Trefoil Factor‐3 Is a Hypoxia‐Triggered Pro‐Tumorigenic Factor in Hepatoblastoma

Liver International, Volume 46, Issue 4, April 2026.
ABSTRACT Background & Aims Hepatoblastoma (HB) is the most common malignant liver tumour in children. Despite improved survival in low‐risk disease, outcomes for advanced or relapsed HB remain poor, emphasising the need for new therapeutic targets.

Commitment to Myogenic Differentiation Significantly Aggravates the RNA Phenotype in Myotonic Dystrophy Type 1

Neuropathology and Applied Neurobiology, Volume 52, Issue 2, April 2026.
DM1 myoblasts show mild defects, but RNA toxicity intensifies upon differentiation, where broad gene‐expression changes and escalating MBNL1‐driven splicing defects disrupt muscle‐specific pathways, underscoring a key vulnerability at the transition from myogenic precursor cells to myofibres in patients. ABSTRACT Aims Myotonic dystrophy type 1 (DM1) is

A Case of IDH‐Mutant Astrocytoma Harboring an IDH2 R172_H173delinsSN Variant

Neuropathology, Volume 46, Issue 2, April 2026.
ABSTRACT IDH‐mutant gliomas most commonly harbor the canonical IDH1 p.R132H mutation, followed by less common mutations involving IDH1 p.R132 or IDH2 p.R172 codons. We present a case of a 32‐year‐old male found to have a left temporal brain tumor with regional enhancement on brain MRI, for which he underwent resection.

ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Redox regulation meets metabolism: targeting PRDX2 to prevent hepatocellular carcinoma

Molecular Oncology, Volume 20, Issue 3, Page 584-587, March 2026.
PRDX2 acts as a central redox hub linking metabolic dysfunction‐associated steatohepatitis (MASH) to hepatocellular carcinoma (HCC). In normal hepatocytes, PRDX2 maintains redox balance and metabolic homeostasis under oxidative stress. In contrast, during malignant transformation, PRDX2 promotes oncogenic signaling, stemness, and tumor initiation ...

Endometrial Assembloid Model Reveals Endometrial Gland Development Regulation by Estradiol‐Driven WNT7B Suppression

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study developed a 3D endometrial assembloid model to study how uterine glands form and develop. They discovered key interactions between different cell types and identified WNT7B as a regulator controlled by estradiol‐mediated TGFβ1‐VDR interaction.
