The arginine-phenylalanine-amide neuropeptide receptor family comprises a subclass within the G protein-coupled receptor superfamily with crucial roles in physiological regulation. These receptors recognize and bind neuropeptides with an arginine-phenylalanine-amide motif, thereby participating in a variety of biological processes such as energy metabolism, pain perception, and reproductive functions. In this review, we explore the physiological and pathological processes involving these receptors and delve into the structure-activity relationships of their ligand peptides, clarifying the key structural motifs within these neuropeptides that determine their biological activity, pharmacological potency, and receptor selectivity.

Abscisic acid (ABA) is a key phytohormone involved in regulating plant growth and responses to environmental stress. As receptors of ABA, pyrabactin resistance 1 (PYR)/PYR1-like (PYL) proteins play a central role in initiating ABA signal transduction. In this study, a total of 30 genes were identified and classified into three sub-families (PYL I-III) in the pan-genome of 17 species, through phylogenetic analysis.

Allosteric modulators have gained substantial interest in current GPCR drug discovery. Here, we present a mechanism of allosteric modulation involving the dimerization of GPR3, a promising drug target for metabolic diseases and central nervous system disorders. We show that GPR3 forms constitutive homodimers in live cells and reveal that the inhibitor AF64394 functions as a negative allosteric modulator (NAM) specifically targeting dimeric GPR3.

PUF proteins (named for Pumilio and mRNA binding factor or FBF) are a family of RNA-binding proteins. FBF is a collective term for two PUF proteins, FBF-1 and FBF-2, that maintain germline stem cells. FBF binds the 3'UTR of target RNAs and together with partner proteins represses translation of mRNAs that promote differentiation.

In the era of the experience economy, the tourist experience has become a key factor in the development of tourist destinations. Unlike traditional sightseeing experiences, tourism cultural experiences allow for engagement in cultural activities at the destination, thereby fostering a deeper emotional connection with the local community, which subsequently influences tourists' citizenship behavior. The "Village Basketball League" in Taijiang County, Guizhou Province is characterized as a form of tourism cultural experience with high integration and strong involvement.

Despite the Prognostic Nutritional Index (PNI) serving as a crucial prognostic marker for predicting survival outcomes in cancer patients, its association with the risk of Colorectal Cancer (CRC) is not well comprehended. We hypothesized that lower PNI levels are associated with a higher risk of CRC. The datasets from the National Health and Nutrition Examination Survey (NHANES) spanning from 2007 to 2016 were employed in this study, incorporating data on demographics, laboratory tests, and questionnaires.
