A new nucleus-localized singlet oxygen generator was designed and synthesized. Its capability to label nucleus-localized biomolecules through spatially-restricted oxidation under visible light was validated using fluorescence confocal microscopy. Western blot and RT-qPCR were performed to verify the desirable spatial resolution through enriching chromatin-associated RNAs and proteins.

Long non-coding RNA CAR10 promotes angiogenesis of lung adenocarcinoma by mediating nuclear LDHA to epigenetically regulate VEGFA/C.

Commun Biol

The First Department of Thoracic Surgery, Hunan Cancer Hospital and the affiliated Cancer Hospital of Xiangya School of Medicine, Central South University, Changsha, PR China.

Angiogenesis is a significant character of lung adenocarcinoma (LUAD) and is an important reason leading to high mortality rates of LUAD patients. However, the molecular mechanisms of lncRNAs regulating the angiogenesis in LUAD have not been fully elucidated. Here we show lncRNA chromatin-associated RNA 10 (CAR10) was upregulated in the tumor tissue of patients with LUAD and enhanced tumor metastasis.

Histone proteoforms, often presenting multiple co-occurring post-translational modifications (PTMs), are central to chromatin regulation and gene expression. A proteoform is a specific form of a protein that includes variations arising from genetic changes, alternative RNA splicing, proteolytic processing, and PTMs. Genomic context-dependent histone proteoforms define the histone code, influencing cellular phenotype by dictating interactions with DNA and chromatin-associated proteins.

Contribution of the paternal histone epigenome to the preimplantation embryo.

Front Cell Dev Biol

Department of Animal Science, Texas A&M University, College Station, TX, United States.

The paternal germline contains a plethora of information that extends beyond DNA. Packaged within the sperm cell is a wealth of epigenetic information, including DNA methylation, small RNAs, and chromatin associated histone proteins and their covalently attached post-translational modifications. Paternal chromatin is particularly unique, as during the process of spermatogenesis, nearly all histones are evicted from the genome with only a small percentage retained in the mature sperm cell.

Many RNAs associate with chromatin, either directly or indirectly. Several technologies for mapping regions where RNAs interact across the genome have been developed to investigate the function of these RNAs. Obtaining information on the proteins involved in these RNA-chromatin interactions is critical for further analysis.

Hypoxia-induced alternative splicing (AS) regulates tumor progression and metastasis. Little is known about how such AS is controlled and whether higher-order genome and nuclear domain (ND) organizations dictate these processes. We observe that hypoxia-responsive alternatively spliced genes position near nuclear speckle (NS), the ND that enhances splicing efficiency.
