Foxa1 disruption enhances human cell integration in human-mouse interspecies chimeras.

Blastocyst complementation can potentially generate a rodent model with humanized nasopharyngeal epithelium (NE) that supports sustained Epstein-Barr virus (EBV) infection, enabling comprehensive studies of EBV biology in nasopharyngeal carcinoma. However, during this process, the specific gene knockouts required to establish a developmental niche for NE remain unclear. We performed bioinformatics analyses and generated Foxa1 mutant mice to confirm that Foxa1 disruption could potentially create a developmental niche for NE.

Induction treatments with and without addition of one dose anthracycline to all-trans retinoid acid and arsenic in pediatric non-high-risk acute promyelocytic leukemia: study protocol for a randomized controlled trial.

Background: The treatment of all-trans retinoic acid (ATRA) and arsenical agent has revolutionarily improved the prognosis of acute promyelocytic leukemia (APL) both in adults and children. Nevertheless, coagulation disorder and differentiation syndrome (DS) are the main causes of early death in APL patients. Early chemotherapy to reduce leukocytes during induction is an important measure to reduce complications and mortality.

MG132 inhibits proliferation and induces apoptosis of acute lymphoblastic leukemia via Akt/FOXO3a/Bim pathway.

Methods: To investigate the anti-leukemic properties of MG132, MTS assays were employed to assess cell viability, and flow cytometry was used to evaluate apoptosis.

CD39 activities in the treated acupoints contributed to the analgesic mechanism of acupuncture on arthritis rats.

Our previous work had identified that at the acupuncture point (acupoint), acupuncture-induced ATP release was a pivotal event in the initiation of analgesia. We aimed to further elucidate the degradation of ATP by CD39. Acupuncture was administered at Zusanli acupoint on arthritis rats, and pain thresholds of the hindpaws were determined.

Anti-inflammatory effects of Tao Hong Si Wu Tang in mice with lung cancer and chronic obstructive pulmonary disease.

Background: Lung cancer (LC) combined with chronic obstructive pulmonary disease (COPD) is a common combination of comorbidities. Anti-inflammation and modulation of oxidative/antioxidative imbalance may prevent COPD-induced LC, and are also crucial to the treatment of LC combined with COPD. Modern studies have shown that Tao Hong Si Wu Tang (THSW) has vasodilatory, anti-inflammatory, anti-fatigue, anti-shock, immunoregulatory, lipid-reducing, micronutrient-supplementing, and anti-allergy effects.

Transition-Metal-Free Radical Relay Cascade Annulation of Amides: Access to Antitumor Active Benzo[b]azepine and Oxindole Derivatives.

Efficient transition-metal-free synthesis of benzo[b]azepines and oxindoles is achieved via a radical relay cascade strategy employing halogen atom transfer (XAT) for aryl radical generation followed by intramolecular hydrogen atom transfer (HAT). Optimization yielded moderate to substantial yields under visible light irradiation. Preliminary biological assessments revealed promising anti-tumor activity for select compounds.

Cyclic GMP-AMP synthase recognizes the physical features of DNA.

Cyclic GMP-AMP synthase (cGAS) is a major cytosolic DNA sensor that plays a significant role in innate immunity. Upon binding to double stranded DNA (dsDNA), cGAS utilizes GTP and ATP to synthesize the second messenger cyclic GMP-AMP (cGAMP). The cGAMP then binds to the adapter protein stimulator of interferon genes (STING) in the endoplasmic reticulum, resulting in the activation of the transcription factor interferon regulatory factor 3 (IRF3) and subsequent induction of type I interferon.

miR-133a and miR-135a Regulate All-Trans Retinoic Acid-Mediated Differentiation in Pediatric Acute Myeloid Leukemia by Inhibiting CDX2 Translation and Serve as Prognostic Biomarkers.

Acute myeloid leukemia (AML) is a type of blood cancer characterized by excessive growth of immature myeloid cells. Unfortunately, the prognosis of pediatric AML remains unfavorable. It is imperative to further our understanding of the mechanisms underlying leukemogenesis and explore innovative therapeutic approaches to enhance overall disease outcomes for patients with this condition.

Research progress in the treatment of chronic fatigue syndrome through interventions targeting the hypothalamus-pituitary-adrenal axis.

Chronic fatigue syndrome (CFS) causes great harm to individuals and society. Elucidating the pathogenesis of CFS and developing safe and effective treatments are urgently needed. This paper reviews the functional changes in the hypothalamus-pituitary-adrenal (HPA) axis in patients with CFS and the associated neuroendocrine mechanisms.

Subregional thalamic functional connectivity abnormalities and cognitive impairments in first-episode schizophrenia.

Background: Previous studies have documented thalamic functional connectivity (FC) abnormalities in schizophrenia, typically examining the thalamus as a whole. The specific link between subregional thalamic FC and cognitive deficits in first-episode schizophrenia (FES) remains unexplored.

Methods: Using data from resting-state functional magnetic resonance imaging, we compared whole-brain FC with thalamic subregions between patients and HCs, and analyzed FC changes in drug-naïve patients separately.

NTPDase1-ATP-P2Y2Rs axis in the sciatic nerve contributes to acupuncture at "Zusanli" (ST36)-induced analgesia in ankle arthritis rats.

Background: The efficacy of acupuncture at Zusanli (ST36) in alleviating lower-limb pain is widely acknowledged in clinical practice, while its underlying mechanism remains incompletely elucidated. Our previous research had revealed that the prompt analgesia induced by needling-ST36 was accompanied by expression alterations in certain exco-nucleotidases within the sciatic nerve. Building upon this finding, the current work focused on NTPDase1, the primary ecto-nucleotidase in the human body, which converts ATP into AMP.
