Forensic Context

A study in humans demonstrated that the mir-30b was downregulated in sepsis patients compared to healthy controls [Li et al. DOI:10.1038/s41598-025-89946-6]. A study in mice and human hematopoietic cells demonstrated that γ-radiation upregulated the mir-30b in serum and cells in a dose-dependent manner, where it directly targeted and inhibited the antiapoptotic factor Mcl-1, promoting apoptosis via the intrinsic pathway [Li et al. DOI:10.1007/s10495-016-1238-1]. In a human study of older monozygotic twins, higher plasma levels of the mir-30b were cross-sectionally associated with decreased functionality in activity of daily living fatigue scores [La Grotta et al. DOI:10.1016/j.mad.2025.112099].
