Roles and Mechanisms of Ferroptosis in Sorafenib Resistance for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the most prevalent malignant tumor, characterized by a poor prognosis. In recent decades, both the incidence and mortality rates of HCC have risen sharply. Sorafenib has emerged as the first conventional drug approved by the US Food and Drug Administration for first-line treatment in advanced HCC patients due to its favorable safety profile.

Prognostic value of CMTM6 protein in hepatocellular carcinoma involving the regulation of the immune microenvironment.

There have been notable irregularities in CMTM6 expression observed in hepatocellular carcinoma (HCC), with an evident correlation between CMTM6 dysregulation and patient prognosis. The cell cycle progression came to a halt at the G2/M phase. In-depth RNA-sequencing analysis of CMTM6 knockdown Hep3B cells revealed that the most prominent effect of CMTM6 perturbation was on the expression of CXCL8, a chemokine involved in immune responses, particularly through the interleukin-17F (IL-17F) signaling pathway.

Potential and application of abortive transcripts as a novel molecular marker of cancers.

Abortive transcript (AT) is a 2-19 nt long non-coding RNA that is produced in the abortive initiation stage. Abortive initiation was found to be closely related to RNA polymerase through experiments. Therefore, the distribution of AT length and the scale of abortive initiation are correlated to the promoter, discriminator, and transcription initiation sequence, and can be affected by transcription elongation factors.

Non-linear association and benchmark dose of blood pressure on carotid artery intima-media thickening in a general population of southern China.

Roles of Myc-associated zinc finger protein in malignant tumors.

As an important transcription factor that is widely expressed in most tissues of the human body, Myc-associated zinc finger protein (MAZ) has been reported highly expressed in many malignant tumors and thought to be a promising therapeutic target for cancer treatment.
