Ankylosing spondylitis (AS) is a chronic inflammatory and autoimmune disease that primarily affects the sacroiliac joints and axial skeleton. While the exact pathogenetic mechanism of AS remains unclear, previous reports have highlighted the involvement of genetic factors, immune responses, and gut microbiota dysregulation in the development of this condition. Short-chain fatty acids (SCFAs), which are microbial fermentation products derived from sugar, protein, and dietary fibers, play a role in maintaining the intestinal barrier function and reducing inflammatory responses.

NOTCH3 Mutation Causes Glymphatic Impairment and Promotes Brain Senescence in CADASIL.

CNS Neurosci Ther

January 2025

Department of Neurology, Mental and Neurological Disease Research Center, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China.

Aims: The aim of this study is to investigate the role of glymphatic function of cerebral autosomal dominant arteriopathy, subcortical infarcts, and leukoencephalopathy (CADASIL), the most common monogenic small vessel disease caused by NOTCH3 mutation, and to explore potential therapeutic strategies to improve glymphatic function.

Methods: We assessed glymphatic influx and efflux function in CADASIL mouse models (Notch3) and correlated these findings with brain atrophy in CADASIL patients. We also investigated the underlying mechanisms of glymphatic impairment, focusing the expression of AQP4 in astrocytic endfeet.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Hypoxia-tropic delivery of nanozymes targeting transferrin receptor 1 for nasopharyngeal carcinoma radiotherapy sensitization.

Nat Commun

January 2025

CAS Engineering Laboratory for Nanozyme, Key Laboratory of Biomacromolecules (CAS), CAS Center for Excellence in Biomacromolecules, Institute of Biophysics, Chinese Academy of Sciences, Beijing, China.

Nasopharyngeal carcinoma (NPC), a malignancy highly prevalent in East and Southeast Asia, is primarily treated with radiotherapy (RT). However, hypoxia-induced radioresistance presents a significant challenge. Nanozymes, nanomaterials with catalase-like activity, have emerged as a promising strategy for radiosensitization by converting elevated hydrogen peroxide in the tumor microenvironment into oxygen.

Fibroblast activation protein peptide-targeted NIR-I/II fluorescence imaging for stable and functional detection of hepatocellular carcinoma.

Eur J Nucl Med Mol Imaging

January 2025

Department of Hepatobiliary Surgery and Liver Transplantation Center, The Fifth Affiliated Hospital of Sun Yat-Sen University, 52 Mei Hua East Road, Zhuhai, 519000, China.

Purpose: Cancer-associated fibroblasts (CAFs) are the primary stromal component of the tumor microenvironment in hepatocellular carcinoma (HCC), affecting tumor progression and post-resection recurrence. Fibroblast activation protein (FAP) is a key biomarker of CAFs. However, there is limited evidence on using FAP as a target in near-infrared (NIR) fluorescence imaging for HCC.

Background: Cisplatin is widely used in clinical practice, but its nephrotoxicity severely limits its use. Previous studies have shown that cisplatin-induced acute kidney injury (AKI) is closely related to mitochondrial damage and that alleviating mitochondrial dysfunction can alleviate cisplatin-induced AKI. Methylcrotonyl‑CoA carboxylase 2 (MCCC2) is mainly located in mitochondria, where it catalyzes the catabolism of leucine and maintains mitochondrial function; however, the role of MCCC2 in cisplatin-induced renal injury has not yet been studied.

Inhalable nanovesicles loaded with a STING agonist enhance CAR-T cell activity against solid tumors in the lung.

Nat Commun

January 2025

Center for Infection and Immunity, Guangdong Engineering Research Center of Molecular Imaging, The Fifth Affiliated Hospital of Sun Yat-sen University, Zhuhai, 519000, Guangdong, China.

Suppression of chimeric antigen receptor-modified T (CAR-T) cells by the immunosuppressive tumor microenvironment remains a major barrier to their efficacy against solid tumors. To address this, we develop an anti-PD-L1-expressing nanovesicle loaded with the STING agonist cGAMP (aPD-L1 NVs@cGAMP) to remodel the tumor microenvironment and thereby enhance CAR-T cell activity. Following pulmonary delivery, the nanovesicles rapidly accumulate in the lung and selectively deliver STING agonists to PD-L1-overexpressing cells via the PD-1/PD-L1 interaction.

The lysine-specific demethylase 5 (KDM5) family, a key post-translational modification of chromatin, can shape tumor immune microenvironment. Here, we performed an extensive clinical and bioinformatic analysis to explore the association between KDM5 mutation and tumor immunity and its impact on the outcomes in pan-cancer immunotherapy. In 2943 patients across 12 tumor types treated with immune checkpoint inhibitors, KDM5-mutant tumors were associated with favorable overall survival (hazard ratio, 0.

BMC Urol

December 2024

Department of Andrology, the Center for Men's Health, Shanghai General Hospital, Urologic Medical Center, Shanghai Jiao Tong University, Shanghai, 200080, China.

Background: Vasoepididymostomy (VE) is an important surgical treatment to achieve natural conception for patients with obstructive azoospermia (OA), and only unilateral VE can be performed under certain conditions, such as OA patients with congenital unilateral absence of the vas deferens (CUAVD) and some acquired OA. There is a lack of relevant reports assessing the clinical outcomes of unilateral VE in OA patients with different causes. This study is aimed to describe the clinical features and evaluate treatments and outcomes of unilateral single-armed VE in OA patients.

Article Synopsis
  • Accurate assessment of pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) is vital for reducing toxic effects in breast cancer patients who don’t respond to treatment.
  • Ultrasound (US) is highlighted as an effective tool for evaluating treatment response due to its affordability and safety, and this study aimed to create a predictive model using US and clinicopathological data.
  • The study identified four key characteristics that predict pCR, achieving high accuracy with an AUC of 0.912, 90.0% sensitivity, and 79.6% specificity, indicating that these factors can significantly aid in treatment planning for breast cancer patients.
