PSMA PET
PSMA PET is a nuclear medicine imaging method that detects and stages prostate cancer using radiotracers binding prostate-specific membrane antigen, standard of care since 2020.
PSMA6
PSMA6 (proteasome 20S subunit alpha 6, alpha-1/IOTA) is a human gene at 14q13.2 encoding a 246-aa alpha-ring subunit of the 20S proteasome; linked to CAD risk variant rs1048990 and proposed as a lung cancer target. Not the prostate PSMA antigen.
PSMB1
PSMB1 encodes beta-6, a non-catalytic structural subunit of the human 20S proteasome core. Biallelic Tyr103His variants cause recessive microcephaly and intellectual disability; high expression marks unfavorable prognosis in breast, liver, lung, and urothelial cancers.
PSMB10
PSMB10 (MECL-1, LMP10, beta2i) encodes the IFN-gamma-inducible trypsin-like catalytic subunit of the immunoproteasome at 16q22.1, replacing constitutive beta2 and supporting MHC class I antigen presentation.
PSMB2
PSMB2 (proteasome 20S subunit beta 2) encodes a non-catalytic beta subunit of the human 20S proteasome core, 201 amino acids, mapped to 1p34.2, incorporated early during proteasome assembly and used for FLAG-tag proteasome purification.
PSMB4
PSMB4 (proteasome 20S subunit beta 4, HsN3/PROS-26) is a human gene at 1q21.3 encoding the non-catalytic β7 subunit of the 20S proteasome, rate-limiting for assembly; biallelic mutations cause PRAAS3/CANDLE autoinflammation.
PSMB8
PSMB8 (LMP7, β5i) is a human chromosome 6 gene encoding the inducible immunoproteasome subunit beta 8; autosomal recessive mutations cause PRAAS, including Nakajo-Nishimura, JMP, and CANDLE syndromes.
PSMB9
PSMB9 (LMP2, β1i) is the human gene for an immunoproteasome catalytic subunit at 6p21.3 in the MHC class II region; IFN-γ-induced, it replaces β1 to generate hydrophobic C-terminal peptides for MHC class I presentation, with SNPs linked to multiple sclerosis risk and a p.G156D variant causing neonatal autoinflammation.
PSMD1
PSMD1 (S1, P112, Rpn2), gene ID 5707 on human chromosome 2, encodes the largest non-ATPase lid subunit of the 19S proteasome regulator; overexpressed in HCC, myeloma, and CML, a prognostic marker and emerging siRNA target.
PSMD14
PSMD14, also called Rpn11 or POH1, is the essential zinc-dependent JAMM metalloprotease deubiquitinase of the 19S proteasome lid that removes whole polyubiquitin chains en bloc, coupling deubiquitination to ATP-dependent substrate degradation, and is an emerging cancer drug target.
PSMD2
PSMD2 (Rpn1, 26S proteasome non-ATPase regulatory subunit 2) is a 19S base scaffold and ubiquitin/UBL-binding subunit of the 26S proteasome, overexpressed in lung, breast, esophageal, bladder, pancreatic, and liver cancers and a candidate therapeutic target.
PSMD4
PSMD4 (Rpn10, S5a) is the 377-aa intrinsic ubiquitin receptor of the 26S proteasome's 19S regulatory particle, with a VWA domain and two UIMs binding K48/K63 polyubiquitin; embryonic lethal in mice and implicated in myeloma and liver cancer.
PSMPD trial
PSMPD trial (NCT05239065), Personalized Stress Management With Application of Portable Devices in Occupational Populations: nonrandomized controlled study in two Wuhan hospitals testing Huawei-device-supported stress coaching for 245 healthcare workers; PSS improved, HRV did not differ.
Psoas major muscle
Psoas major: deep core muscle joining the iliacus as the iliopsoas, the thigh's primary flexor; inserts separately on the lesser trochanter and crosses the ~3 o'clock psoas valley of the acetabular rim.
Psocidae
Psocidae, the common barklice, is the largest family of free-living barklice (Psocodea: Psocomorpha: Psocetae), with over 1,000 species in about 80 genera, mostly tropical, classified in three subfamilies and ten tribes.
Psocodea
Psocodea is an insect order uniting bark lice, book lice, and parasitic lice (former orders Psocoptera and Phthiraptera, now synonyms), with over 11,000 species, seven suborders, and a single origin of parasitism predating the K-Pg boundary.
Psophia
Psophia is a genus of Amazonian ground-dwelling birds known as trumpeters, the only genus of the family Psophiidae in the order Gruiformes, established by Linnaeus in 1758.
Psophocarpus
Psophocarpus, a small African-Madagascan legume genus in Fabaceae tribe Phaseoleae, is known for the winged bean P. tetragonolobus, a protein-rich multipurpose tropical crop with four-winged, explosively dehiscent pods.
