[PMID: 39151679 DOI: 10.1016/j.phrs.2024.107349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 07/31/2024] [Accepted: 07/31/2024] [Indexed: 08/19/2024]
Abstract
In future regenerative medicine, far-infrared radiation (FIR) may be an essential component of optical therapy. Many studies have confirmed or validated the efficacy and safety of FIR in various diseases, benefiting from new insights into FIR mechanisms and the excellent performance of many applications. However, the lack of consensus on the biological effects and therapeutic parameters of FIR limits its practical applications in the clinic. In this review, the definition, characteristics, and underlying principles of the FIR are systematically illustrated. We outline the therapeutic parameters of FIR, including the wavelength range, power density, irradiation time, and distance. In addition, the biological effects, potential molecular mechanisms, and preclinical and clinical applications of FIR are discussed. Furthermore, the future development and applications of FIR are described in this review. By applying optimal therapeutic parameters, FIR can influence various cells, animal models, and patients, eliciting diverse underlying mechanisms and offering therapeutic potential for many diseases. FIR could represent a superior alternative with broad prospects for application in future regenerative medicine.

Amelioration of Motor Performance and Nigrostriatal Dopamine Cell Volume Using a Novel Far-Infrared Ceramic Blanket in an A53T Alpha-Synuclein Transgenic Parkinson's Disease Mouse Model. Curr Issues Mol Biol 2023; 45:9823-9837. [PMID: 38132459 PMCID: PMC10742635 DOI: 10.3390/cimb45120613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 12/23/2023] Open
Abstract
We had attended a Parkinson's Disease (PD) patient for a non-healing wound who reported a marked decrease in his hand tremor and freezing of gait when his wound was exposed to a ceramic far-field infrared (cFIR) blanket. PD is the most frequent motor disorder and the second most frequent neurodegenerative disease after Alzheimer's Disease (AD). The tremor, rigidity, and slowness of movement associated with Parkinson's disease (PD) affect up to 10 million people throughout the world, and the major contributing factor to the pathogenesis of PD is the accumulation and propagation of pathological α-synuclein (α-Syn) and the death of dopaminergic cells in the Nigrostriatal system. Efforts to slow or stop its spreading have resulted in the development and use of dopaminergic drug replacement therapy. Unfortunately, there is a loss of about 70-80% of substantia nigral dopaminergic neurons in patients by the time they are diagnosed with PD, and various dopaminergic drugs provide only temporary relief of their motor symptoms. There are limitations in treating PD with many conventional medications, necessitating a combination of pharmaceutical and non-pharmacological therapy as an essential adjunct to better address the health and welfare of PD patients. We used male adult A53T alpha-synuclein transgenic mice exposed to a ceramic far-infrared blanket. Motor activity was assessed using the rotarod apparatus, and mouse brains were examined to quantify the fluorescence intensities of the immunostained samples. A53T alpha-synuclein transgenic mice had a significantly shorter time stay on the rotating bar than the wild-type mice (B6C3H). The rotarod performance was significantly improved in A53T alpha-synuclein transgenic mice exposed to cFIR as well as B6C3H healthy wild mice exposed to cFIR. There was a significant statistical and substantive increase in the cellular composition of the Striatum and substantia nigra of cFIR-treated mice. Improvement in motor performance is seen in PD mice and wild mice and is associated with increases in cell volume in the substantia nigra and striatum after treatment.

Accelerated Wound Healing Using a Novel Far-Infrared Ceramic Blanket. Life (Basel) 2021; 11:life11090878. [PMID: 34575027 PMCID: PMC8469926 DOI: 10.3390/life11090878] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 08/11/2021] [Accepted: 08/25/2021] [Indexed: 11/16/2022] Open
Abstract
INTRODUCTION Wounds are associated with ranges of simple to complex disruption or damage to anatomical structure and function. They are also associated with enormous economic and social costs, increasing yearly, resulting in a severe impact on the wellbeing of individuals and society. Technology that might accelerate wound healing is associated with many benefits to injured people. METHODS BALBc mice underwent symmetrical excisional wounds through the panniculus carnosus. They were divided into a treatment group placed on an autonomous ceramic far-field infrared blanket (cIFRB) and a control group maintained under standard conditions. We also expanded and cultured adipose tissue-derived mesenchymal stem cells (MSCs) on cIFRB and compared them to standard conditions subjected to a scratch injury to compare survival, proliferation, and wound healing. RESULTS The wound healing of the cIRFB treatment group was significantly faster than the control group of mice. The wound-healing effect of mesenchymal stem cells on cIRFB was also increased and associated with significant migration to the wound area. CONCLUSIONS Wound healing is improved in a mouse model exposed to cFIRB. The ceramic blanket also promotes survival, proliferation, increased migration, and wound healing of MSCs without affecting their survival and proliferation. The utilization of cFIRB in cellular biology and medical applications may be promising in many situations currently explored in animal and human models. This technology needs no direct or battery power source and is entirely autonomous and noninvasive, making its application possible in any environment.

Cho DH, Lee HJ, Lee JY, Park JH, Jo I. Far-infrared irradiation inhibits breast cancer cell proliferation independently of DNA damage through increased nuclear Ca 2+/calmodulin binding modulated-activation of checkpoint kinase 2. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2021; 219:112188. [PMID: 33901880 DOI: 10.1016/j.jphotobiol.2021.112188] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 03/30/2021] [Accepted: 04/06/2021] [Indexed: 12/31/2022]
Abstract
Far-infrared (FIR) irradiation is reported to inhibit cell proliferation in various types of cancer cells; the underlying mechanism, however, remains unclear. We explored the molecular mechanisms using MDA-MB-231 human breast cancer cells. FIR irradiation significantly inhibited cell proliferation and colony formation compared to hyperthermal stimulus, with no alteration in cell viability. No increase in DNA fragmentation or phosphorylation of DNA damage kinases including ataxia-telangiectasia mutated kinase, ataxia telangiectasia and Rad3-related kinase, and DNA-dependent protein kinase indicated no DNA damage. FIR irradiation increased the phosphorylation of checkpoint kinase 2 (Chk2) at Thr68 (p-Chk2-Thr68) but not that of checkpoint kinase 1 at Ser345. Increased nuclear p-Chk2-Thr68 and Ca2+/CaM accumulations were found in FIR-irradiated cells, as observed in confocal microscopic analyses and cell fractionation assays. In silico analysis predicted that Chk2 possesses a Ca2+/calmodulin (CaM) binding motif ahead of its kinase domain. Indeed, Chk2 physically interacted with CaM in the presence of Ca2+, with their binding markedly pronounced in FIR-irradiated cells. Pre-treatment with a Ca2+ chelator significantly reversed FIR irradiation-increased p-Chk2-Thr68 expression. In addition, a CaM antagonist or small interfering RNA-mediated knockdown of the CaM gene expression significantly attenuated FIR irradiation-increased p-Chk2-Thr68 expression. Finally, pre-treatment with a potent Chk2 inhibitor significantly reversed both FIR irradiation-stimulated p-Chk2-Thr68 expression and irradiation-repressed cell proliferation. In conclusion, our results demonstrate that FIR irradiation inhibited breast cancer cell proliferation, independently of DNA damage, by activating the Ca2+/CaM/Chk2 signaling pathway in the nucleus. These results demonstrate a novel Chk2 activation mechanism that functions irrespective of DNA damage.
