ZNF703 promotes Triple-Negative breast cancer cell progression and in combination with STK11 predicts disease recurrence (ZS -TNBC Model).

Background: It is largely unidentified concerning the underlying genetic causes responsible for triple-negative breast cancers (TNBC), with unpredictable disease recurrence. This study aimed to examine the role of ZNF703 (Zinc finger 703) in the malignant behaviors of TNBC and its role in predicting disease-free survival (DFS).

Methods: After downregulation of ZNF703 with short interfering RNA (siRNA), we examined the proliferation of TNBC cell line MDA-MB-231 by sulforhodamine B (SRB) assay, the invasion of cells by a transwell invasion model, and the migration of cells by the monolayer wound-healing experiment.

NPC1 controls TGFBR1 stability in a cholesterol transport-independent manner and promotes hepatocellular carcinoma progression.

Niemann-Pick disease type C protein 1 (NPC1), classically associated with cholesterol transport and viral entry, has an emerging role in cancer biology. Here, we demonstrate that knockout of Npc1 in hepatocytes attenuates hepatocellular carcinoma (HCC) progression in both DEN (diethylnitrosamine)-CCl induced and MYC-driven HCC mouse models. Mechanistically, NPC1 significantly promotes HCC progression by modulating the TGF-β pathway, independent of its traditional role in cholesterol transport.

EIF4G2 Promotes Hepatocellular Carcinoma Progression via IRES-dependent PLEKHA1 Translation Regulation.

Hepatocellular carcinoma (HCC) is a highly lethal cancer, and proteomic studies have shown increased protein diversity and abundance in HCC tissues, whereas the role of protein translation has not been extensively explored in HCC. Our research focused on key molecules in the translation process to identify a potential contributor in HCC. We discovered that EIF4G2, a crucial translation initiation factor, is significantly upregulated in HCC tissues and associated with poor prognosis.

Proteomic analysis of DEN and CCl-induced hepatocellular carcinoma mouse model.

Hepatocellular carcinoma (HCC) seriously threatens human health, mostly developed from liver fibrosis or cirrhosis. Since diethylnitrosamine (DEN) and carbon tetrachloride (CCl)-induced HCC mouse model almost recapitulates the characteristic of HCC with fibrosis and inflammation, it is taken as an essential tool to investigate the pathogenesis of HCC. However, a comprehensive understanding of the protein expression profile of this model is little.

Proteomic overview of hepatocellular carcinoma cell lines and generation of the spectral library.

Cell lines are extensively used tools, therefore a comprehensive proteomic overview of hepatocellular carcinoma (HCC) cell lines and an extensive spectral library for data independent acquisition (DIA) quantification are necessary. Here, we present the proteome of nine commonly used HCC cell lines covering 9,208 protein groups, and the HCC spectral library containing 253,921 precursors, 168,811 peptides and 10,098 protein groups. The proteomic overview reveals the heterogeneity between different cell lines, and the similarity in proliferation and metastasis characteristics and drug targets-expression with tumour tissues.

: a new CRE driver to regulate gene expression in the otic placode lineage and other FGFR2b-dependent epithelia.

Pan-otic CRE drivers enable gene regulation throughout the otic placode lineage, comprising the inner ear epithelium and neurons. However, intersection of extra-otic gene-of-interest expression with the CRE lineage can compromise viability and impede auditory analyses. Furthermore, extant pan-otic CREs recombine in auditory and vestibular brain nuclei, making it difficult to ascribe resulting phenotypes solely to the inner ear.

Polysaccharides from Opuntia milpa alta alleviate alloxan-induced INS-1 cells apoptosis via reducing oxidative stress and upregulating Nrf2 expression.

The incidence and progression of type 2 diabetes are closely related to pancreatic β-cell damage. Oxidative stress may be one of the key factors contributing to β-cell apoptosis. Opuntia milpa alta polysaccharides (MAPs) are water-soluble macromolecular polysaccharides that have antidiabetic effects in vivo.

2 Hz EA Reduces Heroin Withdrawal-Induced Hyperalgesia and Heroin Relapse by Downregulating P2X3 Receptors in DRG Neurons.

Electroacupuncture (EA) has effective analgesic effects. Our previous study demonstrated that the upregulation of P2X3 receptors in the dorsal root ganglia (DRG) might participate in heroin withdrawal-induced hyperalgesia. The aim of this study is to further explore whether 2 Hz EA reduces heroin relapse associated with its analgesic effect and whether P2X3 receptors in the DRG are involved in this process.

Tea Polyphenols Attenuate Methamphetamine-Induced Neuronal Damage in PC12 Cells by Alleviating Oxidative Stress and Promoting DNA Repair.

DNA integrity plays a crucial role in cell survival. Methamphetamine (METH) is an illegal psychoactive substance that is abused worldwide, and repeated exposure to METH could form mass free radicals and induce neuronal apoptosis. It has been reported that free radicals generated by METH treatment can oxidize DNA and hence produce strand breaks, but whether oxidative DNA damage is involved in the neurotoxicity caused by METH remains unclear.
