Breast cancer's complexity and heterogeneity continue to present significant challenges in its treatment and management. Emerging research has underscored the pivotal role of microRNAs (miRNAs) in breast cancer pathogenesis, acting as crucial regulators of gene expression. This review delivers an in-depth analysis of miRNAs, highlighting their dual functions as both oncogenes and tumor suppressors, and detailing their impact on key biological processes, including cell proliferation, apoptosis, and metastasis.

Article Synopsis
  • Oral cancer (OC) is a major health concern worldwide, with current treatments like surgery, radiation, and chemotherapy often leading to severe side effects and risk of recurrence.
  • Natural compounds from plants, such as quercetin and curcumin, are gaining traction for their potential to fight OC with less toxicity and effective targeting of cancer cell growth.
  • Recent research highlights the importance of microRNAs (miRNAs) in OC, suggesting that using natural products to regulate these miRNAs could be a promising approach for improving treatment outcomes.

Article Synopsis
  • The study identifies OCT2 as the primary transporter responsible for cisplatin accumulation in kidney cells, leading to nephrotoxicity; Doxepin (DOX) is noted for its ability to inhibit OCT2.* -
  • Rats were divided into six groups to investigate DOX's protective effects against cisplatin-induced kidney damage, showing that DOX improved kidney health by reducing inflammation and oxidative stress markers.* -
  • Results indicated that DOX not only decreased OCT2 expression and apoptotic markers but also altered the PI3K/Akt signaling pathway, highlighting its renoprotective qualities against cisplatin toxicity.*

Asthma is a diverse inflammatory illness affecting the respiratory passages, leading to breathing challenges, bouts of coughing and wheezing, and, in severe instances, significant deterioration in quality of life. Epigenetic regulation, which involves the control of gene expression through processes such as post-transcriptional modulation of microRNAs (miRNAs), plays a role in the evolution of various asthma subtypes. In immune-mediated diseases, miRNAs play a regulatory role in the behavior of cells that form the airway structure and those responsible for defense mechanisms in the bronchi and lungs.

Asthma is a chronic non-communicable respiratory disease that is characterized by airway inflammation and hyperreactivity. Defective functions of airway smooth muscle and dysregulated signaling pathways play a crucial role in the pathogenesis of asthma. Anti-inflammatories and targeted therapy are mainly used for the treatment of asthma.

Aim: Cardiac fibrosis is characterized by excessive accumulation of fibrous tissue, particularly collagens, in the myocardium. Accumulated fibrous tissue renders myocardium stiffer and reduces its contractility. Empagliflozin is an oral hypoglycemic agent with extra-diabetic functional profile toward maintaining cardiac functions.

Oral cancer (OC) is the predominant type originating in the head and neck region. The incidence of OC is mostly associated with behavioral risk factors, including tobacco smoking and excessive alcohol intake. Additionally, there is a lower but still significant association with viral infections such as human papillomaviruses and Epstein-Barr viruses.

Background: This work aimed to prepare niosomal formulations of an anticancer agent [mefenamic acid (MEF)] to enhance its cancer targeting. I was utilized as a radiolabeling isotope to study the radio-kinetics of MEF niosomes.

Methods: niosomal formulations were prepared by the ether injection method and assessed for entrapment efficiency (EE%), zeta potential (ZP), polydispersity index (PDI) and particle size (PS).

Oxidative stress and epigenetic alterations, including the overexpression of all class I and II histone deacetylases (HDACs), particularly HDAC2 and HDAC4, have been identified as key molecular mechanisms driving pulmonary fibrosis. Treatment with piceatannol (PIC) or vitamin D (Vit D) has previously exhibited mitigating impacts in pulmonary fibrosis models. The present study investigated the effects of PIC, Vit D, or a combination (PIC-Vit D) on the expression of HDAC2, HDAC4, and transforming growth factor-beta (TGF-β) in the lungs; the phosphatidylinositide-3-kinase (PI3K)/AKT signaling pathway; and the antioxidant status of the lungs.

Article Synopsis
  • Adrenocortical carcinoma (ACC) is a rare but aggressive cancer with high mortality rates, and while research has improved understanding, challenges in diagnosis and prognosis remain.
  • MicroRNAs (miRNAs) are significant in cancer development and may serve as diagnostic and prognostic biomarkers in ACC, as well as potential treatment targets.
  • Despite advancements in knowledge and treatment options, the prognosis for patients with advanced ACC remains poor, highlighting the need for further research in miRNA applications.

This study aimed to formulate a pharmaceutical dosage form containing omeprazole (OMP) and curcumin (CURC) to treat experimental peptic ulcers. OMP and CURC were preliminarily complexed with hydroxypropyl-β-cyclodextrin for enhancing their solubilization. After that, the combined complex (CURC/OMP) was loaded to alginate beads to sustain their release and then coated with chitosan.
