p62/SQSTM1 droplets initiate autophagosome biogenesis and oxidative stress control
Selective autophagy contributes to the degradation of condensates, such as sequestosome 1-bodies, also called p62/SQSTM1-bodies. We showed that endogenous p62 forms gel-like structures, which serve as platforms for autophagosome formation and nuclear ...

Bcl-2-dependent upregulation of autophagy by sequestosome 1/p62 in vitro. [PDF]
To investigate whether sequestosome 1/p62 (p62), a key cargo adaptor protein involved in both the ubiquitin-proteasome system and the autophagy-lysosome system, could directly regulate autophagy in vitro.HEK 293 cells or HeLa cells were transfected with p62-expressing plasmids or siRNA targeting p62.

Accumulation of Ubiquitin and Sequestosome-1 Implicate Protein Damage in Diacetyl-Induced Cytotoxicity. [PDF]
Inhaled diacetyl vapors are associated with flavorings-related lung disease, a potentially fatal airway disease. The reactive α-dicarbonyl group in diacetyl causes protein damage in vitro. Dicarbonyl/l-xylulose reductase (DCXR) metabolizes diacetyl into acetoin, which lacks this α-dicarbonyl group.

Chemotherapeutic sensitization of leptomycin B resistant lung cancer cells by pretreatment with doxorubicin. [PDF]
The development of novel targeted therapies has become an important research focus for lung cancer treatment. Our previous study has shown leptomycin B (LMB) significantly inhibited proliferation of lung cancer cells; however, p53 wild type lung cancer ...

Clinical and Cellular Phenotypes Associated With Sequestosome 1 (SQSTM1) Mutations [PDF]
Abstract Familial Paget's disease of bone has been shown to be associated with mutations in the ubiquitin-associated (UBA) domain of the sequestosome 1 (SQSTM1) gene. We have clinical findings on five families with diverse racial and ethnic backgrounds who all harbor SQSTM1 UBA domain mutations (P387L, P392L, D391fsX394, P392fsX394 ...

p62/Sequestosome-1 Associates with and Sustains the Expression of Retroviral Restriction Factor TRIM5α [PDF]
ABSTRACT TRIM5 proteins mediate a potent block to the cross-species transmission of retroviruses, the most well known being the TRIM5α protein from rhesus macaques, which potently inhibits human immunodeficiency virus type 1 (HIV-1) infection. This restriction occurs at an early stage in the replication cycle and is mediated by the binding of

Tumorigenesis in tuberous sclerosis complex is autophagy and p62/sequestosome 1 (SQSTM1)-dependent [PDF]
Tuberous sclerosis complex (TSC) is a tumor suppressor syndrome characterized by benign tumors in multiple organs, including the brain and kidney. TSC-associated tumors exhibit hyperactivation of mammalian target of rapamycin complex 1 (mTORC1), a direct inhibitor of autophagy. Autophagy can either promote or inhibit tumorigenesis,
