Roles of probiotics against HPV through the gut-vaginal axis.

Human papillomavirus (HPV) is a sexually transmitted virus, whose persistent infection is the main reason for invasive cervical cancer (ICC), which is the fourth most common type of cancer in women, with more than 500 000 new cases every year. After infection, various alterations occur in the host, facilitating the virus's evasion of immune system clearance and promoting its proliferation. Oral probiotic consumption can influence the whole body's immunity, inflammatory reflection, neural, endocrine humoral, metabolic pathways and other organs by adjusting the components of gut microbiota (GM).

BZD9L1 Differentially Regulates Sirtuins in Liver-Derived Cells by Inducing Reactive Oxygen Species.

Growing evidence has highlighted that mitochondrial dysfunction contributes to drug-induced toxicities and leads to drug attrition and post-market withdrawals. The acetylation or deacetylation of mitochondrial proteins can affect mitochondrial functions as the cells adapt to various cellular stresses and other metabolic challenges. SIRTs act as critical deacetylases in modulating mitochondrial function in response to drug toxicity, oxidative stress, reactive oxygen species (ROS), and energy metabolism.

N-Doped Graphene Quantum Dots/Titanium Dioxide Nanocomposites: A Study of ROS-Forming Mechanisms, Cytotoxicity and Photodynamic Therapy.

Titanium dioxide nanoparticles (TiO NPs) have been proven to be potential candidates in cancer therapy, particularly photodynamic therapy (PDT). However, the application of TiO NPs is limited due to the fast recombination rate of the electron (e)/hole (h) pairs attributed to their broader bandgap energy. Thus, surface modification has been explored to shift the absorption edge to a longer wavelength with lower e/h recombination rates, thereby allowing penetration into deep-seated tumors.

Downregulation of Manic fringe impedes angiogenesis and cell migration of renal carcinoma.

Clear cell renal cell carcinoma (ccRCC) is a highly angiogenic cancer. Manic fringe (MFng) is elevated in ccRCC compared to the normal kidney. However, its role in ccRCC tumour angiogenesis remains elusive.

Nuclear and stromal expression of Manic fringe in renal cell carcinoma.

Renal cell carcinoma (RCC) is the most common type of kidney cancer and has the highest mortality rate among genitourinary cancers. Despite the advances in molecular targeted therapies to treat RCC, the inevitable emergence of resistance has delineated the need to uncover biomarkers to prospectively identify patient response to treatment and more accurately predict patient prognosis. Fringe is a fucose specific β1, 3N-acetylglucosaminyltransferase that modifies the Notch receptors.

BZD9L1 sirtuin inhibitor: Identification of key molecular targets and their biological functions in HCT 116 colorectal cancer cells.

Key Molecular Events in Cervical Cancer Development.

Cervical cancer is the fourth most common cancer among women. Infection by high-risk human papillomavirus (HPV) is the main aetiology for the development of cervical cancer. Infection by high-risk human papillomavirus (HPV) and the integration of the HPV genome into the host chromosome of cervical epithelial cells are key early events in the neoplastic progression of cervical lesions.

Epigenetics: The master control of endothelial cell fate in cancer.

The development of new blood vessels from pre-existing vasculature is called angiogenesis. The growth of tumors depends on a network of supplying vessels that provide them with oxygen and nutrients. Pro-angiogenic factors that are secreted by tumors will trigger the sprouting of nearby existing blood vessels towards themselves and therefore researchers have developed targeted therapy towards these pro-angiogenic proteins to inhibit angiogenesis.
