Surgical treatment of brain cancer is limited by the inability of current imaging capabilities such as magnetic resonance imaging (MRI) to detect the entirety of this locally invasive cancer. This results in residual cancer cells remaining following surgery, leading to recurrence and death. We demonstrate that intraoperative Raman spectroscopy can detect invasive cancer cells centimeters beyond pathological T1-contrast-enhanced and T2-weighted MRI signals. This intraoperative optical guide can be used to detect invasive cancer cells and minimize post-surgical cancer burden. The detection of distant invasive cancer cells beyond MRI signal has the potential to increase the effectiveness of surgery and directly lengthen patient survival.

The application of standardized criteria to evaluate treatment efficacy is crucial for guiding therapeutic decisions, assessing prognosis, and interpreting outcomes in treating multiple myeloma (MM). The unique characteristics of MM make its response assessment more complex compared with other malignancies. It primarily depends on serum and urine M protein levels, combined with the number of plasma cells in the bone marrow and comprehensive imaging findings.

Endometrial cancer (EC) is a common gynecological malignancy for which polycystic ovarian syndrome (PCOS) has been identified as a significant risk factor. Quercetin, a widely distributed natural flavonoid, has demonstrated potential therapeutic effects in managing both PCOS and EC. However, the specific molecular targets of quercetin in the context of PCOS comorbid with EC (PCOS-EC) remain poorly defined.

Cyclic nucleotide GMP-AMP (cGAMP) plays a critical role in mediating the innate immune response through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway. Recent studies showed that ATP-binding cassette subfamily C member 1 (ABCC1) is a cGAMP exporter. The exported cGAMP can be imported into uninfected cells to stimulate a STING-mediated innate immune response.

Understanding the impact of senescence on disease is limited by the lack of tools to lineage label senescent cells. In a recent Cell issue, Zhao et al. create mouse models to genetically manipulate and trace p16 cells, identifying contrasting roles for senescent macrophages and endothelial cells (ECs) in liver fibrosis.
