Low-Level Laser Therapy Promoted Aggressive Proliferation and Angiogenesis Through Decreasing of Transforming Growth Factor-β1 and Increasing of Akt/Hypoxia Inducible Factor-1α in Anaplastic Thyroid Cancer

Abstract: In conclusion, LLLT led to a decrease in TGF-β1 and increase of p-Akt/HIF-1α which resulted to overproliferation and angiogenesis of anaplastic thyroid carcinoma (ATC). Therefore, we suggest that LLLT can influence cancer aggressiveness associated with TGF-β1 and Akt/HIF-1α cascades in some poorly differentiated head and neck cancers.

“…A total of 15 in vivo studies investigating the safety of PBMT in different animal cancer models were identified (Table 2). 62,63,[71][72][73][74][75][76][77][78][79][80][81][82][83] In a study with a chemically induced OSCC hamster cheek pouch model, PBM (660 nm, 30 mW, 424 mW/cm 2 , 56.4 J/cm 2 , and 133 s, 4 J) led to tumor progression. 76 In contrast, a study with a mouse model of multiple UV-induced skin tumors, full-body PBM (670 nm, twice a day, 5 J/cm 2 for 37 days) did not enhance tumor growth in comparison with sham-treated animals.…”

“…was also frequently seen. [35][36][37][38][39] Furthermore, TGF-GFhas been found to be associated with cisplatin-resistant neoplasms. [40][41][42] As a transforming growth factor, TGF-a has not been thoroughly studied in thyroid carcinoma especially ATC with cisplatin-resistance, remaining a gap field of thyroid carcinoma.…”

“…Although LLLT has been reported to have a suppressive effect on cancer cells 94 97 , studies using rodent models suggest that it might modify cancer cell behavior and actually lead to stimulation of dysplastic cells 98 101 . For example, Rhee et al 102 reported that LLLT increased tumor size in rodents when thyroid cancer cells were directly exposed to photodynamic (laser) therapy. Clearly, additional studies with both LLLT and HILT are needed in patients with cancer.…”
