Summary: P53 protein, derived from the P53 gene, is a well-known tumor suppressor gene. Its function and mechanisms in anti-neoplasms have been studied for many years. While previous research has largely focused on other organs and systems, recent studies have indicated that P53 also plays a significant role in CNS tumors, cerebral stroke, and neurodegenerative diseases. This review aims to summarize the research achievements on the relationship between P53 and CNS diseases, providing new insights for future studies.

Summary: Metastatic melanoma, a highly aggressive tumor, is often characterized by mutations in the MAPK pathway, particularly in the protein kinase BRAF. However, resistance to BRAF inhibitors is a major obstacle in melanoma treatment, with the reactivation of MAPK or PI3K/AKT pathways and the involvement of the p53 pathway contributing to acquired resistance. In melanoma, the canonical tumor suppressor p53 is frequently inactivated through various mechanisms. The TP53 gene and its family members TP63 and TP73 encode multiple protein isoforms with diverse functions in tumorigenesis. Some p53 isoforms are expressed in melanoma cells and have been shown to play specific roles in proliferation, survival, metastasis, invasion, migration, and treatment response. Particularly, p53 isoforms involved in acquired resistance to MAPK inhibitors present potential therapeutic targets to overcome resistance in melanoma.

Summary: The RUNX family plays a crucial role in neural crest cell differentiation and may also be involved in neuroblastoma tumorigenesis. Its function in tumor development can vary depending on the specific context, including the response to chemotherapy. In primary neuroblastomas, RUNX3 acts as a tumor suppressor, while RUNX1 regulates cell proliferation in a dual manner influenced by genetic and epigenetic factors, including MYCN. This review focuses on the mechanism through which the RUNX family regulates neurotrophin receptors (Trk family) associated with neuroblastoma aggressiveness, as well as their potential involvement in functional alterations of the p53 family members in neuroblastoma tumorigenesis. Understanding the contribution of the RUNX family to neuroblastoma tumorigenesis is crucial for future molecular-based therapies.

Summary: Outcomes for patients with osteosarcoma have remained stagnant for more than 3 decades, and the search for novel therapeutic agents is crucial. This study shows that Pramlintide, an FDA-approved drug for type 2 diabetes, may have potential efficacy against osteosarcoma by interfering with tumor glycolysis and leading to decreased cell growth and increased cell death. Injection of Pramlintide into osteosarcoma tumor nodules resulted in significantly smaller tumors, indicating its potential as a novel therapeutic approach for relapsed osteosarcoma patients.

Summary: Members of the p53 family, including p53, p63, and p73, share high homology but can be activated differently and have distinct roles in different tissues. By predicting interaction partners and modeling their 3D structures, we gain insights into the functions and mechanisms of these family members.

Summary: p53 family members p53, p63, and p73 have tumor suppressor function, but p53 has a high mutation rate in cancers causing loss of its function. This review discusses drug therapies for nonsense and missense mutations in p53, and proposes p63 and p73 activators as potential anti-cancer drugs to replace mutant p53. Strategies to improve the response of these activators, particularly for p53 gain-of-function mutants, are also discussed.

Summary: Pirh2, a member of the RING-H2 family, has been identified as a key regulator of AIP4, inhibiting p73 function by downregulating AIP4 expression and ubiquitinating it. Despite AIP4's role in promoting p73 ubiquitination and degradation, Pirh2's interaction can disrupt the AIP4-p73 negative regulatory pathway and maintain p73 cell cycle arrest function.

Summary: Ovarian high-grade serous carcinoma (HGSC) is a lethal malignancy with early detection and late-stage treatment challenges. This study developed an in vitro model of HGSC based on a TP53 mutation in mouse oviductal epithelial cells. The results showed that cells expressing missense mutant p53(R175H) had increased spheroid survival and anchorage-independent growth, and highlighted the potential anti-apoptosis gain-of-function mechanism of p53(R175H).

Summary: Apoptosis is a crucial process in maintaining cellular balance and development in the ovarian reserve. While a large number of oocytes are generated in the fetal ovary, most of them undergo apoptosis before birth. During puberty, primordial follicles develop into mature follicles, but only one dominant follicle is selected for ovulation, while smaller ones undergo apoptosis. The molecular mechanism of oocyte death is still not fully understood, despite extensive studies. This review discusses the roles of apoptosis regulators and the transcription factor p63 in oocyte death and survival.

Summary: We report a case of a pediatric patient with Crohn disease who presented with a non-Meckel diverticulum in the colonic wall of the cecum. This is the first report of such a diverticulum in a child with Crohn disease and we examine the underlying mechanics. The diverticulum formed at the site of maximum stricture and weakest point in the bowel wall due to the inflammatory bowel disease. The time interval between diagnosis of ileocecal stricture and surgery was important for the development of this diverticulum. Continued follow-up in adulthood is necessary due to the increased risk of intestinal diverticular disease and neoplasms in patients with Crohn disease.

Summary: SARS-CoV-2 induces immune-mediated type 1 interferon production, which leads to exacerbated interferonopathies. Aspirin inhibits cGAS-mediated signaling to regulate immune response. Additionally, aspirin and dapsone inhibit the activation of IFN-1 and NF-kappa B by targeting cGAS. Timely alleviation of the pathologic course is necessary for immune cell reactions and viral clearance.

Summary: The tumor suppressor p53 is crucial in cancer pathogenesis and maintaining normal cell growth by regulating p53 expression. UBE4B is an E3/E4 ubiquitin ligase involved in a negative-feedback loop with p53, playing a role in its degradation. Therefore, targeting the p53-UBE4B interaction is a promising strategy for anticancer therapy. In this study, we found that the UBE4B U box does not bind to p53 but is essential for its degradation. Certain mutants of UBE4B lose their ability to degrade p53, and a SWIB/Hdm2 motif of UBE4B is vital for p53 binding. Furthermore, a novel UBE4B peptide activates p53 functions by blocking the p53-UBE4B interaction, suggesting a new approach for p53 activation therapy in cancer.

Summary: Factors such as population migration, tourism, dog translocations, and poor hygiene practices contribute to the spread of echinococcosis. Prompt diagnosis of cystic echinococcosis (CE) should be considered when a cyst-like mass is found in the liver or lung of individuals with a history of exposure to sheepdogs in endemic areas. Routine imaging techniques and serologic investigations are used for detection and confirmation. Treatment options for pediatric echinococcosis include drug therapy and surgical interventions.
