Chemotherapeutics are most often used to treat cancer, but side effects, drug resistance, and toxicity often compromise their effectiveness. In contrast, phytocompound plumbagin possesses a distinct pleiotropic nature, targeting multiple signaling pathways, such as ROS generation, cell death, cellular proliferation, metastasis, and drug resistance, and is shown to enhance the efficacy of chemotherapeutic drugs. Plumbagin has been shown to act synergistically with various chemotherapeutic drugs and enhance their efficacy in drug-resistant cancers. The pleiotropic nature is believed to be due to plumbagin's unique structure, which contains a naphthoquinone ring and a hydroxyl group responsible for plumbagin's various biological responses. Despite limitations such as restricted bioavailability and delivery, recent developments aim to address these challenges and harness the potential of plumbagin as an anticancer therapeutics. This review delves into the structural aspect of the plumbagin molecule contributing to its pleiotropic nature, explores the diverse mechanism that it targets, and discusses emerging strategies to overcome its limitations.

Since its discovery, IL-1β has taken center stage as a key mediator of a very broad spectrum of diseases revolving around immuno-mediated and inflammatory events. Predictably, the pleiotropic nature of this cytokine in human pathology has led to the development of targeted therapeutics with multiple treatment indications in the clinic. Following the accumulated findings of IL-1β's central modulatory role in the immune system and the implication of inflammatory pathways in cancer, the use of IL-1β antagonists was first proposed and then also pursued for oncology disorders.

Advancements in single-cell multimodal techniques have greatly enhanced our understanding of disease-relevant loci identified through genome-wide association studies (GWASs). To investigate the biological connections between the eye and brain, we integrated bulk and single-cell multiomic profiles with GWAS summary statistics for eight neuropsychiatric and five ocular diseases. Our analysis uncovered five latent factors explaining 61.

Unlabelled: Interlinked interactions between the viral capsid (CA), nucleoporins (Nups), and the antiviral protein myxovirus resistance 2 (MX2/MXB) influence human immunodeficiency virus 1 (HIV-1) nuclear entry and the outcome of infection. Although RANBP2/NUP358 has been repeatedly identified as a critical player in HIV-1 nuclear import and MX2 activity, the mechanism by which RANBP2 facilitates HIV-1 infection is not well understood. To explore the interactions between MX2, the viral CA, and RANBP2, we utilized CRISPR-Cas9 to generate cell lines expressing RANBP2 from its endogenous locus but lacking the C-terminal cyclophilin (Cyp) homology domain and found that both HIV-1 and HIV-2 infections were reduced significantly in RANBP2 cells.
