Background: Increasing evidences have indicated the association of non-coding RNAs with the progression of lumbar disc degeneration (LDD), but the role of lncRNA ZFAS1 in LDD remains undefined. Therefore, this study was designed to determine the predictive value of lncRNA ZFAS1 in patients with LDD.
Methods: A total of 80 patients with LDD confirmed and treated in the Gansu Provincial Hospital from May 2018 to May 2020 were enrolled into the patient group, and 50 healthy controls who concurrently underwent physical examination in our hospital were enrolled into the control group. The expression and diagnostic value of serum lncRNA ZFAS1 in the two groups were determined. The expression of lncRNA ZFAS1 was compared between the two groups before and one month after therapy, and the associations of lncRNA ZFAS1 with inflammatory factors were analyzed. In addition, logistic regression was carried out to analyze risk factors for the prognosis of patients, and corresponding curves about prediction were drawn.
Results: The patient group showed a notably higher lncRNA ZFAS1 level than the control group (P<0.001), and the area under the receiver operating characteristic (ROC) of lncRNA ZFAS1 in diagnosing LDD was 0.807. In addition, after therapy, the patient group showed a remarkable decrease in serum lncRNA ZFAS1 (P<0.01). Serum lncRNA ZFAS1 was positively correlated with serum TNF-α, IL-6 and IL-1β in patients (all P<0.05). Moreover, serum lncRNA ZFAS1 in the good efficacy group was notably lower than that in the general efficacy group (P<0.01). Age and lncRNA ZFAS1 expression before therapy were independent risk factors for patients' prognosis (both P<0.05).
Conclusion: LncRNA ZFAS1 is highly expressed in patients with LDD and is a potential prognostic indicator for LDD.

High levels of the N7 methylguanosine (m7G) methyltransferase WD repeat domain 4 (WDR4) are associated with the progression of multiple tumors, including head and neck squamous cell carcinoma. Laryngeal cancer (LC) is the second most common malignant tumor of the head and neck. However, the role of WDR4 in LC remains unclear.

Objective: Long non-coding RNA (lncRNA) has been playing an increasingly significant role in neuropathic pain (NP). This study aimed to investigate the clinical significance and mechanism of LncRNA ZNFX1 antisense RNA 1 (ZFAS1) in NP.
Methods: 92 patients with NP and 85 healthy controls were enrolled, and a rat NP model was constructed by chronic constrictive injury (CCI).

Tooth development is an intricate process that encompasses cellular activities, molecular signaling pathways, and gene expression patterns. Disruptions in any of the processes can lead to structural anomalies, impairments in function, and increased vulnerability to oral disorders. Alveolar resorption, which refers to the pathological loss of alveolar bone around teeth, poses a substantial clinical problem in periodontal disorders such as periodontitis.

Objective: To probe the involvement of long noncoding RNA zinc finger antisense 1 (ZFAS1)/microRNA (miR)-186-5p axis in inhibiting oxidative stress in myocardial ischemia-reperfusion injury (MIRI) by targeting B-cell translocation gene 2 (BTG2).
Methods: The MIRI mice model was established by ligating the left anterior descending branch of the left coronary artery in C57BL/6 mice. The in vitro MIRI model was constructed by hypoxia and reoxygenation of HL-1 cardiomyocytes.

Article Synopsis
- ZFAS1 is identified as an oncogenic long noncoding RNA that is upregulated in hepatocellular carcinoma (HCC) and is associated with poor patient outcomes.
- Inhibition of ZFAS1 leads to reduced HCC cell growth and promotes ferroptosis, while its overexpression has the opposite effect.
- The study reveals a mechanism where ZFAS1 interacts with miR-150 to regulate AIFM2, a key protector against ferroptosis, highlighting a potential therapeutic target for HCC treatment.
