eIF4A inhibitors suppress cell-cycle feedback response and acquired resistance to CDK4/6 inhibition in cancer [PDF]

, 2019
CDK4/6 inhibitors are FDA-approved drugs for estrogen receptor-positive (ER+) breast cancer and are being evaluated to treat other tumor types, including KRAS-mutant non-small cell lung cancer (NSCLC).

HSP90AB1‐Mediated Ubiquitin‐Proteasome Degradation of ITGBL1 Promotes Osteosarcoma Progression by Inhibiting Endoplasmic Reticulum Stress‐Induced Autophagy

Advanced Science, EarlyView.
This study delineates a novel HSP90AB1‐ITGBL1 signaling axis governing osteosarcoma. HSP90AB1 promotes K63‐linked ubiquitination and proteasomal degradation of ITGBL1. Restoring ITGBL1 induces reactive oxygen species‐dependent endoplasmic reticulum stress and pro‐death autophagy, suppressing tumor growth and metastasis.

Regulation of CLC-1 chloride channel biosynthesis by FKBP8 and Hsp90β. [PDF]

, 2016
Mutations in human CLC-1 chloride channel are associated with the skeletal muscle disorder myotonia congenita. The disease-causing mutant A531V manifests enhanced proteasomal degradation of CLC-1.

Activated Platelet–Released Heat Shock Protein 90α Triggers Autophagy‐Dependent Neutrophil Extracellular Trap Formation and Amplifies Sepsis

Advanced Science, EarlyView.
HSP90α is significantly upregulated in platelets from sepsis patients, with its origin from megakaryocyte‐derived trafficking. Furthermore, activated platelets secrete HSP90α into the extracellular space in both free and exosome‐associated forms. Finally, extracellular HSP90α directly engages TLR4 on neutrophils to induce autophagy, leading to NET ...

Discovery of small molecule inhibitors of Leishmania braziliensis Hsp90 chaperone

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Leishmaniasis is a neglected disease caused by the protozoa Leishmania ssp. Environmental differences found by the parasites in the vector and the host are translated into cellular stress, leading to the production of heat shock proteins (Hsp). These are

Single‐Cell Atlas of Subchondral Bone Marrow Lesions Reveals Proteostasis Dysfunction as a Druggable Mechanism for Early Osteoarthritis

Advanced Science, EarlyView.
This study reveals that abnormal mechanical stress downregulates the expression of HSP70 and impairs proteasome function in osteoarthritic bone cells, leading to misfolded collagen I accumulation and ER stress. When intracellular proteostasis capacity is exceeded, USP19 mediates the secretion of misfolded proteins into the extracellular space ...

HSP90 inhibitors stimulate DNAJB4 protein expression through a mechanism involving N6-methyladenosine. [PDF]

, 2019
Small-molecule inhibitors for the 90-kDa heat shock protein (HSP90) have been extensively exploited in preclinical studies for the therapeutic interventions of human diseases accompanied with proteotoxic stress.

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

Advanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Molecular and morphological characterization of Avenae-group cyst nematodes (Heteroderidae) from Greece

Journal of Nematology
Cyst nematodes of the genus Heterodera comprise 87 nominal species of economically important plant parasites, with the Avenae-group one of the largest, consisting of 12 species. Samplings for cyst nematode studies were carried out from multiple locations
