Insects possess an innate immune system that responds to invading microorganisms. In this study, a subtractive cDNA library was constructed to screen for immune response-related genes in the fat bodies of Antheraea pernyi (Lepidoptera: Saturniidae) pupa challenged with Escherichia coli. Four hundred putative EST clones were identified by suppression subtractive hybridization (SSH), including 50 immune response-related genes, three cytoskeleton genes, eight cell cycle and apoptosis genes, five respiration and energy metabolism genes, five transport genes, 40 metabolism genes, ten stress response genes, four transcription and translation regulation genes and 77 unknown genes. To verify the reliability of the SSH data, the transcription of a set of randomly selected immune response-related genes were confirmed by semi-quantitative reverse transcription-PCR (RT-PCR) and real-time quantitative reverse transcription-PCR (qRT-PCR). These identified immune response-related genes provide insight into understanding the innate immunity in A. pernyi.

Background: Tumor necrosis factor receptor-associated factor 3 (TRAF3)-interacting protein 3 (TRAF3IP3) expressed in various tumor cell. However, its role in hepatocellular carcinoma (HCC) was unclear. We aimed to demonstrate the relationship between TRAF3IP3 and HCC and explore the potential role of TRAF3IP3 in HCC.
Introduction: B-cell acute lymphoblastic leukemia (B-ALL) in adults often presents a poor prognosis. ID1 and ID3 genes have been identified as predictors of poor response in Colombian adult B-ALL patients, contributing to cancer development. In various cancer models, these genes have been associated with immune regulatory populations within the tumor immune microenvironment (TIME).

Calcineurin (CN), a serine/threonine protein phosphatase regulated by Ca and calmodulin, plays a crucial role in the immune response of bivalves. In this study, we examined the effects of gene silencing of the CN subunit (HcCnAα) in Hyriopsis cumingii on the expression of genes associated with the NF-κB signaling pathway, as well as the phosphorylation of the inhibitor of NF-κB (IκB), through RNA interference (RNAi), quantitative PCR (qPCR), and Western blot (WB) analyses. The IκB kinase (HcIKK) and B-cell CLL/lymphoma 10 (HcBcl10) genes of H.
Uterine corpus endometrial carcinoma (UCEC) is one of the most common malignant tumours of the female genital tract. In the occurrence, progression and prognosis of UCEC, chronic inflammation plays an important role, making it pivotal to identify inflammatory response-related endometrial diseases. The cytokine interleukin-33 (IL-33) plays significant roles in immune responses, and has been associated with inappropriate allergic reactions, autoimmune diseases, and cancer pathology.
Purpose: Colorectal medullary carcinoma is extensive lymphocyte infiltration and associated with an active immune response. However, studies to comprehensively explore the immune landscape and efficacy of immune checkpoint blockade therapy in MeC are limited.
Experimental Design: We screened 47 cases of MeC from Harbin Medical University Cancer Hospital cohort.
