TABLE 2.

Studies reporting combined biological effects of hypomagnetic field and microgravity in mammals.

Studied materials	Experimental treatments	Combined biological effects	Refs
8-week-old male C57BL/6 mice	HMF (<300 nT)-HLU (4 weeks)	Accumulation of iron, bone loss and negative effect on the biomechanical properties of the femur	Yang et al. (2018)
Weighing 260 ± 10 g male SD rats	HMF (<300 nT)-HLU (4 weeks)	Expression of RANKL and serum iron concentration increase	Jia et al. (2014)
6-week-old male C57BL/6 mice	HLU (4 weeks) + HMF (<300 nT, 4 weeks)	Lower bone mineral content, iron accumulation, unbalanced bone remodeling	Xue et al. (2020b)
Weighing 260 ± 10 g male SD rats	HMF (<300 nT)-HLU (4 weeks)	The dielectric properties of the gastrocnemius muscle are smaller than that of both alone	Ding et al. (2014b)
Human bronchial epithelial cells BEAS-2B	HMF (<50 nT, 1 week) + X-rays (2, 4, 6 Gy)	Cell survival increase, less DNA damage and more efficient damage repair	Xue et al. (2020a)
