PRMT1 promotes the proliferation and metastasis of gastric cancer cells by recruiting MLXIP for the transcriptional activation of the β-catenin pathway.

Protein arginine methyltransferase 1 (PRMT1), a type I PRMT, is overexpressed in gastric cancer (GC) cells. To elucidate the function of PRMT1 in GC, PRMT1 expression in HGC-27 and MKN-45 cells was knocked down by short hairpin RNA (shRNA) or inhibited by PRMT1 inhibitors (AMI-1 or DCLX069), which resulted in inhibition of GC cell proliferation, migration, invasion, and tumorigenesis and . MLX-interacting protein (MLXIP) and Kinectin 1 (KTN1) were identified as PRMT1-binding proteins.

ARIH2 regulates the proliferation, DNA damage and chemosensitivity of gastric cancer cells by reducing the stability of p21 via ubiquitination.

Ariadne homolog 2 (ARIH2) is a key member of the RING-between-RING (RBR) E3 ligase family, which is characterized by an RBR domain involved in the polyubiquitination process. However, the molecular mechanism and biological function of ARIH2 in the pathogenesis of gastric cancer remain unclear. In this paper, we found that high ARIH2 expression is correlated with poor prognosis in gastric cancer patients and that ARIH2 can significantly promote the proliferation of gastric cancer cells.

CBX3 accelerates the malignant progression of glioblastoma multiforme by stabilizing EGFR expression.

CBX3, also known as HP1γ, is a major isoform of heterochromatin protein 1, whose deregulation has been reported to promote the development of human cancers. However, the molecular mechanism of CBX3 in glioblastoma multiforme (GBM) are unclear. Our study reported the identification of CBX3 as a potential therapeutic target for GBM.

Lycorine hydrochloride inhibits melanoma cell proliferation, migration and invasion via down-regulating p21.

Lycorine hydrochloride (LH) is an active ingredient sourced from the medicinal herb . Previous studies have suggested that LH exerts tumor suppression activity in several human cancers. However, the anti-cancer effect of LH in melanoma and the potential molecular mechanisms still need to be further studied.

Zinc finger protein RP-8, the Bombyx mori ortholog of programmed cell death 2, regulates cell proliferation.

Programmed cell death 2 (PDCD2) is a highly conserved eukaryotic protein indispensable for various physiological processes such as cell proliferation, development, and apoptosis. In the present study, we identified a Zinc finger protein RP-8 from the silkworm, Bombyx mori (BmZfrp8), the ortholog of PDCD2 protein. The quantitative real-time PCR analysis revealed the ubiquitous distribution of BmZfrp8 in the different tissues; however, the gene's transcription level was highest in those of the silk gland, testis, and ovary.

Hedgehog promotes cell proliferation in the midgut of silkworm, Bombyx mori.

The Hedgehog (Hh) signaling pathway is one of the major regulators of embryonic development and tissue homeostasis in multicellular organisms. However, the role of this pathway in the silkworm, especially in the silkworm midgut, remains poorly understood. Here, we report that Bombyx mori Hedgehog (BmHh) is expressed in most tissues of silkworm larvae and that its functions are well-conserved throughout evolution.

20-Hydroxyecdysone regulates the transcription of the lysozyme via Broad-Complex Z2 gene in silkworm, Bombyx mori.

Broad-Complex Z2 (Br-C Z2) is an ecdysone inducible transcription factor that regulates physiological, innate immune and developmental events in insects. Here, we identified an orthologue of Br-C Z2 from silkworm, Bombyx mori (BmBr-C Z2) to study its involvement in immune responses. The quantitative real-time PCR analysis revealed that BmBr-C Z2 was expressed ubiquitously in all tested tissues under normal physiological conditions.

PHF19 promotes the proliferation, migration, and chemosensitivity of glioblastoma to doxorubicin through modulation of the SIAH1/β-catenin axis.

PHD finger protein 19 (PHF19), a critical component of the polycomb repressive complex 2 (PRC2), is crucial for maintaining the repressive transcriptional activity of several developmental regulatory genes and plays essential roles in various biological processes. Abnormal expression of PHF19 causes dysplasia or serious diseases, including chronic myeloid disorders and tumors. However, the biological functions and molecular mechanisms of PHF19 in glioblastoma (GBM) remain unclear.

Integrin β3 plays a novel role in innate immunity in silkworm, Bombyx mori.

Integrins are transmembrane receptors that play essential roles in many physiological and pathological processes through cell-to-cell and cell-to-extracellular matrix (ECM) interactions. In the current study, a 2653-bp full-length cDNA of a novel integrin β subunit (designated Bmintegrin β3) was obtained from silkworm hemocytes. Bmintegrin β3 has the typical conserved structure of the integrin β family.

[Cloning and characterization of BmBrat in silkworm, Bombyx mori].

NHL proteins, which play important roles in regulation of cell proliferation and differentiation, have been extensively studied on mammals. Here, we cloned a member of NHL protein family namely BmBrat in silkworm. The full-length cDNA sequence of BmB rat was obtained by means of the rapid amplification of cDNA ends (RACE), including 3 614 bp.

Molecular cloning, characterization and expression analysis of cathepsin O in silkworm Bombyx mori related to bacterial response.

Cathepsins are the main members of the cysteine family and play important roles in immune response in vertebrates. The Cathepsin O of Bombyx mori (BmCathepsin O) was cloned from the hemocytes by the rapid amplification of cDNA ends (RACE). The genomic DNA was 6131bp long with a total of six exons and five introns.
