MicroRNAs (miRs) play important roles in tumor progression. miR-936 has been reported to suppress cell invasion and proliferation of glioma and non-small cell lung cancer. Nevertheless, the function of miR-936 in laryngeal squamous cell carcinoma (LSCC) remains undiscovered. Hence, our study was to investigate the role of miR-936 in LSCC. In our present research, we have testified that miR-936 was substantially downregulated in LSCC tissues compared with adjacent normal tissues. Furthermore, miR-936 could inhibit proliferation, migration and invasion, and improve the sensitivity to doxorubicin and cisplatin of LSCC cells. Additionally, luciferase reporter assays were performed to confirm that GPR78 was a novel target of miR-936, and the protein expression of GPR78 was obviously inhibited by miR-936 in LSCC cells. In summary, our study indicates that the miR-936/GPR78 axis could be both a diagnostic marker and a therapeutic target for LSCC.

Low miR-936-mediated upregulation of Pim-3 drives sorafenib resistance in liver cancer through ferroptosis inhibition by activating the ANKRD18A/Src/NRF2 pathway.

Article Synopsis
- Sorafenib, a common treatment for advanced liver cancer, faces limitations due to the development of drug resistance, which poses challenges in understanding and overcoming this resistance.
- The study involved observing liver cancer patients on sorafenib, creating resistant cell lines, and conducting various molecular assays to explore the mechanisms of resistance.
- Results revealed that high levels of Pim-3 predict poor outcomes for patients and are linked to resistance; this is influenced by reduced levels of microRNA-936, which normally suppresses Pim-3 expression and its associated pro-resistance pathways.
Knockdown of circ_0076305 decreases the paclitaxel resistance of non-small cell lung cancer cells by regulating TMPRSS4 via miR-936.

Background: Paclitaxel (PTX) is a commonly used as a chemotherapeutic drug for non-small cell lung cancer (NSCLC). Exploring the underlying mechanism of PTX resistance is of great significance for NSCLC treatment.
Methods: The expression levels of RNA and protein were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot assays.

Article Synopsis
- Hepatocellular carcinoma (HCC) is a severe cancer with a high risk of spreading and limited treatment options.
- A newly identified circular RNA, circZCCHC2, is found to be elevated in HCC and correlates with poor patient outcomes.
- CircZCCHC2 promotes cancer cell growth and metastasis by regulating the expression of BTBD7 through interaction with miR-936, impacting the Rho/ROCK2 signaling pathway.

Background: Studies have shown that fine particulate matter (PM) remains a significant problem in developing countries and plays a critical role in the onset and progression of respiratory illnesses. Circular RNAs (circRNAs) are involved in many pathophysiological processes,but their relationship to PM pollution is largely unexplored.
Objectives: To elucidate the functional role of hsa_circ_0000992 in PM-induced inflammation in a human bronchial epithelial cell line (16HBE) and to clarify whether the competing endogenous RNA (ceRNA) mechanism is involved in the interrelationships between hsa_circ_0000992 and hsa-miR-936 and the inflammatory signaling pathways.

Circular RNAs (circRNAs) have been reported to be implicated in the tumorigenesis and progression of ovarian cancer. Here, the study was designed to explore the activity of human circ_0021573 in ovarian cancer pathogenesis and its regulation through the competing endogenous RNA (ceRNA) crosstalk. Circ_0021573, microRNA (miR)- 936, and cullin 4B (CUL4B) were quantified by qRT-PCR and western blot.
