Long non-coding RNA (LncRNA) telomerase RNA component (TERC) has telomerase-dependent and independent activity in numerous cancer types. The present study purposes to demonstrate the role of lncRNA TERC as a diagnostic serum biomarker in colorectal cancer (CRC) patients and the molecular mechanism of lncRNA TERC in inducing tumor in CRC cell lines. PCR array was performed to examine lncRNAs dysregulated in CRC. LncRNA TERC expression level was evaluated in 70 CRC patients and 35 control subjects using RT-qPCR. Then transfection was performed to build down-expression models of lncRNA TERC. ROC curve analysis was applied to assess the diagnostic value of serum LncRNA CRC. In addition, RT-qPCR was used to detect expression level of lncRNA TERC and β-catenin mRNA. Moreover, ELISA and Western blot were used to detect the level of β-catenin protein in sera of CRC patients and cell lines. The biological functions such as cell growth and migration of CRC cells were assessed using a wound healing assay. Cell cycle analysis and apoptosis analysis were performed using flow cytometry. The lncRNA TERC is overexpressed in the sera of CRC patients with high diagnostic and stage discrimination accuracy. Furthermore, lncRNA TERC expression was upregulated in CRC cell lines and lncRNA TERC silencing induced cell arrest and apoptosis and inhibited cell migration. Furthermore, inhibition of lncRNA TERC reduces β-catenin protein levels. The lncRNA TERC could be considered as an early stages CRC diagnostic biomarker with a good ability to discriminate between CRC stages. lncRNA TERC induces CRC by promoting cell migration and evading apoptosis by elevating the level of β-catenin protein.

Shogaol, a significant bioactive constituent of ginger, is present in several forms, including 4-, 6-, 8-, 10-, and 12-shogaol, with 6-shogaol identified as the most potent among them. Notably, 6-shogaol can be metabolized into 6-paradol, a compound that lacks pungency but retains biological activity. The primary focus of this review is to trace the diverse pharmacological effects of 6-shogaol, such as its anti-inflammatory, cardioprotective, neuroprotective, antioxidant, and anticancer properties, and to document the molecular mechanisms underlying these actions. 6-Shogaol’s broad spectrum of benefits makes it valuable in the health, food, and beverage industries, where its unique taste, high biocompatibility, and ability to alleviate or prevent various health issues are particularly advantageous. Its multiple mechanisms of action, including the modulation of oxidative stress and inflammation, contribute to its reputation as a promising natural compound. By highlighting the therapeutic potential of 6-shogaol, this review aims to provide a scientific foundation for its future development, clinical application, and incorporation into functional foods or pharmaceuticals, ultimately supporting its role as a versatile agent in promoting human health.

Ivermectin is a US Food and Drug Administration (FDA)-approved antiparasitic agent with antiviral and anti-inflammatory properties. Although recent studies reported the possible anti-inflammatory activity of ivermectin in respiratory injuries, its potential therapeutic effect on pulmonary fibrosis (PF) has not been investigated. This study aimed to explore the ability of ivermectin (0.6 mg/kg) to alleviate bleomycin-induced biochemical derangements and histological changes in an experimental PF rat model. This can provide the means to validate the clinical utility of ivermectin as a treatment option for idiopathic PF. The results showed that ivermectin mitigated the bleomycin-evoked pulmonary injury, as manifested by the reduced infiltration of inflammatory cells, as well as decreased the inflammation and fibrosis scores. Intriguingly, ivermectin decreased collagen fiber deposition and suppressed transforming growth factor-β1 (TGF-β1) and fibronectin protein expression, highlighting its anti-fibrotic activity. This study revealed for the first time that ivermectin can suppress the nucleotide-binding oligomerization domain (NOD)-like receptor family pyrin domain-containing protein 3 (NLRP3) inflammasome, as manifested by the reduced gene expression of NLRP3 and the apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), with a subsequent decline in the interleukin-1β (IL-1β) level. In addition, ivermectin inhibited the expression of intracellular nuclear factor-κB (NF-κB) and hypoxia-inducible factor-1α (HIF-1α) proteins along with lowering the oxidative stress and apoptotic markers. Altogether, this study revealed that ivermectin could ameliorate pulmonary inflammation and fibrosis induced by bleomycin. These beneficial effects were mediated, at least partly, via the downregulation of TGF-β1 and fibronectin, as well as the suppression of NLRP3 inflammasome through modulating the expression of HIF-1α and NF-κB.
