Multiple sclerosis (MS) is an immune-mediated inflammatory disease that leads to demyelination and neuronal loss in the central nervous system. Immune cells of lymphoid and myeloid origin play a significant role in the initiation and amplification of neuronal inflammation in MS. STAT3 signaling plays a pivotal role in both myeloid and lymphoid immune cells, such as neutrophils and CD4+ T cells, through regulation of their inflammatory potential. Dysregulation in STAT3 signaling in myeloid and lymphoid cell compartments has been reported in MS. In this report, we attempted to investigate the effect of a small molecular inhibitor of STAT3, i.e., Stattic, in a relapsing-remitting (RR) model of experimental autoimmune encephalomyelitis (EAE). The effect of Stattic was investigated for clinical features, oxidative stress parameters, and Th17-related signaling in both the periphery and brain of SJL/J mice. Our data report that p-STAT3 expression is elevated in granulocytes, CD4+ T cells, and brain tissue in myelin proteolipid protein (PLP)-immunized SJL/J mice, which is associated with the presence of clinical symptoms and upregulation of inflammatory markers in these cells/tissues. Treatment with Stattic leads to the amelioration of disease symptoms and attenuation of inflammatory markers in neutrophils (iNOS/nitrotyrosine/IL-1β), CD4+ T cells (IL-17A/IL-23R), and brain tissue (IL-17A/iNOS/IL-1β/MPO activity/lipid peroxides) in mice with EAE. These data suggest that the blockade of STAT3 signaling in cells of lymphoid and myeloid origin may cause the attenuation of systemic and neuronal inflammation, which could be responsible for the amelioration of disease symptoms in an RR model of EAE. Therefore, pharmacological inhibition of STAT3 in RRMS could be a potential therapeutic strategy.

Exonuclease 1 (EXO1) is an evolutionarily conserved exonuclease, which have function on maintaining genomic stability. Elevated expression of EXO1 has been reported in certain cancers. However, a comprehensive pan-cancer analysis of EXO1 is still lacking and its role in human cancer development remains poorly understood.

Chronic myeloid leukemia (CML) typically progresses from a chronic phase to an accelerated phase, and eventually to a blast crisis, often involving the bone marrow and peripheral blood, if left untreated. Central nervous system (CNS) involvement is an uncommon manifestation of CML, particularly as an isolated CNS relapse. Here, we present a rare case of CML in lymphoid blast crisis with an isolated CNS relapse.

Acute leukemias of ambiguous lineage (ALAL) is a rare type of acute leukemia, referring to a group of disorders characterized by a combination of myeloid, lymphoid, or more lineages, whose incidence is significantly lower in children than adults. Here, we summarized the clinical features and outcomes of 36 pediatric ALAL patients in past 16 years. The patients diagnosed as ALAL based on the criteria of EGIL scoring system in 1998 (EGIL 1998) and/or the 2016 revisions to the WHO classification (WHO 2016) from January 1, 2005 to December 1, 2021 were included, respectively.

Background: Muscle stem cells (MuSCs) undergo numerous state transitions throughout life, which are critical for supporting normal muscle growth and regeneration. Epigenetic modifications in skeletal muscle play a significant role in influencing the niche and cellular states of MuSCs. Mixed-lineage leukemia 4 (Mll4) is a histone methyltransferase critical for activating the transcription of various target genes and is highly expressed in skeletal muscle.

This study explores the epigenetic mechanism of MLL1 regulating trophoblast ferroptosis in preeclampsia (PE). A murine model of PE was established, and HTR-8/SVneo cells were induced by Erastin to establish an in vitro cell model. GSH, MDA, Fe, and ROS levels were measured to assess ferroptosis.
