B-cell CLL/lymphoma 9 (BCL9) is considered a key developmental regulator and a well-established oncogenic driver in multiple cancer types, mainly through potentiating the Wnt/β-catenin signaling. However, increasing evidences indicate that BCL9 also plays multiple Wnt-independent roles. Herein, we summarized the updates of the canonical and non-canonical functions of BCL9 in cellular, physiological, or pathological processes. Moreover, we also concluded that the targeted inhibitors disrupt the interaction of β-catenin with BCL9 reported recently.

Schizophrenia is a complex neuropsychiatric disorder closely associated with genetic factors. Copy number variations (CNVs) play a key role in the genetic etiology of schizophrenia, with the distal 1q21.1 microdeletion identified as a rare CNV that serves as a significant genetic risk factor for the disorder.

Triple-negative breast cancer (TNBC) is characterised by an absence of the oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), for which there are few therapeutic options and the prognosis is poor. This research sought to explore the particular function of the long non-coding RNA (lncRNA) LINC01232 in TNBC and its regulatory impacts on the miR-516a-5p/BCL9 pathway. In this study, quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to determine the expression level of LINC01232 in TNBC tissues.

Background: Gastric cancer (GC) represents a significant therapeutic challenge due to its aggressive progression and limited treatment options, emphasizing the urgent need for novel therapeutic targets and strategies. Although PYGO1 functions as a Wnt co-transcriptional activator and chromatin effector, its role in cancer remains poorly characterized. This study aims to elucidate the role of PYGO1 in GC and uncover its regulatory mechanisms.

MEF2D fusions are found in a special subtype of B-cell precursor acute lymphoblastic leukemia (BCP-ALL) with poor prognosis. In this study, we conducted high-throughput drug screenings using cell line and ex vivo cell model harboring, respectively, MEF2D::HNRNPUL1(MH) and MEF2D::BCL9(MB), the two major MEF2D fusions. We identified CUDC-907 as a highly potent dual-target inhibitor of PI3K/HDAC, demonstrating remarkable efficacy in inducing robust lethality while maintaining selectivity for MEF2D fusion-expressing cells.

Aims: Colorectal cancer (CRC), driven by Wnt/β-catenin hyperactivation, relies on nuclear import of β-catenin, but the underlying mechanism is not fully clarified. Given that tumor necrosis factor receptor-associated factor 2 (TRAF2) is a positive regulator of Wnt signaling by directly interacting with β-catenin, we aim to demonstrate the role of TRAF2 in Wnt-induced β-catenin nuclear translocation.
Materials And Methods: Wild-type and TRAF2 knockout cells (generated via CRISPR-Cas9) were utilized to validate the role of TRAF2 in β-catenin nuclear translocation through immunofluorescence and nucleoplasm separation assay.
