Modulation of Stemness and Differentiation Regulators by Valproic Acid in Medulloblastoma Neurospheres.

Cells

January 2025

Cancer and Neurobiology Laboratory, Experimental Research Center, Clinical Hospital (CPE-HCPA), Federal University of Rio Grande do Sul, Porto Alegre 90035-003, RS, Brazil.

Changes in epigenetic processes such as histone acetylation are proposed as key events influencing cancer cell function and the initiation and progression of pediatric brain tumors. Valproic acid (VPA) is an antiepileptic drug that acts partially by inhibiting histone deacetylases (HDACs) and could be repurposed as an epigenetic anticancer therapy. Here, we show that VPA reduced medulloblastoma (MB) cell viability and led to cell cycle arrest.

Serum α1-AT Levels and Molecular Analysis in Breast Cancer: An Experimental and Computational Study.

Diseases

December 2024

División de Genética, Centro de Investigación Biomédica de Occidente (CIBO), Instituto Mexicano del Seguro Social (IMSS), Sierra Mojada 800, Independencia Oriente, Guadalajara 44340, Jalisco, Mexico.

Background/objectives: Breast cancer (BC) is a heterogeneous disease with multifactorial origins, including environmental, genetic, and immunological factors. Inflammatory cytokines, such as alpha 1 antitrypsin (α1-AT), are increased in BC and affect physiological and pathological conditions. This study aimed to evaluate the serum levels of α1-AT and perform a computational analysis of in BC, as well as their association with molecular subtypes and clinical features.

Background: Zinc finger proteins (ZNFs) have been proved to play important roles in driving the progression of breast cancer (BC), one of the most common cancers among women. This study aimed to investigate the involvement of zinc-finger SWIM domain-containing protein 3 () in promoting BC cell progression by regulating lipid metabolism.

Methods: Differential expression of in BC was confirmed by comparing its expression in normal human mammary epithelial cells and BC cells.

Background: Peritumoral lidocaine infiltration prior to excision is associated with better survival in breast cancer (BC), which led us to hypothesize that innervation to the tumor affects its biology and patient survival. Activity-regulated cytoskeleton-associated protein (ARC) gene expression is known to be regulated by neuronal activity. Therefore, we studied the clinical relevance of ARC gene expression as a surrogate of neuronal activity in BC.

Background: Vascular endothelial growth factor-A (VEGFA) is a key inducer of angiogenesis, responsible for generating new blood vessels in the tumor microenvironment (TME) and facilitating metastasis. Notably, Avastin, which targets VEGFA, failed to demonstrate any significant benefit in clinical trials for breast cancer (BC). This study aimed to investigate the clinical relevance of gene expression in BC.

Extracellular vesicles-derived miR-21 as a biomarker for early diagnosis and tumor activity in breast cancer subtypes.

Biomark Res

January 2025

Laboratory of Cellular Therapy, Department of Medical and Surgical Sciences for Children and Adults, University Hospital of Modena, Modena, 41124, Italy.

Emerging evidence highlights the key role of microRNA (miR)-21 in cell-to-cell communication and tumorigenesis. However, limited knowledge exists on the levels and clinical meaning of miR-21 in extracellular vesicles (EVs) of patients with breast cancer (BC). We assessed EV-derived miR-21 levels in one hundred women: 30 with early BC (EBC), 30 with metastatic BC on treatment progression (MBC), 30 cancer survivors on follow-up (FU) and 10 healthy donors (HD) as age- and body mass index (BMI)-matched controls.

Effects of photobiomodulation in mitochondrial quantity, biogenesis and mitophagy-associated genes in breast cancer cells.

Lasers Med Sci

January 2025

Departamento de Biofísica e Biometria Instituto de Biologia Roberto Alcântara Gomes, Universidade do Estado do Rio de Janeiro, Avenida 28 de Setembro, 87, fundos, Vila Isabel, Rio de Janeiro, 20551030, Brazil.

In this article, we aim to evaluate the effects of photobiomodulation on mitochondria quantity, biogenesis, and mitophagy-associated genes in breast cancer (BC) cells. Both models were irradiated with a low-power infrared laser (880 nm, 150 mW) and amber LED (617 nm, 1500 mW), alone or simultaneously. We evaluated the mRNA expression of PINK1 and PGC-1α genes, and the mitochondrial number was assessed based on the ratio of mitochondrial DNA/genomic DNA (mtDNA/gDNA).

Background: Pain and subjective cognitive decline (SCD) are common sequala of breast cancer (BC) treatment. Adverse childhood experiences (ACEs) are associated with pain and adverse health outcomes in noncancer population. Sense of coherence (SOC) reflects the disposition that life is manageable and predictable.

BRCA functional domains associated with high risk of multiple primary tumors and domain-related sensitivity to olaparib: the Prometheus Study.

ESMO Open

January 2025

Department of Biomedicine, Neuroscience and Advanced Diagnostics (Bind.), Section of Medical Oncology, University of Palermo, Palermo, Italy.

Background: Germline pathogenic variants (gPVs) in the breast cancer susceptibility gene 1/2 (BRCA1/2) genes confer high-penetrance susceptibility to breast cancer (BC) and ovarian cancer (OC). Although most female BRCA carriers develop only a single BRCA-associated tumor in their lifetime, a smaller subpopulation is diagnosed with multiple primary tumors (MPTs). The genetic factors influencing this risk remain unclear.

Addressing the consequences of exposure to endocrine-disrupting chemicals (EDCs) demands thorough research and elucidation of the mechanism by which EDCs negatively impact women and lead to breast cancer (BC). Endocrine disruptors can affect major pathways through various means, including histone modifications, the erroneous expression of microRNA (miRNA), DNA methylation, and epigenetic modifications. However, it is still uncertain if the epigenetic modifications triggered by EDCs can help predict negative outcomes.

An update on promising and emerging protein kinase B/AKT inhibitors for breast cancer.

Expert Opin Pharmacother

January 2025

Division of New Drugs and Early Drug Development for Innovative Therapies, European Institute of Oncology, IRCCS, Milan, Italy.

Introduction: The PI3K pathway is crucial in breast cancer (BC), influencing cell survival, growth, and metabolism, with AKT playing a central role in treatment resistance. This pathway's involvement in breast carcinogenesis and its link to treatment resistance underscores the significance of targeting it in BC therapy. PI3K-pathway inhibitors offer new therapeutic avenues but bring challenges, especially due to toxicity issues that hinder their development.

Background: Not all breast cancer (BC) patients can benefit from neoadjuvant therapy (NAT). A poor response may result in patients missing the best opportunity for treatment, ultimately leading to a poor prognosis. Thus, to identify an effective predictor that can assess and predict patient response at early time points, we focused on circulating tumor DNA (ctDNA), which is a vital noninvasive liquid biopsy biomarker.

Purine-rich element binding protein alpha: a DNA/RNA binding protein with multiple roles in cancers.

Mol Med

January 2025

Nanjing Women and Children's Healthcare Hospital, Maternal and Child Health Institute, Women's Hospital of Nanjing Medical University, 123 Tianfei Alley, Mochou Road, Nanjing, China.

Proteins that bind to DNA/RNA are typically evolutionarily conserved with multiple regulatory functions in transcription initiation, mRNA translation, stability of RNAs, and RNA splicing. Therefore, dysregulation of DNA/RNA binding proteins such as purine-rich element binding protein alpha (PURα) disrupts signaling transduction and often leads to human diseases including cancer. PURα was initially recognized as a tumor suppressor in acute myeloid leukemia (AML) and prostate cancer (PC).

Breast cancer (BC) is classified based on the expression of histopathological markers, namely, estrogen receptor (ER), progesterone receptor (PgR), and human epidermal growth factor receptor 2 (HER2). Carcinomas with apocrine differentiation (CAD) are classified based on morphology. Androgen receptor (AR) is highly expressed in CAD; however, no study has comprehensively examined AR-related proteins in CAD.
