Olutasidenib demonstrates significant clinical activity in mutated IDH1 acute myeloid leukaemia arising from a prior myeloproliferative neoplasm.

Acute myeloid leukaemia (AML) arising from a myeloproliferative neoplasm (MPN) is more aggressive and less responsive to therapies compared to de novo AML. Olutasidenib, an oral small-molecule inhibitor of mutated IDH1 (mIDH1), showed encouraging and durable responses in a phase 1/2 study of adults with post-MPN mIDH1 AML. Patients received olutasidenib 150 mg BID monotherapy or in combination with azacitidine.

Layer-specific anatomical and physiological features of the retina's neurovascular unit.

The neurovascular unit (NVU), comprising vascular, glial, and neural elements, supports the energetic demands of neural computation, but this aspect of the retina's trilaminar vessel network is poorly understood. Only the innermost vessel layer-the superficial vascular plexus (SVP)-is associated with astrocytes, like brain capillaries, whereas radial Müller glia interact with vessels in the other layers. Using serial electron microscopic reconstructions from mouse and primate retina, we find that Müller processes cover capillaries in a tessellating pattern, mirroring the wrapping of brain capillaries by tiled astrocytic endfeet.

ALDH1L2 drives HCC progression through TAM polarization.

Background & Aims: Dysregulation of one-carbon metabolism is considered an early hallmark of mitochondrial dysfunction and cancer metabolism. ALDH1L2 belongs to the aldehyde dehydrogenase family and plays an important role in tumor progression. However, little is known about the precise role and underlying mechanisms of ALDH1L2 in hepatocellular carcinoma (HCC).

NR4A3 inhibits the tumor progression of hepatocellular carcinoma by inducing cell cycle G0/G1 phase arrest and upregulation of CDKN2AIP expression.

Nuclear receptor subfamily 4 group A member 3 (NR4A3) is a member of the orphan nuclear receptor superfamily, and exhibits transcription factor activity by binding to sequence-specific DNA. Considering that the specific mechanism by which NR4A3 regulates gene transcription in HCC (hepatocellular carcinoma) has not yet been elucidated, our study aimed to explore the transcriptional role of NR4A3 in regulating the target gene CDKN2AIP (CDKN2A interacting protein), which will suppress the development of HCC. Our data show that NR4A3 is downregulated in human HCC tissues, and that low expression of NR4A3 is correlated with poor prognosis, indicating that NR4A3 could act as a tumor suppressor gene in HCC.

Stratified analysis of the correlation between wedged hepatic venous pressure and portal venous pressure in patients with portal hypertension.

To evaluate the differences in the agreement between wedged hepatic venous pressure (WHVP) and portal venous pressure (PVP) at different hepatic venous pressure gradient (HVPG) levels to identify specific HVPG thresholds where WHVP can reliably estimate PVP, thus enhancing the accuracy of risk stratification and treatment decision-making for portal hypertension (PHT) patients. A multicenter study of 616 patients with PHT from three centers was stratified into five groups by their HVPG: HVPG < 12 (group A), 12 ≤ HVPG < 16 mmHg (group B), 16 ≤ HVPG < 20 mmHg (group C), 20 ≤ HVPG < 24 mmHg (group D), HVPG ≥ 24 mmHg (group E). Concordance was analyzed using Pearson's correlation coefficient (R), the intraclass correlation coefficient (ICC), and Bland‒Altman analysis in each HVPG stratum.

Senescence-Related LncRNAs: Pioneering Indicators for Ovarian Cancer Outcomes.

Unlabelled: In gynecological oncology, ovarian cancer (OC) remains the most lethal, highlighting its significance in public health. Our research focused on the role of long non-coding RNA (lncRNA) in OC, particularly senescence-related lncRNAs (SnRlncRNAs), crucial for OC prognosis. Utilizing data from the genotype-tissue expression (GTEx) and cancer genome Atlas (TCGA), SnRlncRNAs were discerned and subsequently, a risk signature was sculpted using co-expression and differential expression analyses, Cox regression, and least absolute shrinkage and selection operator (LASSO).

Ferroptosis of select skin epithelial cells initiates and maintains chronic systemic immune-mediated psoriatic disease.

Dysregulations of epithelial-immune interactions frequently culminate in chronic inflammatory diseases of the skin, lungs, kidneys, and gastrointestinal tract. Yet, the intraepithelial processes which initiate and perpetuate inflammation in these organs are poorly understood. Here, by utilizing redox lipidomics we identified ferroptosis-associated peroxidation of polyunsaturated phosphatidylethanolamines in the epithelia of patients with asthma, cystic fibrosis, psoriasis and renal failure.

TENT5A mediates the cancer-inhibiting effects of EGR1 by suppressing the protein stability of RPL35 in hepatocellular carcinoma.

Purpose: Terminal nucleotidyltransferase 5A (TENT5A), recently predicted as a non-canonical poly(A) polymerase, is critically involved in several human disorders including retinitis pigmentosa, cancer and obesity. However, the exact biological role of TENT5A in hepatocellular carcinoma (HCC) has not been elucidated.

Methods: The transcription level of TENT5A and clinical correlation were analyzed using the LIRI-JP cohort, the TCGA-LIHC cohort, and clinical tissue samples of HCC patients in our laboratory.

This study aimed to investigate the role of ITFG2, a protein highly expressed in cardiac tissues, in myocardial ischemic injury and its potential interactions with NEDD4-2. An in vivo myocardial infarction (MI) model was induced in mice via left anterior descending artery ligation, and ITFG2 expression was modulated using adeno-associated virus AAV9 vectors. Echocardiography was used to assess cardiac function, and primary mouse cardiomyocytes were cultured and subjected to hypoxia.

Inhibition of CB1R in the Hypothalamic Paraventricular Nucleus Ameliorates Hypertension Through Wnt/β-Catenin/RAS Pathway.

The hypothalamic paraventricular nucleus (PVN), as an important integrating center, plays a prominent role in the pathogenesis of hypertension, in maintaining the stability of cardiovascular activity through peripheral sympathetic nervous activity and secretion of various humoral factors. Acknowledging that the mechanistic targets of the endocannabinoid type 1 receptor (CB1R) are the key signaling systems involved in the regulation of hypertension, we sought to clarify whether inhibition of CB1R within the PVN ameliorates hypertension through Wnt/β-catenin/RAS pathway. Spontaneously hypertensive rats (SHRs) and Wistar Kyoto rats were randomly assigned to different groups and treated with bilateral PVN injections of AM251 (CB1R antagonist, 10 µg/h) or vehicle (artificial cerebrospinal fluid, aCSF) for four weeks.

Decoding the epitranscriptome: a new frontier for cancer therapy and drug resistance.

As the role of RNA modification in gene expression regulation and human diseases, the "epitranscriptome" has been shown to be an important player in regulating many physiological and pathological processes. Meanwhile, the phenomenon of cancer drug resistance is becoming more and more frequent, especially in the case of cancer chemotherapy resistance. In recent years, research on relationship between post-transcriptional modification and cancer including drug resistance has become a hot topic, especially the methylation of the sixth nitrogen site of RNA adenosine-mA (N6-methyladenosine).
