Aflatoxin B1 (AFB1) has been reported to synergize with hepatitis B virus (HBV) to induce development of hepatocellular carcinoma (HCC). Precise daily exposure to AFB1 and its contribution to liver injury have not been quantified and have even been disregarded due to lack of convenient detection, and the strong species specificity of HBV infection has restricted research on their synergistic harm. Hence, our objective was to investigate the molecular mechanisms by which AFB1 exacerbates HBV-related injury.

Background: N6-methyladenosine (mA)-mediated epitranscriptomic pathway has been shown to contribute to chemoresistance and radioresistance. Our previous work confirmed the defense of lycorine against tamoxifen resistance of breast cancer (BC) through targeting HOXD antisense growth-associated long non-coding RNA (HAGLR). Whereas, the precise regulation among them remains to be elucidated.

Initiation of chromosome replication is an essential stage of the bacterial cell cycle that is controlled by the DnaA protein. With the aim of developing novel antimicrobials, we have targeted the initiation of DNA replication, using antisense peptide nucleic acids (PNAs), directed against DnaA translation. A series of anti-DnaA PNA conjugated to lysine-rich bacterial penetrating peptides (PNA-BPPs) were designed to block DnaA translation.

The article provides a thorough and up-to-date analysis of the role that microRNAs (miRNAs) within the realm of cancer therapy, paying specific attention to their diagnostic, prognostic as well as therapeutic capabilities. The miRNAs (small non-coding RNAs) are the current major genes that regulate gene expression. They are a key factor in the genesis of cancer.

The CDKN2A gene, responsible for encoding the tumor suppressors p16(INK4A) and p14(ARF), is frequently inactivated in non-small cell lung cancer (NSCLC). Herein, an uncharacterized long non-coding RNA (lncRNA) (ENSG00000267053) on chromosome 19p13.12 was found to be overexpressed in NSCLC cells with an active, wild-type CDKN2A gene.
