Objective: 1 gene expression in the rat hypothalamus was investigated following administration of methanolic extract of (MEHS) to provide mechanistic evidence for the reproductive effect of the MEHS as a potential regulator of 1 gene (which directly controls the hypogonadal axis).
Materials And Methods: This experiment was done using fifteen (15) male rats with average weight of 148 g, randomly grouped into three (3) groups (A-C). Group A was the control group and received no treatment. Group B and C were orally administered with 200 mg/kg and 400 mg/kg of MEHS, respectively. The animals received the extract once a day for twenty-one (21) days. The hypothalamus was harvested on the last day of administration to investigate antioxidant levels, histopathology, and 1 gene expression.
Results: The relative expression of 1 gene in the group C was downregulated compared to the control group (p=0.023). No significant changes were seen in the antioxidant levels of the groups treated with MEHS when compared to the control. MEHS had no histopathological effects in the hypothalamus at both low (200 mg/kg) and high (400 mg/kg) doses.
Conclusion: High-dose MEHS lowers the expression of the 1 gene in the hypothalamus. However, this effect could not be explained by the oxidative profile or histology of the hypothalamus.

Introduction: Heavy metal pollution threatens the biodiversity and ecological equilibrium of the Nile River. This study investigates the impact of heavy metal pollution on aquatic animals such as Nile tilapia (Oreochromis niloticus) in the Damietta branch of the River Nile and El-Rayah El-Tawfeeky canal in Benha City in Egypt.
Methods: Fish and water samples were collected from the Damietta branch and El-Rayah El-Tawfeeky during the fall of 2022.

Background: Cutaneous melanoma is one of the most invasive and lethal skin malignant tumors. Compared to primary melanoma, metastatic melanoma (MM) presents poorer treatment outcomes and a higher mortality rate. The tumor microenvironment (TME) plays a critical role in MM progression and immunotherapy resistance.

Background: Mutations in gamma-secretase complex (GSC) genes are associated with hidradenitis suppurativa (HS), and toll-like receptor (TLR) 2 is elevated in HS lesions. However, it remains unclear whether TLR2 is upregulated in the skin lesions of patients with HS with GSC gene variants, and the role of its upregulation in the pathogenesis of this disease are unknown.
Objective: To investigate the role of TLR2 upregulation in NCSTN and PSENEN knockdown keratinocytes.

Chondrosarcoma is a type of bone cancer that originates from cartilage cells. In clinical practice, surgical resection is the primary treatment for chondrosarcoma, but chemotherapy becomes essential for patients with metastasis or tumors in surgically inaccessible sites. However, drug resistance often leads to treatment failure.

Objective: This study aimed to investigate the associations of multi-omics polygenic risk score (PRS) and rheumatoid arthritis (RA) to identify potential genes/proteins and biological pathways.
Methods: Based on multi-omics data from 48,813 participants in the INTERVAL cohort, we calculated multi-omics PRS for 13,646 mRNAs (RNASeq), 308 proteins (Olink), 2,380 proteins (SomaScan), 726 metabolites (Metabolon), and 141 metabolites (Nightingale). Using the generalized linear model, we first evaluated the associations between multi-omics PRS and RA in 58,813 UK Biobank participants.
