Altered vaginal cervical microbiota diversity contributes to HPV-induced cervical cancer inflammation regulation.

Background: Cancer has surpassed infectious diseases and heart ailments, taking the top spot in the disease hierarchy. Cervical cancer is a significant concern for women due to high incidence and mortality rates, linked to the human papillomavirus (HPV). HPV infection leads to precancerous lesions progressing to cervical cancer.

Effects of peripheral blood neutrophil/lymphocyte ratio levels and their changes on the prognosis of patients with early cervical cancer.

Although some studies have reported on the levels and clinical significance of peripheral blood neutrophil/lymphocyte ratio (NLR) in cervical cancer, the role of NLR levels and their changes preoperatively and postoperatively in early cervical cancer remain unclear. Our analyses explored the preoperative and postoperative NLR in 203 patients with stage I-IIA cervical cancer and evaluated the relationship between NLR changes, clinicopathological characteristics, and patient prognosis. The cut-off preoperative and postoperative NLR values were determined using receiver operating characteristic curve analysis.

Exploring the Mechanism of against Ovarian Cancer based on Network Pharmacology and the Influence of Luteolin on the PI3K/AKT Pathway.

Background: Ovarian cancer (OC) is a commonly diagnosed female cancer around the world. The Chinese herbal medicine has an anti-cancer effect. However, there is no relevant report on whether is effective in treating OC, and the corresponding mechanism is also unknown.

Bruceine D and afatinib combination inhibits ovarian cancer cells proliferation and migration through DNA damage repair and EGFR pathway.

Owing to the high rates of relapse and migration, ovarian cancer (OC) has been recognized as the most lethal gynecological malignancy worldwide. The activity of the epidermal growth factor receptor (EGFR) signaling pathway is frequently associated with OC cell proliferation and migration. Despite this knowledge, inhibition of EGFR signaling in OC patients failed to achieve satisfactory therapeutic effects.

G-quadruplex stabilizer Tetra-Pt(bpy) disrupts telomere maintenance and impairs FAK-mediated migration of telomerase-positive cells.

G-quadruplex regulates a wide spectrum of biological processes, including telomere maintenance, DNA replication and transcription. The development of small molecules to selectively target G-quadruplex and their application remain hotspots in cancer therapy. Here, we explored the biological effect of G-quadruplexes stabilizer Tetra-Pt(bpy) in telomerase-positive cancer cells.

A chalcone-syringaldehyde hybrid inhibits triple-negative breast cancer cell proliferation and migration by inhibiting CKAP2-mediated FAK and STAT3 phosphorylation.

Background: Although triple-negative breast cancer (TNBC) accounts for only 15% of breast cancer cases, it is associated with a high relapse rate and poor outcome after standard treatment. Currently, the effective drugs and treatment strategies for TNBC remain limited, and thus, developing effective treatments for TNBC is pressing. Several studies have demonstrated that both chalcone and syringaldehyde have anticancer effect, but their potential anti-TNBC bioactivity are still unknown.

Risk factors associated with the persistence of human papillomavirus after cervical excision in patients with high-grade squamous intra-epithelial neoplasia.

Objective: To evaluate risk factors associated with the persistence of human papillomavirus (HPV) after cervical excision in patients with high-grade squamous intra-epithelial neoplasia (HSIL).

Methods: A retrospective cohort study enrolled 550 patients who underwent cervical excision for HSIL between January 2015 and January 2018. The effects of various factors were assessed using univariate and multi-variate analyses.

The different biological effects of TMPyP4 and cisplatin in the inflammatory microenvironment of osteosarcoma are attributed to G-quadruplex.

Objective: Osteosarcoma (OS) is characterized by high levels of the tumour-associated inflammatory microenvironment. Moreover, in approximately 60% of OS, telomere length is maintained by alternative lengthening of telomeres (ALT) pathway. Whether the ALT pathway can be exploited for OS therapeutic treatment and how the OS inflammatory microenvironment influences the anti-cancer drug effect remains unknown.

HO enhances the anticancer activity of TMPyP4 by ROS-mediated mitochondrial dysfunction and DNA damage.

Cancer is one of the diseases that threatens human health and is a leading cause of mortality worldwide. High levels of reactive oxygen species (ROS) have been observed in cancer tissues compared with normal tissues in vivo, and it is not yet known how this influences chemotherapeutic drug action. Cationic porphyrin 5,10,15,20-tetra-(N-methyl-4-pyridyl) porphyrin (TMPyP4) is a photosensitizer used in photodynamic therapy (PDT) and a telomerase inhibitor used in the treatment of telomerase-positive cancer.
