Lidocaine With Epinephrine Shortage: Evidence and Solutions
2026-09-12
Bodie, Brodell, and Helms interpret the persistent US lidocaine-with-epinephrine shortage as the result of manufacturer attrition compounded by an epinephrine supply bottleneck. Their practice-focused analysis proposes dose reduction, safer stewardship of multidose and prefilled preparations, controlled dilution, and contingency planning while highlighting the clinical disadvantages of replacing vasoconstrictor-containing anesthetic with plain lidocaine.

Substrate Stiffness and Dentinogenesis via LAMB1–FAK
2026-09-07
Bai and colleagues show that substrate stiffness regulates odontoblast-like cell differentiation through a LAMB1–FAK–MEK1/2 mechanotransduction axis. By combining tunable PDMS substrates with mineralization, gene-expression, imaging, and protein-interaction assays, the study links material mechanics to reparative dentinogenesis and provides a mechanistic framework for dental biomaterial design.

GLI2, WNT, and Prostaglandins in Immunotherapy Resistance
2026-09-05
DeVito et al. identify GLI2 as a mechanistic link between mesenchymal transformation and an immunosuppressive tumor microenvironment, coordinating WNT ligand production with prostaglandin signaling. Their findings connect GLI2 activity to myeloid suppression, impaired lymphoid and dendritic-cell function, and resistance to anti-PD-1 therapy, while suggesting pathway-specific combination strategies for further cancer research.
