Circulating short-chain and branched short-chain fatty acids and the risk of incident type 2 diabetes: findings from the 4C study.

Life Metab

April 2025

Department of Endocrine and Metabolic Diseases, Shanghai Institute of Endocrine and Metabolic Diseases, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China.

Previous studies suggested that fecal short-chain fatty acids (SCFAs) and branched short-chain fatty acids (BCFAs) are associated with glucose regulation. However, the potential relationship between circulating SCFAs and BCFAs with incident diabetes risk in both men and women remains unidentified in prospective cohort studies. In this study, we examined a panel of nine serum SCFAs and BCFAs in 3414 subjects with incident diabetes, and matched normoglycemic controls from the China Cardiometabolic Disease and Cancer Cohort study.

Regulatory T (Treg) cells are essential for maintaining immune homeostasis by suppressing excessive immune responses. In the context of cancer, however, Tregs promote immune evasion and tumor progression, particularly through their unique adaptations within the tumor microenvironment (TME). Recent research has emphasized how metabolic characteristics shape Treg activation, migration, and immunosuppressive function, revealing the impact of metabolic pathways on Treg fitness in homeostasis and within the TME.

Objective: Early predicting response before neoadjuvant chemotherapy (NAC) is crucial for personalized treatment plans for locally advanced breast cancer patients. We aim to develop a multi-task model using multiscale whole slide images (WSIs) features to predict the response to breast cancer NAC more finely.

Methods: This work collected 1,670 whole slide images for training and validation sets, internal testing sets, external testing sets, and prospective testing sets of the weakly-supervised deep learning-based multi-task model (DLMM) in predicting treatment response and pCR to NAC.

Objective: The expression of programmed death 1 (PD-1) on CD8 T cells is associated with their activation and exhaustion, while CD57 serves as a senescence marker. The impact of PD-1 and CD57CD8 T cells on the prognosis of patients with advanced high-grade serous ovarian cancer (HGSOC) remain unclear.

Methods: We assessed the percentages of PD-1 and CD57CD8 T cells in tumor-infiltrating lymphocytes (TILs, n=85) and tumor ascites lymphocytes (TALs, n=87) using flow cytometry.

Background: The mechanism by which ibrutinib, a Bruton's tyrosine kinase inhibitor, can elevate the risk of arrhythmias is not fully elucidated. In this study, we explored how inhibition of off-target kinases can contribute to this phenomenon.

Methods: We performed a Mendelian randomization analysis to examine the causal associations between genetically proxied inhibition of six putative ibrutinib drug targets (ErbB2/HER2, CSK, JAK3, TEC, BLK, and PLCG2) and the atrial fibrillation (AF) risk, proarrhythmic ECG indices, and cardiometabolic traits and diseases.

Fluorescence-guided Surgery for Hepatocellular Carcinoma: From Clinical Practice to Laboratories.

J Clin Transl Hepatol

March 2025

Department of Hepatobiliary Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Fluorescence navigation is a novel technique for accurately identifying hepatocellular carcinoma (HCC) lesions during hepatectomy, enabling real-time visualization. Indocyanine green-based fluorescence guidance has been commonly used to demarcate HCC lesion boundaries, but it cannot distinguish between benign and malignant liver tumors. This review focused on the clinical applications and limitations of indocyanine green, as well as recent advances in novel fluorescent probes for fluorescence-guided surgery of HCC.

Ningbo Key Laboratory of Biomedical Imaging Probe Materials and Technology, Ningbo Cixi Institute of Biomedical Engineering, Ningbo Institute of Materials Technology and Engineering of Chinese Academy of Sciences, Ningbo, 315300, P. R. China.

Triple-negative breast cancer (TNBC) is highly invasive with a poor prognosis, and chemotherapy remains the clinical treatment of choice. Paclitaxel is a commonly used first-line chemotherapy drug, but its untargeted distribution poses clinical challenges. Inspired by antibody-drug conjugates, we develop a precisely structured framework nucleic acid-programmed aptamer-paclitaxel conjugate (FAPC) with chemically well-defined paclitaxel loading dosing, enabling the regulation of receptor-aptamer affinity to facilitate tumor-targeted chemotherapy.

Tianjin Key Laboratory of Radiation Medicine and Molecular Nuclear Medicine, Institute of Radiation Medicine, Chinese Academy of Medical Sciences and Peking Union Medical College, Tianjin, China.

Cyclin-dependent kinase 19 (CDK19) is a potential target for the diagnosis and treatment of prostate cancer. We have previously studied a series of CDK19-targeted PET tracers, but in-depth drug optimization is needed to improve the physiochemical properties of such large and polar tracers. The albumin strategy has received widespread attention in recent years, and we synthesized Ga-IRM-14a and Ga-IRM-14b based on the strategy.

Purpose: Circular RNA (circRNA) has emerged as a promising RNA therapeutic molecule due to its enhanced stability and prolonged protein expression compared to messenger RNA (mRNA). Using circRNA to construct transient Chimeric Antigen Receptor (CAR)-T cells can mitigate the limitations of conventional viral vector-based CAR-T approaches, such as complex process and long-term side effects.

Methods: The study first reconfirmed the advantageous properties of circRNA, focusing on its stability and protein expression efficiency.

Cancer metastasis is the primary cause of cancer-related death, yet the forces that drive cancer cells through various steps and different routes to distinct target organs/tissues remain elusive. In this study, we applied a barcoding system based single-cell lineage tracing approach to study the metastasis rate and route of breast cancer cells and their interactions with the tumor microenvironment (TME) during metastasis. The results indicate that only a small fraction of cells, accounting for fewer than 3% of total barcodes, can intravasate from the primary site into the blood circulation, whereas more cells disseminate through the lymphatic system to different organs.

March 2025

Department of Urology, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua Medicine, Tsinghua University, No. 168, Litang Road, Changping District, Beijing, 102218, China.

We previously demonstrated that the non-O blood type is associated with a higher risk of aggressive prostate cancer (PCa) than the O blood type. However, the influence of the ABO blood phenotype on the exact risk stratification parameters, especially prostate-specific antigen (PSA), remains unknown. We retrospectively evaluated 426 patients with PCa underwent radical prostatectomy in our centers.
