Summary
Science Advances research found high blood sugar can help cancer cells evade immune attack by thickening the glycocalyx — a sugar-rich surface layer — when cells also face the stiff physical conditions of tumors.
HSF1 emerged as the key regulator connecting tumor mechanics and glucose metabolism to that protective coating; blocking HSF1 stopped glucose-driven glycocalyx buildup in lab models.
Physiological, human-like culture media revealed the effect more clearly than conventional media, suggesting standard lab conditions may miss important tumor biology tied to nutrients and hyperglycemia.
The findings offer a possible explanation for worse cancer outcomes seen with diabetes and metabolic syndrome, while pointing to HSF1 or glycocalyx assembly as potential ways to boost immunotherapy.
