Notes

Gene duplications as well as phylogenomic discord underlie significant impulses associated with phenotypic evolution throughout gymnosperms.
Clinical studies suggest altered systemic vascular biology in cancer patients. We assessed expression patterns of endothelial activation- and vascular leakage-related genes in tumor as well as in tumor-free peripheral tissues from patients with and without ovarian cancer (OC).

Patients being scheduled for laparotomy for either gynecologic benign diagnosis (n=10) or for advanced-stage OC (n=22) were prospectively recruited to this observational study. Serum samples were taken preoperatively, and tissue samples were taken from peripheral abdominal wall musculature, tumor-free peritoneum and the tumor itself.

Patients in OC group received significantly more fluid per time intraoperatively (p=0.01). IL-8 and MCP-1/CCL2, VCAM-1 (CD 106) and ICAM-1 (CD 54) as well as Thrombomodulin were significantly increased in cancer patients' serum at baseline (p=0.03). Expression of distinct vascular leakage-related genes (Angiopoietin-1 (ANG-1), ANG-2, TIE2, VEGFR1, VEGFR2) was significantly altered in tumor tissue of OC patients (p=0.003), while in tumor-free peritoneal tissue, ANG-2/1 expression ratio was more than doubled in OC group (p=0.03). In peripheral musculature, particularly genes from the ANG/TIE axis were significantly changed in OC patients (p=0.005), suggesting a distinct vascular leakage-related genotype. Gene expression changes in OC patients were significantly associated with the postoperative fluid balance (p=0.03).

Altered expression of barrier dysfunction- and angiogenesis-associated genes from the ANG/TIE axis was detected not only in tumor but also in peripheral tissues of cancer patients. This may contribute to a systemic vascular leakage-related genotype.

The emergence of antibiotic tolerance was a tricky problem in the treatment of chronic Pseudomonas aeruginosa-infected cystic fibrosis and burn victims. The quorum sensing (QS) inhibitor may serve as a new tactic for the bacterial resistance by inhibiting the biofilm formation and the production of virulence factors. This study explored the potential of luteolin as a QS inhibitor against P. aeruginosa and the molecular mechanism involved.

Crystal violet staining, CLSM observation, and SEM analysis were carried out to assess the effect of luteolin on biofilm formation. The motility assays and the production of virulence factors were determined to evaluate the QS-inhibitory activity of luteolin. Acyl-homoserine lactone, RT-PCR, and molecular docking assays were conducted to explain its anti-QS mechanisms.

The biofilm formation, the production of virulence factors, and the motility of P. aeruginosa could be efficiently inhibited by luteolin. Luteolin could also attenuate the accumulation of the QS-signaling molecules N-(3-oxododecanoyl)-L-homoserine lactone (OdDHL) and N-butanoyl-L-homoserine lactone (BHL) (P<0.01) and downregulate the transcription levels of QS genes (lasR, lasI, rhlR, and rhlI) (P<0.01). NVL-655 Molecular docking analysis indicated that luteolin had a greater docking affinity with LasR regulator protein compared with OdDHL.

This study is important as it reports the molecular mechanisms involved in the anti-biofilm formation activity of luteolin against P. aeruginosa. This study also indicated that luteolin could be helpful when used for the treatment of clinical drug-resistant infections of P. aeruginosa.

Although the RNAi technique has been increasingly used for clinical trials, systemic siRNA delivery into targeted cells is still challenging. The barriers impeding siRNA therapeutics delivery and impacting the treatment outcome must overcome with negligible systemic toxicity for a desirable and successful delivery of siRNA to MDR cancer cells. Nano delivery strategies have been investigated for nanocarrier functionalization, cancer immunotherapy and cancer targeting. Lipid nanoparticles (LNPs), dynamic polyconjugates (DPC™), GalNAc-siRNA conjugates, exosome and RBC systems have shown potential for efficient delivery of siRNA to cancer cells. Delivery of siRNA to tumor cells, immune cells to regulate T cell functions for immunotherapy are promising approaches.
Evaluating the possible protective effect of thymol as an approach against 1,2 N,N-dimethylhydrazine and/or high-fat diet (HFD)-induced colon cancer.

Adult male Wistar rats were divided into 7 groups, namely a normal control group, colon cancer groups received DMH (40mg/kg i.p., twice weekly), 20% HFD and DMH/HFD, thymol (20mg/kg/day, p.o.), thymol/DMH and thymol/DMH/HFD (treatment of all groups continued for 16weeks).

Thymol significantly reduced the elevated serum levels of colon related tumor markers carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen (CEA) as well as the apoptotic marker, caspase-3 compared with the colon cancer group. In addition, it mitigated colonic tissue oxidative stress markers and inflammatory mediators. Moreover, the histopathological study revealed reduction of mucous secretion with elongated nuclei, frequent mitotic figures, focal nuclear stratification, mild interstitial edema, and markedly dilated congested blood vessels, aberrant crypt foci (ACF); adenoma with moderate to severe dysplasia of colon corrected by thymol treatment.

The administration of thymol had a promising preclinical protective efficacy and could be considered as a new strategy for the prophylaxis from colon cancer in clinical practices.
