Summary: This study analyzed the mutation frequency of IDH1 and IDH2 genes in various cancers and found that they are most commonly mutated in gliomas. The mutations in these genes are associated with better overall survival and progression-free survival in gliomas.

Summary: Mutations in both IDH1 and IDH2 play an important role in the development of gliomas, but the co-occurrence of IDH1 and IDH2 mutations in the same tumor is rare. This study describes a case of an IDH-mutant astrocytoma with both IDH1 and IDH2 mutations, and the patient remains disease-free after nine and a half years. Interrogation of cancer genomic databases and a systematic review confirm the rarity of the concurrent mutations.

Summary: Most diffuse gliomas are reported to have IDH mutations, although in clinical practice, results are often negative. This study found that IDH1 mutations had different frequencies in different types of gliomas, while IDH2 mutations were relatively rare. Patients with IDH1/2-wildtype anaplastic astrocytomas had poor prognosis similar to glioblastomas.

Summary: IDH2 mutations in T-ALL are associated with older age, an immature phenotype, more frequent RAS gain-of-function mutations, and epigenetic regulator loss-of-function alterations. Conversely, IDH1 mutations appeared to be an independent prognostic factor in multivariate analysis.

Summary: This study demonstrates for the first time that ferroptosis is not active in most inflammatory ICCs and its activation is related to IDH1-2 status, supporting the therapeutic potential of ferroptosis-inducer drugs in ICC patients.

Summary: This study aimed to identify novel molecules that could simultaneously inhibit IDH1 and IDH2 for the management of glioblastoma and other cancers. Through molecular docking, simulations, and molecular dynamics analysis, four potential compounds were identified. These compounds showed maximum interaction with crucial amino acids in IDH1 and IDH2 and could potentially combat glioblastoma. However, further in vitro and in vivo studies are needed to validate the findings of this study.

Summary: Somatic mutations in the isocitrate dehydrogenase genes IDH1 and IDH2 are common in various tumor types, with gliomas showing a particularly high frequency of the IDH1(R132H) mutation. Patients with IDH1(R132H) mutations tend to have lower DNA methylation levels and higher gene expression compared to other IDH1/2 mutations. The different prognosis between IDH1(R132H) mutated astrocytomas and non-R132H IDH1/2-mutated astrocytomas highlights the clinical relevance of distinct IDH mutations.

Summary: This study aimed to assess the feasibility of DNA methylation array for simultaneous detection of glioma biomarkers. The research found that a DNA methylation signature could specifically distinguish IDH1/IDH2 mutant tumors, and copy number analysis using the array could identify 1p19q co-deletion tumors.

Summary: Abnormal RAS/RAF signaling plays a critical role in glioma, with BRAF mutations and amplifications leading to different effects on patient survival. Patients with BRAF mutations are more likely to be male with glioblastoma multiforme, while those with BRAF amplifications often have mutations in IDH1/2, TP53, and ATRX. Patients with BRAF amplifications and IDH1/2 wild type genotype have poorer prognoses and may benefit from personalized targeted therapy.

Summary: This study investigated the association between assisted reproductive technology (ART) use and childhood cancer subtype. The results showed a higher ART use among children with osteosarcoma and hepatoblastoma. However, the association between multiple gestation and these cancer subtypes was not retained in multivariable models. Evaluating long-term health outcomes in children conceived by ART appears warranted.

Summary: There is limited understanding of how adverse childhood experiences (ACEs) affect neural biomarkers, particularly Brain Derived Neurotrophic Factor (BDNF) levels. A systematic review and meta-analysis was conducted, analyzing twenty-two studies to assess the impact of ACE exposure on BDNF levels. Overall, no significant difference was found in BDNF levels between ACE-exposed and unexposed groups. The study highlights the importance of analyte type and timing of sample collection in investigating the impact of ACE exposure on neural biomarkers.

Summary: Cytomegalovirus (CMV), a common herpesvirus, has a significant impact on the immune system of the host. Congenital cytomegalovirus (cCMV) infection affects immune cell compartments in newborns, but the effects on fetal immune cell development are not well understood. Recent studies have suggested a potential link between cCMV infection and increased risk of developing acute lymphoblastic leukemia (ALL) in childhood. This review examines the emerging evidence connecting CMV and ALL risk, discusses known causes of childhood ALL, and proposes possible mechanisms by which early-life CMV infection may contribute to increased ALL risk.

Summary: Precision medicine has greatly improved the clinical care for cancer patients by developing targeted therapies, identifying inherited cancer predisposition syndromes, and optimizing pharmacotherapy through pharmacogenetics. It is argued that integrating pharmacogenomics into paired germline/somatic genomic testing would be an efficient method for increasing access to pharmacogenomic testing.

Summary: FET-PET has the potential to impact adjuvant radiotherapy planning, differentiate between treatment-induced pseudoprogression and true tumor progression, and predict prognosis in glioblastoma management. The FIG study is a multicenter phase II study aiming to investigate the impact of FET-PET versus standard MRI on radiotherapy volume delineation and the accuracy and management impact of FET-PET in distinguishing pseudoprogression from true tumor progression.

Summary: Human cytomegalovirus (HCMV) is a common vertically transmitted infection worldwide, but there are currently no vaccines or therapeutics to prevent congenital HCMV (cCMV) infection. Recent evidence suggests that antibody Fc effector functions may play an important role in maternal immunity against HCMV. This study demonstrates that antibody-dependent cellular cytotoxicity (ADCC) activation is associated with a lower risk of cCMV transmission, providing insights for future research and vaccine development.

Summary: Gliomas are prevalent neurological cancers in the USA, and effective treatment options are limited. Understanding the complex genetic variations and pathway associations of these cancers is crucial for developing new and effective therapies. Mutations in the Capicua gene (CIC) are more common in oligodendroglioma than in low-grade astrocytoma or glioblastoma. CIC mutations are observed in all glioma subtypes, while MAPK-associated mutations are most prevalent in CIC wild-type tissue. However, MAPK activation is enhanced in CIC-mutated oligodendroglioma, highlighting the importance of CIC as a genetic marker for MAPK activation.
