Immune checkpoint inhibitors (ICIs) show limited success in treating pancreatic ductal adenocarcinoma (PDAC), largely due to immune evasion mechanisms, including downregulating expression of major histocompatibility complex class I (MHC-I). Our retrospective analysis demonstrated that smoking - a state of elevated CO exposure - is correlated with increased MHC I expression in pancreatic tumors. Here we tested our hypothesis that introducing exogenous CO augments the anti-cancer effects of immunotherapy.

Atractylenolide I (ATL-I) can interfere with Colorectal cancer (CRC) cell proliferation by changing apoptosis, glucose metabolism and other behaviors, making it an effective drug for inhibiting CRC tumor growth. In this paper, we investigated the interactions between ATL-I and Keratin 7 (KRT7), a CRC-specific marker, to determine the potential pathways by which ATL-I inhibits CRC development. The KRT7 expression level in CRC was predicted online using the GEPIA website and then validated.

AXL: shapers of tumor progression and immunosuppressive microenvironments.

Mol Cancer

January 2025

Department of Respiratory Disease, Daping Hospital, Army Medical University, Chongqing, 400042, China.

As research progresses, our understanding of the tumor microenvironment (TME) has undergone profound changes. The TME evolves with the developmental stages of cancer and the implementation of therapeutic interventions, transitioning from an immune-promoting to an immunosuppressive microenvironment. Consequently, we focus intently on the significant role of the TME in tumor proliferation, metastasis, and the development of drug resistance.

January 2025

Department of Nephrology, the Second Affiliated Hospital of Chongqing Medical University, Chongqing, 400010, China.

The incidence of diabetic kidney disease (DKD) is rising annually. Diabetes leads to structural damage and dysfunction in the kidneys, clinically manifesting as progressive proteinuria and declining renal function, ultimately resulting in end-stage renal disease (ESRD). Recent findings have identified a subset of DKD known as normoalbuminuric diabetic kidney disease (NADKD), characterized by normal urine albumin levels but reduced renal function.

Diabetic wounds often exhibit a chronic non-healing state due to the combined effects of multiple factors, including hyperglycemia, impaired angiogenesis, immune dysfunction, bacterial infection, and excessive oxidative stress. Despite the availability of various therapeutic strategies, effectively managing the complex and prolonged healing process of diabetic infected wounds remains challenging. In this study, we combined the natural antidiabetic drug lipoic acid (LA) with the RADA16-YIGSR (RY) peptide obtained through solid-phase synthesis, utilizing reversible hydrogen bonds and coordination bonds for binding.

Aging is a critical factor in the onset and progression of neurodegenerative diseases and cognitive decline, with aging-related neuroinflammation and cellular senescence being major contributors. In the aging brain, the cerebral vascular endothelium overexpresses vascular cell adhesion molecule 1 (VCAM1), activating microglia and leading to neuroinflammation and cognitive impairment. Quercetin, a natural neuroprotective agent widely used for treating neurodegenerative diseases, their therapeutic efficacy, however, is limited by its poor water solubility and inability to penetrate the blood-brain barrier (BBB).

Sensors (Basel)

December 2024

In Situ Devices Center, School of Integrated Circuits, East China Normal University, Shanghai 200241, China.

The rapid advancement of tactile electronic skin (E-skin) has highlighted the effectiveness of incorporating bionic, force-sensitive microstructures in order to enhance sensing performance. Among these, cilia-like microstructures with high aspect ratios, whose inspiration is mammalian hair and the lateral line system of fish, have attracted significant attention for their unique ability to enable E-skin to detect weak signals, even in extreme conditions. Herein, this review critically examines recent progress in the development of cilia-inspired bionic tactile E-skin, with a focus on columnar, conical and filiform microstructures, as well as their fabrication strategies, including template-based and template-free methods.
