Null mutations for genes encoding a major seed storage protein in pea, vicilin, were sought through screening a fast-neutron mutant population. Deletion mutations at four or five vicilin loci, where all vicilin genes within each locus were deleted, were combined to address the question of how removal or reduction of a major storage protein and potential allergen might impact the final concentration of protein per unit mature seed weight, seed yield and viability. While the concentration of seed protein was not reduced in mature seeds of mutant lines, indicative of a re-balancing of the proteome, notable differences were apparent in the metabolite, proteomic and amino acid profiles of the seeds, as well as in some functional properties.

This study examines the association between early pregnancy maternal blood levels of these metals and adverse pregnancy outcomes, while also addressing the differences between low-risk and high-risk groups based on having a history of preterm birth (PTB). This prospective cohort study recruited parous women during first trimester, categorized into low-risk and high-risk groups.

Dysregulation of TRIB2 has been implicated in promoting tumor growth, metastasis, and therapy resistance, making it a promising target for cancer treatment. In this study, we designed and synthesized a series of TRIB2 PROTAC degraders by conjugating a TRIB2 binder 1 with VHL or CRBN ligands via linkers of varying lengths and compositions.
