Objective: This study aims to explore the correlation between X-linked inhibitor of apoptosis protein (XIAP) gene polymorphisms (rs8371 and rs9856) with the susceptibility and prognosis of esophageal squamous cell carcinoma (ESCC), providing a potential treatment for ESCC.
Method: A total of 170 ESCC patients (case group) and 191 healthy people (control group) were enrolled in our study. Genotyping was conducted on the basis of the ligase detection reaction (LDR). The expressions of XIAP polymorphisms were detected. The patients were followed up every three months until death or the last follow-up day. The overall survival (OS) and progression free survival (PFS) were recorded by Kaplan-Meier survival curve, and the relationship between XIAP gene polymorphism and risk and prognosis of ESCC was assessed by Cox multivariate analysis.
Result: TT+CT genotype and T allele frequencies of XIAP rs8371 and rs9856 in the case group were significantly lower compared to those of the control group (all P<0.05), suggesting that TT+CT genotype of XIAP rs8371 and rs9856 was associated with ESCC susceptibility. XIAP rs8371 and rs9856 polymorphisms were associated with tumor node metastasis (TNM) staging, depth of invasion and lymph node metastasis. The OS and PFS of TT+CT genotype carriers of rs8371 were longer than those of CC genotype carriers. Smoking, alcohol, TNM staging, depth of invasion, and lymph node metastasis were significantly associated with the OS and PFS in ESCC patients. Higher TNM staging, depth of invasion, and presence of lymph node metastasis were independent risk factors, while XIAP rs8371 was an independent protective factor for the prognosis of ESCC patients.
Conclusion: The present study demonstrates that XIAP rs8371 and rs9856 are associated with susceptibility to ESCC, and rs8371 polymorphisms might serve as an indicator for improved clinical efficacy and prognosis of ESCC patients.

Unlabelled: X-linked Lymphoproliferative Syndromes (XLP), which arise from mutations in the or genes, are characterized by the inability to control Epstein-Barr Virus (EBV) infection. While primary EBV infection triggers severe diseases in each, lymphomas occur at high rates with XLP-1 but not with XLP-2. Why XLP-2 patients are apparently protected from EBV-driven lymphomagenesis, in contrast to all other described congenital conditions that result in heightened susceptibility to EBV, remains a key open question.

Interleukin-18 (IL-18) serves a dual function in the immune system, acting as a "double-edged sword" cytokine. Depending on the microenvironment and timing, IL-18 can either drive harmful inflammation or restore immune homeostasis. Pathologies characterized by elevated IL-18, recently proposed to be termed IL-18opathies, highlight the therapeutic potential for IL-18 blockade.

Spinal cord injury (SCI) results in a cascade of primary and secondary damage, with apoptosis being a prominent cause of neuronal cell death. The X-linked inhibitor of apoptosis (XIAP) plays a critical role in inhibiting apoptosis, but its expression is reduced following SCI, contributing to increased neuronal vulnerability. This study investigates the regulatory role of miR-199a-5p on XIAP expression in the context of SCI.

In B-cell malignancies, the overexpression of MYC is associated with poor prognosis, but its mechanism underlying resistance to immunochemotherapy remains less clear. In further investigations of this issue, we show here that the pharmacological inhibition of MYC in various lymphoma and multiple myeloma cell lines, as well as patient-derived primary tumor cells, enhances their susceptibility to NK cell-mediated cytotoxicity induced by conventional antibodies targeting CD20 (rituximab) and CD38 (daratumumab), as well as T cell-mediated cytotoxicity induced by the CD19-targeting bispecific T-cell engager blinatumomab. This was associated with upregulation of the target antigen only for rituximab, suggesting additional escape mechanisms.
