  Apoptosis Pathway Function: Apoptosis, or programmed cell death, is a critical process for removing damaged or unnecessary cells, ensuring tissue homeostasis. Location: Apoptosis occurs in various tissues throughout the body. Steps and Enzymes Involved: Intrinsic (Mitochondrial) Pathway: Step 1: Internal stress signals (e.g., DNA damage) lead to the activation of pro-apoptotic proteins such as Bax and Bak. Step 2: Bax and Bak oligomerize and form pores in the mitochondrial membrane, causing the release of cytochrome c. Step 3: Cytochrome c binds to Apaf-1, forming the apoptosome, which recruits and activates caspase-9. Step 4: Caspase-9 cleaves and activates executioner caspases, such as caspase-3 and caspase-7. Step 5: Executioner caspases degrade cellular components, leading to cell death. Extrinsic (Death Receptor) Pathway: Step 1: Extracellular signals (e.g., Fas ligand) bind to death receptors (e.g., Fas, TNF receptor). Step 2: Receptor binding recruits adaptor proteins (e.g...

Introduction: Pulmonary Arterial Hypertension (PAH) is a rare but life-threatening condition that affects the heart and lungs. It occurs when the arteries that carry blood from the heart to the lungs become narrowed, causing high blood pressure in the lungs’ arteries. Over time, this condition leads to the right side of the heart working harder than usual to pump blood, which can result in heart failure. Despite its severity, early diagnosis and treatment can improve quality of life and outcomes for those affected. Understanding PAH: PAH is classified as a type of pulmonary hypertension (PH), but it specifically refers to high blood pressure in the pulmonary arteries. The exact cause of PAH is often unknown, but it can be associated with various conditions, including connective tissue diseases, congenital heart diseases, chronic liver disease, and HIV. It can also be idiopathic, meaning no identifiable cause is found. Symptoms of PAH: Symptoms of PAH are often nonspecific, making early...
