Prostate cancer (PCa) is the most common malignancy in men. Although mortality from PCa has been declining over the past decade, metastasis can substantially shorten survival time and remains a major challenge in maintaining quality of life for survivors. PCa cells preferentially metastasize to bone and typically result in osteoblastic lesions. In the late stages of disease, however, osteolytic lesions are observed. The mechanisms of PCa bone metastasis are still unclear, but relationships between the PCa cells and the bone tissue elements are suspected of being more complex than initially thought. Far from being an innocent bystander, the bone participates actively in the metastatic process and provides the cancer cells with growth factors and a fertile environment. Among the various cells in the bone environment, osteoblasts have a central role through their bidirectional interactions with the PCa cells. This review discusses the possible mechanisms of PCa bone metastasis and highlights the essential role of osteoblasts in the metastasis of PCa to bone.

Background: In neurodegenerative disease such as Alzheimer's disease and stroke, the brain transitions to pro-inflammatory profile, where microglia and T-cells in the brain have increase inflammatory profiles, along with increased Kv1.3 potassium channel abundance. Pharmacological blockade of Kv1.

Background: Caffeic acid (CA), a dietary compound, has been studied for its potential impact on inhibiting prostate cancer (PCa) growth. PCa is often associated with heightened expression of glyoxalase-1 (Glo-1), making it a target for potential therapeutic interventions. CA's mechanisms in suppressing Glo-1 expression and its effects on PCa cell proliferation are areas of interest for understanding its potential as an anticancer agent.

Aggressive prostate cancer (PCa) variants associated with androgen receptor signaling inhibitor (ARSI) resistance and metastasis remain poorly understood. Here, we identify the axon guidance semaphorin receptor PlexinD1 as a crucial driver of cancer aggressiveness in metastatic castration-resistant prostate cancer (CRPC). High PlexinD1 expression in human PCa is correlated with adverse clinical outcomes.

Since the establishment of the COVID-19 pandemic, a range of studies have been developed to understand the pathogenesis of SARS-CoV-2 infection, vaccine development, and therapeutic testing. However, the possible impacts that these viruses can have on non-target organisms have been explored little, and our knowledge of the consequences of the COVID-19 pandemic for biota is still very limited. Thus, the current study aimed to address this knowledge gap by evaluating the possible impacts of oral exposure of C57Bl/6 J female mice to SARS-CoV-2 lysate protein (at 20 µg/L) for 30 days, using multiple methods, including behavioral assessments, biochemical analyses, and histopathological examinations.

Nasopharyngeal carcinoma (NPC) refers to a cancerous tumor that develops in the upper and side walls of the nasopharyngeal cavity. Typically, individuals are often diagnosed with the disease when it has already progressed significantly, and those with advanced NPC tend to have an unfavorable outlook in terms of response rate to targeted treatments and overall clinical survival. Various molecular mechanisms, including Myeloid-derived suppressor cells and factors like PD-L1, have been explored to enhance the outcome of NPC.
