Anticancer effects of OSW-1 on colorectal cancer cells via the ROS/NLRP3/Caspase-1 pyroptosis signaling pathway.

Pyroptosis, a form of programmed cell death, has recently emerged as a compelling molecular mechanism associated with the efficacy of chemotherapeutic drugs in tumor treatment. OSW-1, derived from the bulbs of Ornithogalum saundersiae Baker, exhibits a diverse range of pharmacological effects. However, its specific antitumor effects on colorectal cancer (CRC) and the mechanisms underlying these effects remain elusive.

Insights into the mechanisms, regulation, and therapeutic implications of extracellular matrix stiffness in cancer.

The tumor microenvironment (TME) is critical for cancer initiation, growth, metastasis, and therapeutic resistance. The extracellular matrix (ECM) is a significant tumor component that serves various functions, including mechanical support, TME regulation, and signal molecule generation. The quantity and cross-linking status of ECM components are crucial factors in tumor development, as they determine tissue stiffness and the interaction between stiff TME and cancer cells, resulting in aberrant mechanotransduction, proliferation, migration, invasion, angiogenesis, immune evasion, and treatment resistance.

Sea conch () peptide hydrolysate regulates NF-κB pathway and restores intestinal immune homeostasis in DSS-induced colitis mice.

Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract. Sea conch peptide hydrolysate (CPH) was produced by enzymatic digestion of fresh conch meat with trypsin enzyme. To analyze the molecular composition, functional groups, and structural morphology of the hydrolysate, we employed liquid chromatography-mass spectrometry (LC-MS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM).

Construction and validation of immune-associated lncRNA model for predicting immune status and therapeutic reactions of triple-negative breast cancer.

Objective: The immune status of the tumor microenvironment significantly impacts the clinical prognosis of triple-negative breast cancer (TNBC). The involvement of long noncoding RNAs (lncRNAs) in tumor immune infiltration is widely acknowledged. Therefore, it is crucial to explore the role of significant immune-related lncRNAs in TNBC.

Intricate relationship between cancer stemness, metastasis, and drug resistance.

Cancer stem cells (CSCs) are widely acknowledged as the drivers of tumor initiation, epithelial-mesenchymal transition (EMT) progression, and metastasis. Originating from both hematologic and solid malignancies, CSCs exhibit quiescence, pluripotency, and self-renewal akin to normal stem cells, thus orchestrating tumor heterogeneity and growth. Through a dynamic interplay with the tumor microenvironment (TME) and intricate signaling cascades, CSCs undergo transitions from differentiated cancer cells, culminating in therapy resistance and disease recurrence.

Correlation of glucose and lipid metabolism, renal function and retinopathy in diabetic retinopathy patients using OCTA detection.

Objective: To investigate the correlation between glucose and lipid metabolism, renal function, and retinopathy in patients with diabetic retinopathy (DR) based on optical coherence tomography angiography (OCTA).

Methods: A total of 584 diabetic patients who underwent treatment at The Second Affiliated Hospital of Dalian Medical University from March 2022 to June 2023 were retrospectively selected as research participants. They were categorized into a NDR group (n=366) and a DR group (n=218) based on the presence or absence of DR.

In vitro co-culture models for studying organoids-macrophages interaction: the golden technology of cancer immunotherapy.

Macrophages, as the largest immune cell group in tumour tissues, play a crucial role in influencing various malignant behaviours of tumour cells and tumour immune evasion. As the research on macrophages and cancer immunotherapy develops, the importance of appropriate research models becomes increasingly evident. The development of organoids has bridged the gap between traditional two-dimensional (2D) cultures and animal experiments.

Influencing factors of particle deposition in the human nasal cavity.

Objective: To review the existing literature on the application of computational fluid dynamics methods to study nasal particle deposition and to summarize and analyze the factors affecting nasal particle deposition in order to provide theoretical references for the development of future transnasal drug delivery devices and the prevention of respiratory-related diseases.

Psychological factors may affect the quality of life in irritable bowel syndrome patients more than the gut itself? A multicenter cross-sectional study.

Background And Aim: Both intestinal symptoms and comorbidities exist in irritable bowel syndrome (IBS) patients and influence their quality of life (QOL). More research is needed to determine how these variables impact the QOL of IBS patients. This study aimed to determine which specific factors had a higher influence on QOL and to further compare the effects of intestinal symptoms and comorbidities on QOL.

The current status and novel advances of boron neutron capture therapy clinical trials.

Boron neutron capture therapy (BNCT) is a treatment method that focuses on improving the cure rate of patients with cancer who are difficult to treat using traditional clinical methods. By utilizing the high neutron absorption cross-section of boron, material rich in boron inside tumor cells can absorb neutrons and release high-energy ions, thereby destroying tumor cells. Owing to the short range of alpha particles, this method can precisely target tumor cells while minimizing the inflicted damage to the surrounding normal tissues, making it a potentially advantageous method for treating tumors.

Ginsenoside Rg3 decreases breast cancer stem-like phenotypes through impairing MYC mRNA stability.

Breast cancer stem cells (BCSCs) are responsible for breast cancer metastasis, recurrence and treatment resistance, all of which make BCSCs potential drivers of breast cancer aggression. Ginsenoside Rg3, a traditional Chinese herbal medicine, was reported to have multiple antitumor functions. Here, we revealed a novel effect of Rg3 on BCSCs.
