Clinical significance of vit D and AMH and its correlation with polycystic ovarian parameters in obese and non-obese Egyptian women.

Women of reproductive age are frequently affected by the heterogeneous endocrine-metabolic conditions recognized as polycystic ovarian syndrome (PCOS). Moreover, FSH (Follicle-stimulating hormone), steroidogenesis, and LH (Luteinizing Hormone) are suppressed by the anti-Mullerian hormone, a good indicator of ovarian reserve, that is generated from granulosa cells. In the past ten years, vitamin D (VD) has attracted and maintained great interest in human health and biomedical research, particularly those about female reproductive-metabolic problems.

Possible role of miRNAs in pheochromocytoma pathology - Signaling pathways interaction.

Pheochromocytoma (PCC) is a type of neuroendocrine tumor that originates from adrenal medulla or extra-adrenal chromaffin cells and results in the production of catecholamine. Paroxysmal hypertension and cardiovascular crises were among the clinical signs experienced by people with PCC. Five-year survival of advanced-stage PCC is just around 40% despite the identification of various molecular-level fundamentals implicated in these pathogenic pathways.

From diagnosis to resistance: a symphony of miRNAs in pheochromocytoma progression and treatment response.

Pheochromocytoma (PCC) is a neuroendocrine tumor that produces and secretes catecholamine from either the adrenal medulla or extra-adrenal locations. MicroRNAs (miRNAs, miR) can be used as biomarkers to detect cancer or the return of a previously treated disease. Blood-borne miRNAs might be envisioned as noninvasive markers of malignancy or prognosis, and new studies demonstrate that microRNAs are released in body fluids as well as tissues.

Decoding the role of miRNAs in multiple myeloma pathogenesis: A focus on signaling pathways.

Multiple myeloma (MM) is a cancer of plasma cells that has been extensively studied in recent years, with researchers increasingly focusing on the role of microRNAs (miRNAs) in regulating gene expression in MM. Several non-coding RNAs have been demonstrated to regulate MM pathogenesis signaling pathways. These pathways might regulate MM development, apoptosis, progression, and therapeutic outcomes.

miRNAs driving diagnosis, progression, and drug resistance in multiple myeloma.

Multiple myeloma (MM) is a tumor of transformed plasma cells. It's the second most common hematologic cancer after non-Hodgkin lymphoma. MM is a complex disease with many different risk factors, including ethnicity, race, and epigenetics.

Histone deacetylase (HDAC) inhibitors have good contributions in cancer management. To introduce new active HDAC inhibitors. Design and synthesis of 16 thiouracil derivatives with deep biological and computational investigation.

The role of miRNAs in laryngeal cancer pathogenesis and therapeutic resistance - A focus on signaling pathways interplay.

Laryngeal cancer (LC)is the malignancy of the larynx (voice box). The majority of LC are squamous cell carcinomas. Many risk factors were reported to be associated with LC as tobacco use, obesity, alcohol intake, human papillomavirus (HPV) infection, and asbestos exposure.

New indole derivatives as multitarget anti-Alzheimer's agents: synthesis, biological evaluation and molecular dynamics.

Alzheimer's disease is a neurological disorder that causes brain cells to shrink and die. Thirteen novel 'oxathiolanyl', 'pyrazolyl' and 'pyrimidinyl' indole derivatives were designed and synthesized as anti-Alzheimer's disease treatment. enzyme assay was performed against both AChE and BChE enzymes.

A spotlight on the interplay of signaling pathways and the role of miRNAs in osteosarcoma pathogenesis and therapeutic resistance.

Osteosarcoma (OS) is one of the most common bone cancers that constantly affects children, teenagers, and young adults. Numerous epigenetic elements, such as miRNAs, have been shown to influence OS features like progression, initiation, angiogenesis, and treatment resistance. The expression of numerous genes implicated in OS pathogenesis might be regulated by miRNAs.

Significance of miRNAs on the thyroid cancer progression and resistance to treatment with special attention to the role of cross-talk between signaling pathways.

Thyroid cancer (TC) is the most prevalent endocrine malignant tumor. It has many types, the Papillary thyroid cancer (PTC)(most common and follicular thyroid carcinoma (FTC). Several risk factors have been associated with TC radiation exposure, autoimmunity, and genetics.

Megalin, a multi-ligand endocytic receptor, and its participation in renal function and diseases: A review.

The endocytosis mechanism is a complicated system that is essential for cell signaling and survival. Megalin, a membrane-associated endocytic receptor, and its related proteins such as cubilin, the neonatal Fc receptor for IgG, and NaPi-IIa are important in receptors-mediated endocytosis. Physiologically, megalin uptakes plasma vitamins and proteins from primary urine, preventing their loss.

Synthesis, biological evaluation, and studies of new CDK2 inhibitors based on pyrazolo[3,4-]pyrimidine and pyrazolo[4,3-][1,2,4]triazolo[1,5-]pyrimidine scaffold with apoptotic activity.

Cyclin-dependent kinase inhibition is considered a promising target for cancer treatment for its crucial role in cell cycle regulation. Pyrazolo pyrimidine derivatives were well established for their antitumor activity via CDK2 inhibition. In this research, new series of pyrazolopyrimidine derivatives () was designed and synthesised as novel CDK2 inhibitors.

Pioglitazone ameliorates high fat diet-induced hypertension and induces catechol o-methyl transferase expression in rats.

Our study aimed to investigate the effect of pioglitazone (PIO) on the obesity-associated metabolic effects and whether this effect is associated with modulation of catechol O-methyl transferase (COMT) expression in the high fat diet (HFD) induced obese rats. Male Wistar rats fed HFD were used to evaluate the effect of PIO on obesity-associated hypertension and the expression of COMT. The HFD-induced obesity was confirmed by the change in body weights, the fasting serum insulin (FSI) which assessed by ELISA, homeostasis model assessment - insulin resistance (HOMA-IR), fasting blood glucose (FBG), oral glucose tolerance test (OGTT) and lipid profile which were determined by colorimetric methods.
