Article Abstract
Actin filament-associated protein 1-antisense RNA1 (AFAP1-AS1), a cancer-related long non-coding RNA, has been found to be upregulated in multiple types of cancers. AFAP1-AS1 is important for the initiation, progression and poor prognosis of many cancers, including nasopharyngeal carcinoma (NPC). However, the mechanism underlying the regulation of AFAP1-AS1 expression is not well-understood. In our study, the potential promoter region of AFAP1-AS1 was predicted by comprehensive bioinformatics analysis. Moreover, promoter deletion analysis identified the sequence between positions -359 and -28 bp as the minimal promoter region of AFAP1-AS1. The ChIP assay results indicate that the AFAP1-AS1 promoter is responsive to the transcription factor c-Myc, which can promote high AFAP1-AS1 expression. This study is the first to clone and characterize the AFAP1-AS1 promoter region. Our findings will help to better understand the underlying mechanism of high AFAP1-AS1 expression in tumorigenesis and to develop new strategies for therapeutic high expression of AFAP1-AS1 in NPC.

Entomopathogenic fungi such as Metarhizium acridum are pivotal for sustainable pest management, yet the industrial conidial production is hindered by low yields and environmental sensitivity. Transcriptional regulation provides key targets for engineering strain modification. AP-1 transcription factors (TFs) are well-known for their roles in fungal growth, development, conidiation, pathogenicity and stress tolerance across various fungi.

Myelination is essential for normal brain function, yet the mechanisms governing neuron-oligodendrocyte interactions that ensure proper myelination levels remain poorly understood. Here, we identify transcription factor EB (TFEB) as a molecular link that connects extrinsic neuronal cues to intrinsic oligodendrocyte transcriptional programs, regulating central nervous system myelination. Using a TFEB epitope-tagged knock-in mouse model, we find that neurons sequester most of the TFEB protein in the cytoplasm of myelinating oligodendrocytes.

For some of the COVID-19 vaccines, the drug substances released to market were manufactured differently than those used in clinical trials. Manufacturing nucleoside-modified mRNA (modRNA) for commercial COVID-19 vaccines relies on RNA polymerase transcription of a plasmid DNA template. Previous studies identified high levels of plasmid DNA in vials of modRNA vaccines, suggesting that the removal of residual DNA template is problematic.
