RIOK1: A Novel Oncogenic Driver in Hepatocellular Carcinoma.
Cancer Med
February 2025
Centre for Medical Research, Ningbo No.2 Hospital, Ningbo, China.
Background: Hepatocellular carcinoma (HCC) is one of the most common and highly lethal cancers worldwide. RIO kinase 1 (RIOK1), a protein kinase/ATPase that plays a key role in regulating translation and ribosome assembly, is associated with a variety of malignant tumors. However, the role of RIOK1 in HCC remains largely unknown.

Background: Histone H2B is highly expressed in many types of cancers and is involved in cancer development. H2B clustered histone 9 (H2BC9), a member of the H2B family, plays critical roles in gene expression regulation, chromosome structure, DNA repair stability, and cell cycle regulation. However, the diagnostic and prognostic value of H2BC9 in head and neck squamous cell carcinoma (HNSCC) remains unclear.

Glioblastoma (GBM) is the most common malignant primary brain cancer with poor prognosis due to the resistant to current treatments, including the first-line drug temozolomide (TMZ). Accordingly, it is urgent to clarify the mechanism of chemotherapeutic resistance to improve the survival rate of patients. In the present study, by integrating comprehensive non-coding RNA-seq data from multiple cohorts of GBM patients, we identified that a series of miRNAs are frequently downregulated in GBM patients compared with the control samples.

Jiangsu Province Key Laboratory of Oral Diseases, Nanjing, Jiangsu Province, China.
Plp1-lineage Schwann cells (SCs) of peripheral nerve play a critical role in vascular remodeling and osteogenic differentiation during the early stage of bone healing, and the abnormal plasticity of SCs would jeopardize the bone regeneration. However, how Plp1-lineage cells respond to injury and initiate the vascularized osteogenesis remains incompletely understood. Here, by employing single-cell transcriptional profiling combined with lineage-specific tracing models, we uncover that Plp1-lineage cells undergoing injury-induced glia-to-MSCs transition contributed to osteogenesis and revascularization in the initial stage of bone injury.

Institute of Chemical Biology and Fundamental Medicine, Siberian Branch of the Russian Academy of Sciences, Novosibirsk, 630090, Russia.
Taking into account involvement of the RNA-binding proteins in regulation of activity of poly(ADP-ribose) polymerase 1 (PARP1), a key factor of DNA repair, the effect of the intrinsically disordered protein Sam68 (Src-associated substrate during mitosis of 68 kDa) on catalytic activity of this enzyme was studied. Plasmid containing coding sequence of the Sam68 protein was obtained. Using the obtained construct, conditions for the Sam68 expression in cells were optimized and procedure for protein purification was developed.
