The Ets-1 transcription factor plays an important role in various physiological and pathological processes. These diverse roles of Ets-1 are likely to depend on its interaction proteins. We have previously showed that Ets-1 interacted with DNA-dependent protein kinase (DNA-PK) complex including its regulatory subunits, Ku70 and Ku86 and with poly (ADP-ribose) polymerase-1 (PARP-1). In this study, the binding domains for the interaction between Ets-1 and these proteins were reported. We demonstrated that the interaction of Ets-1 with DNA-PK was mediated through the Ku70 subunit and was mapped to the C-terminal region of Ets-1 and the C-terminal part of Ku70 including SAP domain. The interactive domains between Ets-1 and PARP-1 have been mapped to the C-terminal region of Ets-1 and the BRCA1 carboxy-terminal (BRCT) domain of PARP-1. The results presented in this study may advance our understanding of the functional link between Ets-1 and its interaction partners, DNA-PK and PARP-1.

Background: Atg7-autophagy-related gene 7 contributes as an immune cell function regulator, particularly involved in CD4⁺ T cell response. Nevertheless, the specific contribution of Atg7 in CD4⁺ T cells sensitive immune responses in inflammatory bowel disease (IBD) remains largely unclear. This study explores the functional significance and regulatory mechanisms of CD4⁺ T cell-specific Atg7 in IBD.

Understanding diseases as the result of continuous transitions from a healthy system is more realistic than understanding them as discrete states. Here, we designed the spectrum formation approach (SFA), a machine learning-based method that extracts key features contributing to disease state continuity. We applied the SFA to transcriptomic data from patients with progressive liver disease and neurodegenerative movement disorders to examine its effectiveness in identifying biologically relevant gene sets.

Following the publication of the above paper, it was drawn to the Editor's attention by a concerned reader that, regarding the western blots shown in Figs. 4B and 5B, the AMPK panel in Fig. 4B looked strikingly similar to the ATG5 panel in Fig.

The NF-κB family comprises five transcription factors (RELA, RELB, C-REL, NF-κB1 (p50) and NF-κB2 (p52)) that form homo- or heterodimers among themselves to regulate gene expression by binding DNA. Here we show that p52 activates transcription without directly binding DNA but as a heterotetrameric complex with ETS1, a transcription factor outside the NF-κB family. By generating a knock-in mouse model (Nfkb2) with three mutated residues on p52 required for its interaction with ETS1, but not RELB, we demonstrate that the p52-ETS1 complex regulates the expression of transcription factors OCT1 and OBF1, which are known to be critical for the germinal center program.

Background: The debate over the clinical role of atosiban in assisted reproduction continues. The purpose of our study was to explore the efficacy of atosiban on pregnancy outcomes of patients undergoing frozen embryo transfer.
Methods: A total of 1615 frozen embryo transfer cycles between 1 January 2019 and 31 December 2022 were included in this retrospective cohort study.
