Primary melanoma of female urethra: A case diagnosed in Ouagadougou
We report a case of primary melanoma of a female urethra diagnosed at a non-metastatic stage in a 48-year-old patient with a history of breast carcinoma treated with radiotherapy and hormone therapy. The patient was consulting for dysuria, hematuria, and perineal pain. The clinical examination found a prolapsed and black mass, developed at the expense of the urethra and located at the anterosuperior part of the vulva. The mass biopsy revealed a proliferation of fusiform and globular cells loaded with black pigment expressing the anti-HMB 45 and PS 100 antibodies. The extension assessment showed an absence of secondary loca...

Targeted proteomic quantitation of NRF2 signaling and predictive biomarkers in HNSCC
Mol Cell Proteomics. 2023 Sep 14:100647. doi: 10.1016/j.mcpro.2023.100647. Online ahead of print.ABSTRACTThe NFE2L2(NRF2) oncogene and transcription factor drives a gene expression program that promotes cancer progression, metabolic reprogramming, immune evasion and chemoradiation resistance. Patient stratification by NRF2 activity may guide treatment decisions to improve outcome. Here, we developed a mass spectrometry (MS)-based targeted proteomics assay based on internal standard triggered parallel reaction monitoring (IS-PRM) to quantify 69 NRF2 pathway components and targets, as well as 21 proteins of broad clinical si...

MicroRNAs and their vital role in apoptosis in hepatocellular carcinoma: miRNA-based diagnostic and treatment methods
Gene. 2023 Sep 14;888:147803. doi: 10.1016/j.gene.2023.147803. Online ahead of print.ABSTRACTHepatocellular carcinoma (HCC) is one of the most prevalent malignancies with high invasive and metastatic capability. Although significant advances have been made in the treatment of HCC, the overall survival rate of patients is still low. It is essential to explore accurate biomarkers for early diagnosis and prognosis along with therapeutic procedures to increase the survival rate of these patients. Anticancer therapies can contribute to induce apoptosis for the elimination of cancerous cells. However, dysregulated apoptosis and ...

Aflatoxin B1 triggers apoptosis in rabbit hepatocytes via mediating oxidative stress and switching on the mitochondrial apoptosis pathway
Ecotoxicol Environ Saf. 2023 Sep 14;264:115478. doi: 10.1016/j.ecoenv.2023.115478. Online ahead of print.ABSTRACTAflatoxin B1 (AFB1) is considered the most toxic carcinogenic compound, and exposure to AFB1 is highly associated with hepatocellular carcinoma. The aim of this study was to investigate the effects of different doses of AFB1 on growth performance and the liver of rabbits, as well as explore its underlying mechanisms. A total of eighty 30-day-old meat rabbits were randomly divided into four treatments. The control group was fed a pollution-free diet, while the AFL, AFM, and AFH groups were fed contaminated diets ...

Intratumoral Bacteria as Mediators of Cancer Immunotherapy Response
Cancer Res. 2023 Sep 15;83(18):2985-2986. doi: 10.1158/0008-5472.CAN-23-1857.ABSTRACTMultiple lines of evidence spanning from animal models to human clinical trials indicate that the microbiome influences cancer immunotherapy response. Whereas initial studies focused exclusively on the gastrointestinal (gut) microbiota-tumor axis, more recent studies have examined the possibility that bacteria located within tumor cells or within the tumor microenvironment mediate cancer treatment response. Strikingly, this phenomenon has been demonstrated in cancers that arise in anatomic locations that are traditionally thought to be dev...

Epiberberine suppresses the metastasis of head and neck squamous cell carcinoma cells by regulating the MMP-13 and JNK pathway
In conclusion, the present study demonstrates that epiberberine suppresses cell migration and invasion by regulating the JNK pathway and MMP-13. These results suggest that epiberberine could be a potential antimetastatic agent in HNSCC cells.PMID:37710409 | DOI:10.1111/jcmm.17954

Podophyllotoxin reduces the aggressiveness of human oral squamous cell carcinoma through myeloid cell leukemia ‑1
Int J Mol Med. 2023 Nov;52(5):103. doi: 10.3892/ijmm.2023.5306. Epub 2023 Sep 15.ABSTRACTPodophyllotoxin (PPT), which is derived from the podophyllum plant, exhibits marked cytotoxic effects against cancer cells; however, the precise molecular mechanism underlying its activity against human oral squamous cell carcinoma (OSCC) has not been elucidated. In the present study, the mechanism by which PPT induced cytotoxicity in two OSCC cell lines, HSC3 and HSC4, was determined. The effects of PPT on cytotoxicity in HSC3 and HSC4 cells were analyzed using Annexin V/PI double staining, Sub‑G1 analysis, soft agar assays, western...
