Oncogenic < em > BRAF < /em > < sup > V600E < /sup > induces microglial proliferation through extracellular signal-regulated kinase and neuronal death through c-Jun N-terminal kinase
Neural Regen Res. 2023 Jul;18(7):1613-1622. doi: 10.4103/1673-5374.361516.ABSTRACTActivating V600E in v-Raf murine sarcoma viral oncogene homolog B (BRAF) is a common driver mutation in cancers of multiple tissue origins, including melanoma and glioma. BRAFV600E has also been implicated in neurodegeneration. The present study aims to characterize BRAFV600E during cell death and proliferation of three major cell types of the central nervous system: neurons, astrocytes, and microglia. Multiple primary cultures (primary cortical mixed culture) and cell lines of glial cells (BV2) and neurons (SH-SY5Y) were employed. BRAFV600E ...

SIRT3 Promotes the Development of Esophageal Squamous Cell Carcinoma by Regulating Hexokinase 2 through the AKT Signaling Pathway
In the present study, we explored whether sirtuin-3 (SIRT3) regulates the proliferation and migration of esophageal squamous cell carcinoma (ESCC) and investigated the mechanisms underlying the oncogene role of SIRT3. siRNA was used to transfect Eca109 cells and downregulate SIRT3. The proliferation and migration of Eca109 cells were examined by the CCK-8 assay, colony formation assay, Transwell assay, and scratch test. Quantitative real-time PCR and Western blotting were used to detect SIRT3, hexokinase 2, AKT, and p-AKT in Eca109 cells. Functional assays showed that downregulation of SIRT3 could inhibit the proliferation...

GSE140966 RNA-Seq profiling of circular RNAs and the oncogenic role of circPVT1 in cutaneous squamous cell carcinoma
Contributors : Shuang Chen ; Chundi HeSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensCircular RNAs(circRNAs),which are a type of non-coding RNA with a special structure, have attracted the attention of researchers in recent years.As a high throughput gene screening method, RNA-seq has been widely used in tumor research.In present study,we assessed the expression pattern of circRNAs in CSCC via RNA-seq on CSCC and matched paracancerous samples. We further identified circPVT1 as being overexpressed in CSCC tissues and cells.Subsequently, we identified the characteristics of circPVT1 in...

Gallic Acid has an inhibitory effect on skin squamous cell carcinoma and acts on the heat shock protein HSP90AB1
Gene. 2022 Nov 11:147041. doi: 10.1016/j.gene.2022.147041. Online ahead of print.ABSTRACTDifferences in the features of aggressiveness of non-melanoma skin cancer (NMSC) subtypes, between basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are relevant characteristics. Comparing the characteristics between NMSC subtypes might help identify molecules associated with cancer metastasis and invasion. Considering these facts, the current study aimed to identify a molecular target for inhibiting skin cancer metastasis and invasion. Proteomic analysis suggested that heat shock protein 90 kDa, alpha, class B member 1 (HSP...

Silencing of SiX-4 enhances the chemosensitivity of melanoma cells to Cisplatin
In this study, we investigated whether silencing of SIX4 in a melanoma cell line (A375 cells) in combination with Cisplatin can affect the apoptosis and suppression of cell cycle progression, migration of the melanoma cells. MTT test and colony formation assay was applied to determine the IC50 of Cisplatin and the combined effect of SIX4 siRNA and Cisplatin on the viability and clonogenesis of the A-375 cells. qRT-PCR was performed to determine the c-myc, BCL-2, BAX, MMP-9, CXCR4, and Rock genes expression. Furthermore, flow cytometry was applied to evaluate apoptosis, autophagy, and the cell cycle status in different grou...
