This review discusses the potential use of miRNAs as biological dosimeters for space radiation, the specific role of miRNAs with regard to radiation and microgravity, and the impact miRNAs have on health risks associated with spaceflight.

Protecting activity of desiccated enzymes. Piszkiewicz S, Gunn KH, Warmuth O, Propst A, Mehta A, Nguyen KH, Kuhlman E, Guseman AJ, Stadmiller SS, Boothby TC, Neher SB, Pielak GJ. Protein Sci. 2019 Mar 13. [Epub ahead of print] (Boothby, NNX15AB44G)

This study extracted cytosolic abundant heat soluble proteins (CAHS) proteins from tardigrades, which synthesize (CAHS) proteins to protect its cellular components during desiccation. The experiment indicated that the proteins protected the test enzymes lactate dehydrogenase and lipoprotein lipase against desiccation-, freezing-, and lyophilization-induced deactivation. Results demonstrate the potential use of CAHS proteins as stabilizing excipients in drug formulations and suggest that other proteins may have similar potential.

This study re-examines bones from mice flown on the STS-41 mission with microcomputed tomography (X-ray) that was unavailable at the time the mission was flown in 1990. Examination of the femoral heads in both spaceflight controls and the recombinant human growth hormone (rhGH) mice treated post-flight indicated that that rhGH was ineffective at treating microgravity-induced cancellous bone loss.

Knee and Hip Joint Cartilage Damage from Combined Spaceflight Hazards of Low-Dose Radiation Less than 1 Gy and Prolonged Hindlimb Unloading. Kwok AT, Moore JE, Rosas S, Kerr BA, Andrews RN, Nguyen CM, Lee J, Furdui CM, Collins BE, Munley MT, Willey JS. Radiation Research. 2019 Mar 29. (Willey, NNX15AB50G)

Ground-based investigation using both (simulated) microgravity exposure, using hind limb unloading (HLU) in combination with irradiation, or irradiation alone to characterize the effects on knee and hip joint cartilage. Study findings demonstrate that both individually and combined, HLU and exposure to spaceflight-relevant radiation doses lead to cartilage degradation of the knee and hip with expression of an arthritic phenotype.

Endocrine Effects of Space Flight. Hammond T.G., Birdsall H.H. In: Pathak Y., Araújo dos Santos M., Zea L. (eds) Handbook of Space Pharmaceuticals. Springer, Cham 2019. (Hammond, NNX12AM93G)

The chapter focuses on the effects of space flight on hormones that are secreted by the kidney, hormones that act on the kidney, and how renal function perturbs hormonal balance. Primary among these are the effects on bone metabolism and cardiac function.
