oral microbiota involved in OSCC development. While black raspberry (BRB) mitigates the TS constituent dibenzo[def,p]chrysene (DBP)-induced OSCC through genetic and epigenetic modifications, the contribution of the microbiome remains poorly understood. In the study starting on page 11, Zhao and colleagues demonstrate that BRB significantly modulates both the oral and gut microbiota in a DBP-induced OSCC mouse model. The relative abundance of Akkermansia muciniphila was reduced after BRB treatment in vivo, though this result contrasted with in vitro findings, suggesting potential hostmicrobe or microbe-microbe interactions. Furthermore, BRB but not DBP affected the growth kinetics of human gut microbes in vitro, including lactic acid bacteria and Bacteroides spp. This work extends our knowledge of the protective effect of BRB on DBP-induced OSCC by exploring the microbial dimension. The cover image is adapted from Figure 3C, which presents taxonomic barplots depicting the relative abundance of bacterial families across the four treatment groups. - PDF Icon PDF LinkTable of Contents

Black Raspberry Modulates Cecal and Oral Microbiomes at the Early Stage of a Dibenzo[def,p]chrysene-Induced Murine Oral Cancer Model
Our work clearly demonstrates the modulatory impact of BRB on both gut and oral microbiomes within a DBP-induced OSCC mouse model and paves the way for future research examining a causal role of BRB–microbiota interactions at different stages of disease progression.
Automated Breast Density Assessment for Full-Field Digital Mammography and Digital Breast Tomosynthesis
The proposed model can reduce interobserver variability in BI-RADS density assessment, thereby providing more standard and consistent density assessment for use in decisions about supplemental screening and risk assessment.
Phase II Clinical Chemoprevention Trial of Weekly Erlotinib before Bladder Cancer Surgery
We evaluated the potential of erlotinib in preventing cancer by performing a randomized, double-blind, placebo-controlled trial of weekly erlotinib therapy in participants undergoing surgical removal of suspected noninvasive bladder neoplasia. Weekly erlotinib therapy was tolerated with common grade 1 to 2 toxicities but without evidence of beneficial effect upon urothelial tissue.
What Is the Cost: Financial Toxicity and Screening Fatigue in Li–Fraumeni Syndrome
Li–Fraumeni syndrome (LFS) essentially guarantees a cancer diagnosis in an affected individual’s lifetime. Findings of this study reveal a difficulty for patients with LFS to adhere to recommended rigorous surveillance protocols and question how identified barriers can be broken down to reduce the morbidity and mortality of LFS.
