Action Potential Firing Patterns Regulate Dopamine Release via Voltage-Sensitive Dopamine D2 Autoreceptors in Mouse Striatum In Vivo.

Dopamine (DA) in the striatum is vital for motor and cognitive behaviors. Midbrain dopaminergic neurons generate both tonic and phasic action potential (AP) firing patterns in behavior mice. Besides AP numbers, whether and how different AP firing patterns per se modulate DA release remain largely unknown.

A Prodrug Nanodevice Co-delivering Docetaxel and ROR1 siRNA for Enhanced Triple Negative Breast Cancer Therapy.

Triple-negative breast cancer (TNBC) has been a clinical challenge due to its high recurrence and metastasis rates. Chemotherapy remains the primary treatment for TNBC after surgery ablation, but it lacks targeted specificity and causes side effects in normal tissues. Receptor tyrosine kinase-like orphan receptor 1 (ROR1) is significantly expressed in TNBC cells, and small interference RNA (siRNA) targeting ROR1 can effectively suppress ROR1 gene expression, thereby inhibiting proliferation and metastasis.

Sanguinarine suppresses oral squamous cell carcinoma progression by targeting the PKM2/TFEB aix to inhibit autophagic flux.

Background: Oral squamous cell carcinoma (OSCC) is one of the most common malignancies. However, there is no effective treatment for OSCC.

Purpose: This study aimed to identify a natural compound with significant efficacy against OSCC and elucidate its primary mechanism of action.

Reduce Flap Necrosis After Autologous Breast Reconstruction: A Systematic Review.

Background: Autologous breast reconstruction provides substantial benefits in terms of aesthetics and longevity. However, the risk of flap necrosis poses potential challenges to patients' appearance and psychological well-being, while also escalating health care costs. Consequently, examining the risk factors, assessment techniques, and therapeutic approaches for flap necrosis is critically important.

[Asperosaponin VI alleviates TNBS-induced Crohn's disease-like colitis in mice by reducing intestinal epithelial cell apoptosis via inhibiting the PI3K/AKT/NF-κB signaling pathway].

Objectives: To investigate the effects of asperosaponin VI (AVI) on intestinal epithelial cell apoptosis and intestinal barrier function in a mouse model of Crohn's disease (CD)-like colitis and explore its mechanisms.

Methods: Male C57BL/6 mice with TNBS-induced CD-like colitis were treated with saline or AVI (daily dose 150 mg/kg) by gavage for 6 days. The changes in body weight, colon length, DAI scores, and colon pathologies of the mice were observed, and the expressions of inflammatory factors and tight injunction proteins were detected using ELISA and RT-qPCR.
