Aim: We aimed to evaluate the effectiveness of the application of activated autologous monocytes/macrophages (Mo/Mp) on wound healing in diabetic rats.
Methods: Sixty male SD rats were equally divided into the following: control group (normal, nondiabetic), PBS-treated diabetic group, and tumor necrotic factor alpha (TNF-α) plus interferon-γ (IFN-γ)-stimulated or unstimulated Mo/Mp-treated diabetic group. Full-thickness round wounds (1cm×1cm) were created in the right hind foot of rats and the wounds were treated with PBS or Mo/Mp on day 1 after injury. In the following 14 days, the percentage of wound contraction was measured, histologic examination was performed with hematoxylin and eosin staining, and vascular endothelial growth factor (VEGF) in the wound was evaluated by Western blot analysis.
Results: Diabetic rats exhibited impaired wound healing with delayed angiogenesis and VEGF expression. The early application of TNF-α plus IFN-γ-stimulated autologous Mo/Mp to diabetic wounds significantly improved the delayed wound healing through the stimulation of angiogenesis and re-epithelization, as well as restoring the defect in VEGF expression.
Conclusions: Mo/Mp activated by TNF-α and IFN-γ promotes diabetic wound healing and normalizes the defect in VEGF regulation associated with diabetes-induced skin-repair disorders.

Docetaxel (DTX) is widely utilized in breast cancer treatment. However, cancer cell resistance has limited its anti-tumor efficacy. Some molecules called microRNAs (miRNAs), acting like fine-tuned switches, can influence how breast cancer develops and spreads.

Irinotecan (CPT11) chemotherapy-induced diarrhea affects a substantial cancer population due to -glucuronidase (Gus) converting 10--glucuronyl-7-ethyl-10-hydroxycamptothecin (SN38G) to toxic 7-ethyl-10-hydroxycamptothecin (SN38). Existing interventions primarily address inflammation and Gus enzyme inhibition, neglecting epithelial repair and Gus-expressing bacteria. Herein, we discovered that dehydrodiisoeugenol (DDIE), isolated from nutmeg, alleviates CPT11-induced intestinal mucositis alongside a synergistic antitumor effect with CPT11 by improving weight loss, colon shortening, epithelial barrier dysfunction, goblet cells and intestinal stem cells (ISCs) loss, and wound-healing.

Reactive oxygen species (ROS) play essential roles in both physiological and pathological processes. Under physiological conditions, appropriate amounts of ROS play an important role in signaling and regulation in cells. However, too much ROS can lead to many health problems, including inflammation, cancer, delayed wound healing, neurodegenerative diseases (such as Parkinson's disease and Alzheimer's disease), and autoimmune diseases, and oxidative stress from excess ROS is also one of the most critical factors in the pathogenesis of cardiovascular and metabolic diseases such as atherosclerosis.

Background/aims: Hepatocellular carcinoma (HCC) is a malignant cancer with an increasing incidence worldwide. Although numerous efforts have been made to identify effective therapies for HCC, current strategies have limitations. We present a new approach for targeting L-arginine and argininosuccinate synthetase 1 (ASS1).

Background: Colorectal cancer (CRC) is a prevalent malignancy worldwide, associated with significant morbidity and mortality. Cyclin-dependent kinase 1 (CDK1) plays a crucial role in cell cycle regulation and has been implicated in various cancers. This study aimed to evaluate the prognostic value of CDK1 in CRC and to identify traditional Chinese medicines (TCM) that can target CDK1 as potential treatments for CRC.
