Phenotypic screening of existing drugs is a good strategy to discover new drugs. Herein, 33 psychotherapeutic drugs in our drug library were screened by phenotypic screening and penfluridol (PFD) was found to exhibit excellent anti-endometrial cancer (EC) activity both and . Furthermore, the molecular target of PFD was identified as septin7, a tumor suppressor in EC.

Healthy dietary patterns rich in legumes can improve metabolic health, although their additional benefits in conjunction with calorie restriction have not been well-established. We investigated effects of a calorie-restricted, legume-enriched, multicomponent intervention diet compared with a calorie-restricted control diet in 127 Chinese prediabetes participants, living in Singapore. The study was a 16-week, single-blind, parallel-design, randomized controlled trial (n = 63 intervention group (IG), n = 64 control group (CG); mean ± SD age 62.

Purpose To develop and evaluate a deep learning-based prognostic model for predicting survival in locoregionally- advanced nasopharyngeal carcinoma (LA-NPC) using serial MRI before and after induction chemotherapy (IC). Materials and Methods This multicenter retrospective study included 1039 LA-NPC patients (779 male, 260 female, mean age 44 [standard deviation: 11]) diagnosed between April 2009 and December 2015. A radiomics- clinical prognostic model (Model RC) was developed using pre-and post-IC MRI and other clinical factors using graph convolutional neural networks (GCN).

The neurotransmitter gamma-aminobutyric acid (GABA) has been thought to be involved in the development of some types of cancer. Yet, the de novo synthesis of GABA and how it functions in hepatocellular carcinoma (HCC) remain unclear. Here, we report that SLC6A12 acts as a transporter of GABA, and that aldehyde dehydrogenase 9 family member A1 (ALDH9A1), not glutamate decarboxylase 1 (GAD1), generates GABA in human HCC.

Reactive oxygen species (ROS) scavenging is a viable approach to promote corneal epithelium wound healing. This study created a single-component hydrogel (HA Gel) with a novel dual-functionalized hyaluronic acid derivative (HA-GA-PBA) containing gallol and phenylboronic acid (PBA) moieties. Both of these moieties were dual-functional.

Nanoscale aggregates play a key role in the pathogenesis of neurodegenerative disorders such as Alzheimer's and Parkinson's disease. However, quantifying these aggregates in complex biological samples, such as biofluids and postmortem brain tissue, has been challenging due to their low concentration and small size, necessitating the development of methods with high sensitivity and specificity. Here, we have developed ultrasensitive assays utilizing the Quanterix Simoa platform to detect α-synuclein, β-amyloid and tau aggregates, including those with common posttranslational modifications such as truncation of α-synuclein and AT8 phosphorylation of tau aggregates.

Hemophilia is caused by the deficiency of clotting factors due to a single genetic abnormality. Replacement therapies have evolved from plasma-derived to recombinant coagulation factor concentrates but continue to have certain limitations. Monoclonal antibodies are clinical prophylactic treatment options unaffected by inhibitors and have better compliance than coagulation factor concentrates for patients with hemophilia.

Squamous cell carcinomas (SCC) are often preceded by potentially malignant precursor lesions, most of which remain benign. The terminal exhaustion phenotypes of effector T-cells and the accumulation of myeloid-derived suppressor cells (MDSC) have been thoroughly characterized in established SCC. However, it is unclear what precancerous lesions harbor a bona fide high risk for malignant transformation and how precancerous epithelial dysplasia drives the immune system to the point of no return.

Autoimmune uveitis and posterior scleritis are ocular diseases caused by immune dysregulation. Their pathogenesis remains elusive, and delayed diagnosis can exacerbate vision loss. Our study analyzed proteomic profiles of 190 patients with Behcet's disease uveitis, posterior scleritis, and Vogt-Koyanagi-Harada syndrome.

  • Overbiopsy is a significant concern in prostate cancer diagnostics, prompting the development of a new urine tumor DNA algorithm called utLIFE to help avoid unnecessary procedures.
  • In clinical tests with a training group and a validation cohort, the utLIFE-PC model demonstrated high accuracy with an area under the curve (AUC) of 0.967 and 0.929, respectively, along with strong sensitivity and specificity.
  • The model outperforms traditional prostate-specific antigen (PSA) tests and other single-dimensional biomarkers, highlighting its potential to enhance prostate cancer diagnostics and reduce unnecessary biopsies.

Background: Pulmonary hypertension (PH) is associated with endothelial dysfunction. However, the cause of endothelial dysfunction and its impact on PH remain incompletely understood. We aimed to investigate whether the hypoxia-inducible FUNDC1 (FUN14 domain-containing 1)-dependent mitophagy pathway underlies PH pathogenesis and progression.

Editing the +58 region of the BCL11A erythroid enhancer has shown promise in treating β-globin disorders. To address variations in fetal hemoglobin (HbF) response, we investigated editing both +58 and +55 enhancers. Rhesus macaques transplanted with edited hematopoietic stem/progenitor cells (HSPCs) following busulfan conditioning exhibited durable, high-level (∼90%) editing frequencies post transplantation with sustained HbF reactivation over 4 years, without hematological perturbations.

Background: Coronary artery disease (CAD) is a complex, heterogeneous disease with distinct etiological mechanisms. These different etiologies may give rise to multiple subtypes of CAD that could benefit from alternative preventions and treatments. However, so far, there have been no systematic efforts to predict CAD subtypes using clinical and genetic factors.

CD8 T cells exhibit remarkable phenotypic diversity in inflammation and cancer. However, a comprehensive understanding of their clonal landscape and dynamics remains elusive. Here we introduce scAtlasVAE, a deep-learning-based model for the integration of large-scale single-cell RNA sequencing data and cross-atlas comparisons.

  • Tranexamic acid, an antifibrinolytic agent, was tested in a study on patients with intracerebral hemorrhage who had ongoing bleeding (spot signs) to assess its effect on hematoma growth when administered within 4.5 hours of onset.
  • A systematic review and meta-analysis were conducted, evaluating randomized trials comparing tranexamic acid to a placebo, specifically including 162 participants with follow-up imaging.
  • Results showed that tranexamic acid treatment did not significantly reduce hematoma growth compared to placebo, with a slightly lower growth rate in the treatment group, but overall outcomes suggested continued monitoring and assessment of safety was needed.

Article Synopsis
  • A study was conducted to find out the best systolic blood pressure targets for patients over 50 with type 2 diabetes and high cardiovascular risk, comparing intensive treatment (target <120 mm Hg) to standard treatment (target <140 mm Hg) over 5 years.
  • Out of 12,821 patients, the intensive treatment group had a lower average systolic blood pressure after one year (121.6 mm Hg) compared to the standard group (133.2 mm Hg), resulting in significantly fewer major cardiovascular events.
  • Despite the lower overall events in the intensive group, there were more cases of symptomatic hypotension and hyperkalemia, but the rates of serious adverse events were similar in both groups.

  • - Preeclampsia is a pregnancy-related condition with unclear causes, and the protein irisin, linked to exercise, may play a role in its development and the health of the placenta.
  • - Research shows that pregnant individuals with preeclampsia have lower irisin levels, which appear early and correlate with other health indicators like blood pressure and protein levels.
  • - Increasing irisin levels in lab studies improved certain functions of trophoblast cells (which support embryo development), while lower levels led to symptoms similar to preeclampsia in animal models.
