Role of kinin receptors in skin pigmentation
Eur J Pharmacol. 2024 Apr 9:176537. doi: 10.1016/j.ejphar.2024.176537. Online ahead of print.ABSTRACTPrevious studies have shown that all kinin system is constitutively expressed in the normal and inflamed skin, with a potential role in both physiological and pathological processes. However, the understanding regarding the involvement of the kinin system in skin pigmentation and pigmentation disorders remains incomplete. In this context, the present study was designed to determine the role of kinins in the Monobenzone (MBZ)-induced vitiligo-like model. Our findings showed that MBZ induces higher local skin depigmentation i...

β-Lapachone, an NQO1 bioactivatable drug, prevents lung tumorigenesis in mice
In conclusion, our study suggests that long-term consumption of low-dose β-Lap could potentially be an effective therapeutic strategy for the prevention of lung premalignant lesions. However, further studies and clinical trials are necessary to validate our findings, determine the safety of long-term β-Lap usage in human, and promote the use of β-Lap in high-risk populations.PMID:38604545 | DOI:10.1016/j.ejphar.2024.176511 (Source: European Journal of Pharmacology)

GSK0660 enhances antitumor immunotherapy by reducing PD-L1 expression
Eur J Pharmacol. 2024 Apr 8:176565. doi: 10.1016/j.ejphar.2024.176565. Online ahead of print.ABSTRACTBlockade of PD-1/PD-L1 immune checkpoint is wildly used for multiple types of cancer treatment, while the low response rate for patients is still completely unknown. As nuclear hormone receptor, PPARδ (peroxisome-proliferator-activated receptor) regulates cell proliferation, inflammation, and tumor progression, while the effect of PPARδ on tumor immune escape is still unclear. Here we found that PPARδ antagonist GSK0660 significantly reduced colon cancer cell PD-L1 protein and gene expression. Luciferase analysis showed ...

Alteration in DNA methylation patterns: Epigenetic signatures in gastrointestinal cancers
This study highlights alterations in DNA methylation in GI cancers. Understanding epigenetic differences among GI cancers may improve targeted therapies and lead to the discovery of new diagnostic biomarkers.PMID:38593929 | DOI:10.1016/j.ejphar.2024.176563 (Source: European Journal of Pharmacology)

Ghrelin alleviates placental dysfunction by down-regulating NF- κB phosphorylation in LPS-induced rat model of preeclampsia
Eur J Pharmacol. 2024 Apr 7:176569. doi: 10.1016/j.ejphar.2024.176569. Online ahead of print.ABSTRACTIn our previous study, we uncovered that ghrelin promotes angiogenesis in human umbilical vein endothelial cells (HUVECs) in vitro by activating the Jagged1/Notch2/VEGF pathway in preeclampsia (PE). However, the regulatory effects of ghrelin on placental dysfunction in PE are unclear. Therefore, we applied Normal pregnant Sprague-Dawley (SD) rats, treated with lipopolysaccharide (LPS), to establish a PE-like rat model. The hematoxylin-eosin (HE) staining method and immunohistochemistry (IHC) technology were used to detect m...

Toosendanin inhibits T-cell proliferation through the P38 MAPK signalling pathway
Eur J Pharmacol. 2024 Apr 6:176562. doi: 10.1016/j.ejphar.2024.176562. Online ahead of print.ABSTRACTIn recent years, immunosuppressants have shown significant success in the treatment of autoimmune diseases. Therefore, there is an urgent need to develop additional immunosuppressants that offer more options for patients. Toosendanin has been shown to have immunosuppressive activity in vitro as well as effects on autoimmune hepatitis (AIH) in vivo. Toosendanin did not induce apoptosis in activated T-cells but did affect the survival rate of naive T-cells. Toosendanin did not affect the expression of CD25 or secretion of IL-...

Combining brief recall and ketamine treatment prevents stress-primed methamphetamine memory reinstatement via heightening mPFC GABA activity
This study aimed to assess whether brief recall of methamphetamine (MA) memory, when combined with ketamine (KE) treatment, may prevent stress-primed MA memory reinstatement. Combining 3-min recall and KE facilitated MA memory extinction and resistance to subsequent stress-primed reinstatement. Such combination also produced glutamate metabotropic receptor 5 (mGluR5) upregulation in animals' medial prefrontal cortex (mPFC) γ-amino-butyric acid (GABA) neuron. Accordingly, chemogenetic methods were employed to bi-directionally modulate mPFC GABA activity. Following brief recall and KE-produced MA memory extinction, intra-mP...

Continuous oral olanzapine or clozapine treatment initiated in adolescence has differential short- and long-term impacts on antipsychotic sensitivity than those initiated in adulthood
In this study we compared the short- and long-term behavioral effects of 21-day continuous oral olanzapine (7.5 mg/kg/day) or clozapine (30.0 mg/kg/day) administration in heathy or maternal immune activated adolescent (33-53 days old) or adult (80-100 days old) rats of both sexes. We used a conditioned avoidance response model to assess the drug-induced alterations in antipsychotic sensitivity. Here, we report that while under the chronic drug treatment period, olanzapine progressively increased its suppression of avoidance responding over time, especially when treatment was initiated in adulthood. Clozapine's suppression ...
