(SH) is a seaweed that has several features that benefit health. In this study, we investigated the immune-enhancing effect of SH, focusing on the role of spleen-mediated immune functions. Chromatographic analysis of SH identified six types of monosaccharide contents, including mannose, rhamnose glucose, galactose xylose and fucose. SH increased cell proliferation of primary cultured naïve splenocytes treated with or without cyclophosphamide (CPA), an immunosuppression agent. SH also reversed the CPA-induced decrease in Th1 cytokines. In vivo investigation revealed that SH administration can increase the tissue weight of major immune organs, such as the spleen and thymus. A similar effect was observed in CPA-injected immunosuppressed BALB/c mice. SH treatment increased the weight of the spleen and thymus, blood immune cell count and Th1 cytokine expression. Additionally, the YAC-1-targeting activities of natural killer cells, which are important in innate immunity, were upregulated upon SH treatment. Overall, our study demonstrates the immune-enhancing effect of SH, suggesting its potential as a medicinal or therapeutic agent for pathologic conditions involving immunosuppression.

Vulvovaginal candidiasis (VVC) represents the second cause of vaginal infections in childbearing-age women. It mainly affects the vulva and vagina; however, other organs can be compromised, with consequences that are not well known yet. To evaluate the ability of Candida albicans, inoculated into the vaginal lumen of mice, to migrate to the uterus and ovaries.

Purpose: Ovarian clear cell carcinoma is a highly malignant gynecological tumor characterized by a high rate of chemotherapy resistance and poor prognosis. The PI3K/AKT/mTOR pathway is well-known to be closely related to the progression of various malignancies, and recent studies have indicated that this pathway may play a critical role in the progression and worsening of OCCC.
Methods: In this study, we investigated the combined effects of WX390, a dual inhibitor of PI3K/mTOR, and cisplatin on OCCC through both in vitro and in vivo experiments to further elucidate their therapeutic effects.

Recent studies on head and neck squamous cell carcinoma (HNSCC) tumorigenesis have revealed several dysregulated molecular pathways. The phosphatidylinositol-3-kinase (PI3K) signaling pathway is frequently activated in HNSCC, making it an attractive target for therapies. PHT-427 is a dual inhibitor of PI3K and the mammalian target of AKT/PDK1.

Background: The most common malignant type of kidney cancer is clear cell renal cell carcinoma (ccRCC). The expression levels of hyaluronan-mediated motility receptor (HMMR) in many tumor types are significantly elevated. HMMR is closely associated with tumor-related progression, treatment resistance, and poor prognosis, and has yet to be fully investigated in terms of its expression patterns and molecular mechanisms of action in ccRCC.

Background: Bone marrow mesenchymal stem cells (BMSCs) are a crucial component of the tumor microenvironment (TME), with hypoxic conditions promoting their migration to tumors. Exosomes play a vital role in cell-to-cell communication within the TME. Hypoxic TME have a great impact on the release, uptake and biofunctions of exosomes.
