Subcellular localization of dihydropyrimidine dehydrogenase

, 1997
Although dihydropyrimidine dehydrogenase (DPD) has been purified and characterized from liver tissues of various mammals conflicting data exist on its subcellular localization.

Molecular Glue cc‐885 Inhibits VHL‐Deficient Clear Cell Renal Cell Carcinoma via ETS1 Degradation

Advanced Science, EarlyView.
VHL‐deficient kidney cancer lacks effective treatments. This study reveals that the molecular glue degrader cc‐885 hijacks the cellular recycling system to selectively destroy the oncogenic protein ETS1, effectively killing VHL‐mutant tumors. Combining CC‐885 with the approved drug belzutifan achieves powerful synergy, offering a promising new ...

Preparation of representative samples of subcellular fractions for electron microscopy by filtration with dextran.

, 1983
A simple method is described for obtaining a representative field of subcellular fractions for thin section electron microscopy. The prefixed sample is admixed together with high molecular weight dextran, filtered onto a Millipore filter, and embedded ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

HNRNPD Induces Radioresistance in Nasopharyngeal Carcinoma by Sequestering GRAMD4 mRNA in Stress Granules

Advanced Science, EarlyView.
HNRNPD promotes radioresistance in nasopharyngeal carcinoma by enhancing stress granule assembly and sequestering GRAMD4 mRNA. This suppresses GRAMD4 translation and inhibits mitochondrial apoptosis. Targeting the integrated stress response with ISRIB restores GRAMD4 expression and sensitizes tumors to radiotherapy, revealing a translational control ...

Cuproptosis and Mitophagy Mediated by the THUMPD1/IGF2R‐Dependent Suppression of AKT and Activation of AMPK Signaling Suppress Lung Adenocarcinoma Progression

Advanced Science, EarlyView.
THUMPD1 drives a tumor‐suppressive signaling cascade in lung adenocarcinoma by promoting IGF2R expression. IGF2R associates with PPP2R1A to suppress AKT and activate AMPK, leading to SLC31A1 upregulation and copper accumulation. Elevated copper disrupts mitochondrial metabolism and induces excessive mitophagy, thereby restraining tumor growth and ...

Oxygen tolerance in neonatal rats: role of subcellular superoxide generation

, 1989
We compared the superoxide anion generating capacity of subcellular fractions from the lungs of neonatal and adult rats. Microsomal and mitochondrial fractions from adult rats produced approximately three times more superoxide (nanomoles per minute per ...

Aggregatory behaviour of platelets incubated with subcellular fractions of normal and chagasic human syncytiotrophoblast

, 1993
A superficie do sinciciotrofoblasto humano não induz agregação das plaquetas maternas apesar de não ser um endotélio. Lesões endoteliais propiciam o aparecimento de agregados plaquetários, o que nos leva a questionar se os componentes subcelulares do ...
