Abstract Background: Caffeic acid (CA) is considered a promising phytochemical that has inhibited numerous cancer cell proliferation. Therefore, it is gaining increasing attention due to its safe and pharmacological applications. In this study, we investigated the role of CA in inhibiting the Interleukin-6 (IL-6)/Janus kinase (JAK)/Signal transducer and activator of transcription-3 (STAT-3) mediated suppression of the proliferation signaling in human prostate cancer cells. Materials and Methods: The role of CA in proliferation and colony formation abilities was studied using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay and colony formation assays. Tumour cell death and cell cycle arrest were… More >

Abstract Background: Metformin has pleiotropic effects beyond glucose reduction, including tumor inhibition and immune regulation. It enhanced the anti-tumor effects of programmed cell death protein 1 (PD-1) inhibitors in serine/threonine kinase 11 (STK11) mutant non-small cell lung cancer (NSCLC) through an axis inhibition protein 1 (AXIN1)-dependent manner. However, the alterations of tumor metabolism and metabolites upon metformin administration remain unclear. Methods: We performed untargeted metabolomics using liquid chromatography (LC)-mass spectrometry (MS)/MS system and conducted cell experiments to verify the results of bioinformatics analysis. Results: According to the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database, most… More > Graphic Abstract

Abstract Melatonin and abscisic acid, as major plant hormones, play important roles in the physiological and biochemical activities of crops, but the interaction between the two under salt stress is not yet clear. This study investigated the endogenous levels of melatonin and abscisic acid in rice by using exogenous melatonin, abscisic acid, and their synthetic inhibitors, and examined their interactions under salt stress. The research results indicate that melatonin and abscisic acid can improve rice salt tolerance. Melatonin alleviated the salt sensitivity caused by abscisic acid deficiency, increased antioxidant enzyme activity and antioxidant content in rice More >

Abstract Plant antifreeze proteins (AFPs) are special proteins that can protect plant cells from ice crystal damage in low-temperature environments, and they play a crucial role in the process of plants adapting to cold environments. Proteins with these characteristics have been found in fish living in cold regions, as well as many plants and insects. Although research on plant AFPs started relatively late, their application prospects are broad, leading to the attention of many researchers to the isolation, cloning, and genetic improvement of plant AFP genes. Studies have found that the distribution of AFPs in different species… More >

Abstract Breast cancer, a predominant global health issue, requires ongoing exploration of new therapeutic strategies. Palbociclib (PAL), a well-known cyclin-dependent kinase (CDK) inhibitor, plays a critical role in breast cancer treatment. While its efficacy is recognized, the interplay between PAL and cellular autophagy, particularly in the context of the RAF/MEK/ERK signaling pathway, remains insufficiently explored. This study investigates PAL’s inhibitory effects on breast cancer using both in vitro (MCF7 and MDA-MB-468 cells) and in vivo (tumor-bearing nude mice) models. Aimed at elucidating the impact of PAL on autophagic processes and exploring the potential of combining it with trametinib… More > Graphic Abstract

Abstract This study is the first to evaluate the phytochemical content and biological properties of Tunisian T. platyphyllos Scop. A total of 23 compounds of essential oils were identified by gas chromatography-mass spectrometry (GC-MS) analysis of bracts and fruit extracts. The results show that oxygenated monoterpenes were the dominant class of essential oils. The phenolic composition was investigated by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF). The analysis showed that the chemical profiles of the ethanolic extracts of bracts and fruits are substantially similar. The highest polyphenol content was found in the ethanolic extracts of the fruits (7.65… More > Graphic Abstract

Abstract Background: Apolipoprotein B mRNA editing catalytic polypeptide (APOBEC), an endogenous mutator, induces DNA damage and activates the ataxia telangiectasia and Rad3-related (ATR)-checkpoint kinase 1 (Chk1) pathway. Although cisplatin-based therapy is the mainstay for muscle-invasive bladder cancer (MIBC), it has a poor survival rate. Therefore, this study aimed to evaluate the efficacy of an ATR inhibitor combined with cisplatin in the treatment of APOBEC catalytic subunit 3B (APOBEC3B) expressing MIBC. Methods: Immunohistochemical staining was performed to analyze an association between APOBEC3B and ATR in patients with MIBC. The APOBEC3B expression in MIBC cell lines was assessed… More >

Abstract Background: The primary cause of treatment failure in patients with refractory or relapsed B-cell non-Hodgkin lymphoma (r/r B-NHL) is resistance to current therapies, and therapy-induced senescence (TIS) stands out as a crucial mechanism contributing to tumor drug resistance. Here, we analyzed SENEX/Rho GTPase Activating Protein 18 (ARHGAP18) expression and prognostic significance in doxorubicin-induced B-NHL-TIS model and r/r B-NHL patients, investigating its target in B-NHL cell senescence and the effect of combining specific inhibitors on apoptosis resistance in B-NHL-TIS cells. Methods: Raji cells were transfected with the human SENEX shRNA recombinant lentiviral vector (Sh-SENEX) and the empty vector… More >

Abstract Background: α7 nicotinic acetylcholine receptor (α7nAChR) has been demonstrated to be involved in numerous of inflammatory diseases. Cell pyroptosis is a kind of cell death accompanied by inflammation. Objectives: The objective of this work is to explore the function of α7nAChR on cell pyroptosis in cervical cancer cells. Methods: Immunoblotting, quantitative polymerase chain reaction, and enzyme-linked immunosorbent assay were employed to examine the function of α7nAChR on cell pyroptosis and metabolic changes. Results: Herein, we found that α7nAChR inhibition led to cell pyroptosis in HeLa and SiHa of cervical cancer cells, which was attributed to the… More >
