One of the possible mechanisms contributing to the intrinsic resistance of cancer stem cells (CSCs) to conventional therapies is the inefficiency of activating the apoptotic machinery. In a recent study by Lang and colleagues, the engineered constitutively active pro-apoptotic protein BikDD, which works by inhibiting multiple Bcl-2 family members, was tested in various preclinical breast cancer models. Delivered to cells via an innovative cancer cell-specific gene-therapy approach, BikDD showed potent activity against CSCs and synergized with lapatinib and paclitaxel treatment. This novel and promising therapy warrants further translation to the clinic.

Comparative Postoperative Complications of Acellular Dermal Matrix and Mesh Use in Prepectoral and Subpectoral One-Stage Direct to Implant Reconstruction: A Retrospective Cohort Study.
Ann Plast Surg

Division of Plastic Surgery, Henry Ford Health, Detroit, MI.
Background: One-stage direct-to-implant (DTI) breast reconstruction is increasingly popular with the use of prepectoral reconstruction leading to increased demand for structural scaffolds. It is vital to determine if differences in safety profiles exist among scaffolds.
Methods: We performed a retrospective cohort study of consecutive patients in our breast cancer center undergoing DTI reconstruction.
Boosting Natural Killer Cells' Immunotherapy with Amoxicillin-Loaded Liposomes.

Natural killer (NK) cell immunotherapy is a significant category in tumor therapy due to its potent tumor-killing and immunomodulatory effects. This research delves into exploring the mechanisms underlying the ability of amoxicillin to boost NK cell cytotoxicity in NK cell immunotherapy. Amoxicillin significantly enhances the cytotoxic activity of NK-92MI cells against MCF-7 cells by triggering the initiation of a cytolytic program in target cell-deficient NK-92MI cells and augmenting the degranulation level of NK-92MI cells in the presence of target cells.

Carrier-free nanomedicines exhibited significant potential in elevating drug efficacy and safety for tumor management, yet their self assembly typically relied on chemical modifications of drugs or the incorporation of surfactants, thereby compromising the drug's inherent pharmacological activity. To address this challenge, we proposed a triethylamine (TEA)-mediated protonation-deprotonation strategy that enabled the adjustable-proportion self assembly of dual drugs without chemical modification, achieving nearly 100% drug loading capacity. Molecular dynamic simulations, supported by experiment evidence, elucidated the underlying self-assembly mechanism.
