Wnt Signaling Pathway in Tumor Biology.

Relapse and metastasis are the major challenges that stand in the way of cancer healing and survival, mainly attributed to cancer stem cells (CSCs). Their capabilities of self-renewal and tumorigenic potential leads to treatment resistance development. CSCs function through signaling pathways such as the Wnt/β-catenin cascade.

The Antioxidant, Antimicrobial, and Antitumor Proprieties of Flavonol-Rich Extracts from (Wild Garlic) Leaves: A Comparison of Conventional Maceration and Ultrasound-Assisted Extraction Techniques.

Despite the growing interest in using natural compounds for disease prevention and treatment, (wild garlic), known for its therapeutic properties, has not been extensively studied for its chemical composition and biological activities. Therefore, this study aims to explore the in vitro antioxidant, antibacterial, and antitumor activities of extracts according to their functional phytochemical profile, while assessing whether ultrasound-assisted extraction (UAE) enhances bioactive properties in comparison to conventional maceration (CM). Both extracts were characterized by spectrophotometric methods and LC-ESI+-MS.

Diagnostic Value of Nuclear Hybrid Imaging in Malignant Struma Ovarii: A Systematic Review of Case Reports.

Background: Struma ovarii is a rare tumor, a type of ovarian mature teratoma consisting over 50% of its mass in thyroid ectopic tissue; 5% to 10% of cases, as described in the literature, are malignant and well known as malignant struma ovarii or thyroid cancer from struma ovarii. Due to the limited number of malignant struma ovarii cases, the diagnostic and therapeutic approach of malignant struma ovarii lacks in standardization.

Methods: We performed a comprehensive search on the English language PubMed and Google Scholar.

In silico splicing analysis of the PMS2 gene: exploring alternative molecular mechanisms in PMS2-associated Lynch syndrome.

Lynch syndrome (LS) is one of the most common hereditary cancer syndrome in human populations, associated with germline variants in MLH1, MSH2/EPCAM, MSH6 and PMS2 genes. The advent of next generation sequencing has proven a significant impact in germline variant detection in the causative genes; however, a large proportion of patients with clinical criteria still receive uncertain or negative results. PMS2 is the least frequent reported gene, associated with up to 15% of LS cases with late-onset disease and low penetrance phenotype; however, the proportion of PMS2-LS cases is considered to be highly underestimated.

-Substituted AB-type phenothiazinyl porphyrins and their indium and zinc complexes photosensitising properties, cytotoxicity and phototoxicity on ovarian cancer cells.

New -substituted AB-type phenothiazinyl porphyrins and ferrocenylvinyl phenothiazinyl porphyrin were synthesised by Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions, respectively. The free porphyrins were further used in the synthesis of new indium(iii) or zinc(ii) porphyrin complexes. All porphyrins exhibit red fluorescence emission in solution, a property that remains unimpaired following internalisation in ovarian A2780 cancer cells, as evidenced by fluorescence microscopy images.

5-Azacytidine treatment inhibits the development of lung cancer models via epigenetic reprogramming and activation of cellular pathways with anti-tumor activity.

Children With Acute Lymphoblastic Leukemia in Romania: Results From a Decade-Long Single-Center Study.

Background: Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in children, with continuously improving survival rates. As few studies in Romania have analyzed ALL patients and disease characteristics or survival, we conducted a retrospective study on 158 patients diagnosed with ALL admitted to the Department of Pediatric Oncology and Hematology at the Emergency Hospital for Children, Cluj-Napoca, Romania, from January 2011 until April 2021. The most important objectives of the study are to establish full profiles of the patients and ALL, remission rates, relapses, and deaths, an epidemiology analysis to determine the incidence of ALL for comparison with the standard European population, and also to assess survival by the most important parameters, including minimal residual disease (MRD).

Macrophages as Potential Therapeutic Targets in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a heterogenous malignant hemopathy, and although new drugs have emerged recently, current treatment options still show limited efficacy. Therapy resistance remains a major concern due to its contribution to treatment failure, disease relapse, and increased mortality among patients. The underlying mechanisms of resistance to therapy are not fully understood, and it is crucial to address this challenge to improve therapy.
