This study presents novel findings on the potential of phloretin， an apple polyphenol， to enhance the effectiveness of anti-HER2 antibody therapy in HER2-positive breast cancer patients. Our research reveals that phloretin inhibits type II glucose transporter (GLUT2) activity， significantly reducing cancer cell glucose uptake. We confirmed the overexpression of GLUT1 and GLUT2 mRNA in paired human breast tumor tissues， with GLUT2 overexpression associated explicitly with poorer survival rates in breast cancer patients. Treatment with phloretin was observed to increase the interaction between GLUT2 and HER2 proteins， attenuate glycolysis， and enhance the binding affinity of anti-HER2 antibody drugs to target human breast cancer cells. Furthermore， the efficacy of the combination therapy involving phloretin and antibody drugs was reaffirmed in a cell-derived xenograft (CDX) tumor animal model， particularly in suppressing the growth of Trastuzumab-resistant HER2+ breast cancer. These significant findings suggest that targeting GLUT2 activity with phloretin in combination with anti-HER2 antibody drugs may help mitigate the development of drug-resistant breast cancer， offering valuable insights for enhancing tumor treatment strategies and contributing to developing more effective therapies.

Infectious Spondylitis-Associated Staphylococcus aureus with Virulence Gene pvl or tst Causes More Necrosis than Apoptosis in Human Alveolar Basal Epithelial Cell Line A549

Methicillin-sensitive and resistant Staphylococcus aureus (MSSA and MRSA, respectively) can cause non-tuberculosis infectious spondylitis. In 43 cases of bacterial infectious spondylitis, Mycobacterium tuberculosis and S. aureus were the two major causative pathogens. MRSA caused more anterior operations and thoracic infections, while MSSA caused more posterior infections and lumbar infections. Differences between six S. aureus isolates from infectious spondylitis were characterized. MLST and staphylococcal cassette chromosome mec (SCCmec) analysis identified MSSA ST959 and ST30 isolates, MRSA ST239/SCCmec IIIA isolates 2 and 3, ST59/SCCmec IIIA-like isolate 6, and ST30/SCCmec IV isolate 5. While all of the isolates were resistant to penicillin and ampicillin, the MRSA isolates were more resistant than the MSSA isolates. Carbapenem-resistant MRSA ST239/SCCmec IIIA and ST59/SCCmec IIIA-like isolates of the agr1 type were also resistant to clindamycin and erythromycin. Leukocidin genes (pvl or lukED) and hemolysin genes (hla, hld and hlg) were present in all of the isolates. All six isolates caused more necrosis than apoptosis in the human alveolar basal epithelial cell line A549;however, ST59/SCCmec IIIA-like isolate 6, ST30/ SCCmec IV isolate 5 with pvl genes, and MSSA ST30 isolates with tst caused greater than 40% cell death after the 4-h incubation. Regardless of the MRSA isolate and its SCCmec type or the MSSA isolate, the infectious spondylitis-associated S. aureus isolates differed genetically, and the pvl and tst genes may be important genes for cell necrosis.
