ZFPL1 Promotes Colorectal Cancer Progression by Stabilizing ASS1 to Drive the Urea Cycle and M2 Macrophage‐Mediated Metastatic Colonization

Advanced Science, EarlyView.
ScRNA‐seq reveals ZFPL1‐specific enrichment in malignant CRC cells. Mechanistically, ZFPL1 stabilizes ASS1 by blocking K57 ubiquitination, activating urea cycle metabolism to drive progression. ZFPL1 inhibition reprograms the TME by suppressing M2 macrophages polarization and promotion M1 macrophages, thereby inhibiting CRC liver metastasis ...

Ubiquitylation activates a peptidase that promotes cleavage and destabilization of its activating E3 ligases and diverse growth regulatory proteins to limit cell proliferation in Arabidopsis [PDF]

, 2017
The characteristic shapes and sizes of organs are established by cell proliferation patterns and final cell sizes, but the underlying molecular mechanisms coordinating these are poorly understood.

Hypoxia‐Induced circPRELID2 Promotes Gastric Cancer Metastasis by Facilitating ZEB2 Translation via PCBP1 O‐GlcNAcylation

Advanced Science, EarlyView.
Under hypoxia, HIF1A is directly bound to the PRELID2 promoter to increase PRELID2 pre‐mRNA expression, followed by the DYRK1A–SFPQ–SAM68 complex binding to Alu‐containing introns in PRELID2 pre‐mRNA, leading to circPRELID2 circularization. CircPRELID2 interacts with PCBP1 and promotes its cytoplasmic retention.

tRNA‐Derived Fragment tRF‐22 Promotes Immunosuppression by Inhibiting HnRNPAB Ubiquitination in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
tRF‐22 fosters an immunosuppressive and pro‐oncogenic tumor microenvironment in ESCC by stabilizing hnRNPAB against TRIM25‐mediated ubiquitination and enhancing TGFβ2 expression, which increases PMN‐MDSCs infiltration and suppresses CD8+ T cells. Targeting tRF‐22 or blocking TGFβ signalling improves anti‐PD1 response, offering a promising therapeutic ...

SCF E3 Ligase Substrates Switch from CAN-D to Can-ubiquitylate

, 2018
Liu et al. (2018) report a mathematical model predicting how the cellular repertoire of SCF E3 ligases is assembled by “adaptive exchange on demand,” with the limited pool of CUL1 scanning the vast sea of F-box proteins for those with substrates ...

Disruption of NF‐κB‐Mediated Copper Homeostasis Sensitizes Breast Cancer to Cuproptosis

Advanced Science, EarlyView.
This study reveals a feedback mechanism regulating copper homeostasis, in which copper directly interacts with TAK1 to activate NF‐κB signaling, while NF‐κB transcriptionally suppresses copper transporter (CTR1) expression. These findings highlight a promising therapeutic strategy for breast cancer by combining NF‐κB inhibitors with copper chelators or
