Calhm6 Governs Macrophage Polarization Through Chp1‐Camk4‐Creb1 Axis and Ectosomal Delivery in Inflammatory Responses

Advanced Science, EarlyView.
Calhm6 drives M2 macrophage polarization via the Chp1‐Camk4‐Creb1 axis, suppressing inflammation through calcium‐dependent ectosomal delivery. Calhm6 deficiency enhances M1 responses, boosting bactericidal activity but exacerbating tissue damage. LPS/IFNγ upregulate Calhm6 via Irf1, while IL‐4/Stat6 inhibits it, balancing immune outcomes.

Dynamic Arginine Methylation of YBX1 Relay Controls Its Phase Separation and Chemoradiotherapy Resistance in Rectal Cancer

Advanced Science, EarlyView.
Protein arginine methyltransferase 3 (PRMT3) induces the arginine methylation of Y‐box binding protein 1 (YBX1), which suppresses phase separation and is imperative for its nuclear translocation. Subsequently, lysine‐specific demethylase 4A demethylates YBX1 to unmask the R247 residue and promote its phase separation, which transcriptionally regulates ...

Metastasis of Rectal Signet Ring Cell Carcinoma to Typical Lipoma: A Rare Presentation of the Tumor-to-Tumor Metastasis Phenomenon

Journal of Investigative Medicine High Impact Case Reports
Rectal signet ring cell carcinoma represents a rare subtype of colorectal adenocarcinoma known for its aggressive biological nature and poor prognosis. Although the co-occurrence of colorectal carcinoma with other tumors has been reported, the uncommon ...

Deacetylation of ACLY Mediates RNA M6A‐Modification of NOXA and Promotes Chemoresistance of Colorectal Cancer

Advanced Science, EarlyView.
This study investigates the deacetylation of ACLY at K978 acts as a novel risk in colorectal cancer chemoresistance. The deacetylation of K978 induces ACLY relocation to the nucleus and promotes its binding to RBM15, a m6A methylation modification “writer”.

Large Friable Rectal Neuroendocrine Tumor Complicated by Hemorrhagic Shock: A Rare Case Report and Review of the Literature

JGH Open
Rectal neuroendocrine tumors (NETs) are rare neoplasms that are usually asymptomatic and diagnosed incidentally. There are limited data on the presentation and management of high‐grade poorly differentiated large friable rectal NETs.

Single Cell and Spatial Transcriptomics Define a Proinflammatory and Profibrotic Niche After Kidney Injury

Advanced Science, EarlyView.
By integrating single‐cell RNA sequencing and spatial transcriptomics, tenascin C (TNC) is unveiled as a central organizer of the proinflammatory and profibrotic niche in kidney fibrosis. TNC promotes macrophage activation through TLR4/NF‐κB signaling, leading to renal inflammation and fibrosis.

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 ...
