Annexin A1 sustains tumor metabolism and cellular proliferation upon stable loss of HIF1A

Annexin A1 sustains tumor metabolism and cellular proliferation upon stable loss of HIF1A.

Despite the approval of numerous molecular targeted drugs, long-term antiproliferative efficacy is rarely achieved and therapy resistance remains a central obstacle of cancer care. Combined inhibition of multiple cancer-driving pathways promises to improve antiproliferative efficacy. HIF-1 is a driver of gastric cancer and considered to be an attractive target for therapy. We noted that gastric...

Annexin 2A sustains glioblastoma cell dissemination and proliferation

Glioblastoma (GBM) is the most devastating tumor of the brain, characterized by an almost inevitable tendency to recur after intensive treatments and a fatal prognosis. Indeed, despite recent technical improvements in GBM surgery, the complete eradication of cancer cell disseminated outside the tumor mass still remains a crucial issue for glioma patients management. In this context, Annexin 2A ...

Selective Inhibitory Effect of Adenosine A1 Receptor Agonists on the Proliferation of Human Tumor Cell Lines

Background: In this study, the effects of three structural analogues of adenosine upon proliferation of human tumor cells were investigated. Previous research showed a cytotoxic effect of adenosine via A3 receptor and A1 receptor and sometimes this effect was receptor independent. The researches showed a differential cytotoxic effect of adenosine and its A3 agonists on cancerous cells, while ot...

Loss of annexin A1 disrupts normal prostate glandular structure by inducing autocrine IL-6 signaling.

Annexin A1 (ANXA1) expression is commonly reduced in premalignant lesions and prostate cancer, but a causal relationship of ANAX1 loss with carcinogenesis has not been established. ANXA1 levels have been shown to inversely correlate with interleukin 6 (IL-6) expression in other cell types and IL-6 has been suggested to enhance prostate cancer initiation and promotion. To investigate whether los...
