VDR expression was assessed in 319 primary breast cancer patients using the Remmele and Stegner immunoreactive scoring (IRS) system. Follow-up data were obtained from the Munich Cancer Registry. The correlation with overall survival (OS) and disease-free survival (DFS) was calculated using univariate and multivariate analyses. Correlation analysis revealed a correlation between nuclear VDR expression and improved outcomes for both OS (<i>p</i>=0.004) and DFS (<i>p</i>=0.001). Conversely, cytoplasmic VDR expression was significantly associated with a shorter OS (<i>p</i>=0.003) and DFS (<i>p</i><0.001). Additionally, both cytoplasmic and nuclear VDR expression were found to be independent markers of DFS (<i>p</i><0.001; <i>p</i>=0.021) when examined alongside clinicopathological parameters. Moreover, nuclear VDR expression was positively associated with lower lymph node invasion (pN; <i>p</i>=0.01). For triple-negative patients, cytoplasmic VDR expression was found to have a significant inverse correlation with DFS (<i>p</i><0.001). Lastly, the ratio of VDR nuclear/cytoplasmic was identified as an auxiliary independent marker of DFS and OS. These findings strongly indicate that the subcellular localization of VDR is crucial in determining BC prognosis. The expression of nuclear VDR appears to have a protective effect, while cytoplasmic VDR is associated with a more aggressive disease course.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma (NHL) subtype and is characterized by high clinical and biological heterogeneity.

The role of effector immune cells in the development and progression of DLBCL is complex and involves reciprocal interactions between tumor cells, adaptive and innate immune cells, their soluble mediators, and structural components present in the TME. Recruitment of immune cells in the TME and their distinct effects on tumor progression and therapeutic outcomes in the presence of therapy have decisive effects on the outcome of therapy. In this review, we discuss the application and implications of binary therapy involving suboptimal-dose chemotherapy and adoptive cell therapy on the basis of our recent findings on γc cytokine-aided cross-talk between dendritic cells and natural killer cells in therapy against experimental murine lymphoma.

This review delves into the intricate biology of fish ovaries, highlighting their structural diversity and the hormonal regulation that governs ovarian development and oocyte maturation. Key hormones include pituitary gonadotropins (GTHs) and maturation-inducing hormones (MIHs), which initiate oocyte growth and maturation. GTHs stimulate ovarian production of estradiol-17β and 17α,20β-DP, which induce oocyte maturation via MPF formation. Sex steroids like estrogens and progestogens, synthesized from cholesterol, play crucial roles. Other hormones, including growth hormone, prolactin, thyroid hormones, IGFs, ACTH, and melatonin, influence ovarian activity. The review also explores the varied reproductive strategies among fish, including oviparity and viviparity, and discusses how environmental factors like water temperature and photoperiod influence ovarian histology. Understanding the complex interplay between these factors is essential for advancing fisheries management, conservation, and aquaculture practices. Additionally, the evolutionary trajectory of fish ovaries underscores their adaptation to diverse ecological niches, contributing to the survival and reproductive success of fish species. The ovarian stroma provides structural support and houses various cell types, including dendritic cells (DCs), endocrine cells, and telocytes, contributing to follicle growth and hormone production, essential for reproductive success in fish.
