Since its discovery in 2001, there have been a number of important discoveries and findings that have increased our knowledge about the functioning of hepcidin. Hepcidin, the master iron regulator has been shown to be regulated by a number of physiological stimuli and their associated signaling pathways. This chapter will summarize our current understanding of how these physiological stimuli and downstream signaling molecules are involved in hepcidin modulation and ultimately contribute to the regulation of systemic or local iron homeostasis. The signaling pathways and molecules described here have been shown to primarily affect hepcidin at a transcriptional level, but these transcriptional changes correlate with changes in systemic iron levels as well, supporting the functional effects of hepcidin regulation by these signaling pathways.

Growing evidence suggests that plant compounds are emerging as a tremendous source for slowing the onset and progression of Alzheimer's disease (AD). Ursonic acid (UNA) is a naturally occurring pentacyclic triterpenoid with some hypoglycemic, anticancer, and antiinflammatory activities. However, the pharmacological effects of UNA on AD are still unknown.

Background: Radioresistance is a major challenge in the treatment of patients with colorectal cancer (CRC) and impairs the efficacy of radiotherapy. The PI3K/AKT/mTOR signaling pathway plays a critical role in CRC and contributes to the development of radioresistance. Accordingly, targeting this signaling pathway may be a promising strategy to improve oncotherapy.

Recent empirical investigations reinforce the understanding of a profound interconnection between metabolic functions and Obstructive Sleep Apnea-hypopnea Syndrome (OSAHS). This study identifies distinctive miRNA signatures in OSAHS with Metabolic Syndrome (Mets) patients from healthy subjects, that could serve as diagnostic biomarkers or describe differential molecular mechanisms with potential therapeutic implications. In this study, OSAHS with MetS patients showed significantly higher Apnea Hyponea Index(AHI), but lower oxygen desaturation index(ODI 4/h) and minimum pulse oxygen saturation(SpO).

Protein catalysis and allostery require the atomic-level orchestration and motion of residues and ligand, solvent and protein effector molecules. However, the ability to design protein activity through precise protein-solvent cooperative interactions has not yet been demonstrated. Here we report the design of 14 membrane receptors that catalyse G protein nucleotide exchange through diverse engineered allosteric pathways mediated by cooperative networks of intraprotein, protein-ligand and -solvent molecule interactions.

Acyl-CoA oxidase 1 (ACOX1), a member of the acyl-coenzyme A oxidase family, is considered a crucial regulator whose dysregulation is implicated in the occurrence and progression of various cancers. This study aims to elucidate the impact of ACOX1 in CRC, shedding light on its potential as a therapeutic target. Through analysis of the GEO dataset, it was found that ACOX1 is significantly downregulated in colorectal cancer (CRC), and this lower expression level is associated with a worse prognosis.
