Exploring PPAR Gamma and PPAR Alpha's Regulation Role in Metabolism via Epigenetics Mechanism.

Peroxisome proliferator-activated receptors (PPARs) belong to a family of nuclear receptors. To date, three types of PPARs, namely PPARα, PPARδ, and PPARγ, have been identified, demonstrating co-expression across numerous tissues. PPARγ is primarily distributed in adipose tissue, the colon, the immune system, and the retina, while PPARα is predominantly expressed in metabolic tissues such as brown adipose tissue, the liver, and the kidneys.

PPARs in Clinical Experimental Medicine after 35 Years of Worldwide Scientific Investigations and Medical Experiments.

This year marks the 35th anniversary of Professor Walter Wahli's discovery of the PPARs (Peroxisome Proliferator-Activated Receptors) family of nuclear hormone receptors. To mark the occasion, the editors of the scientific periodical Biomolecules decided to publish a special issue in his honor. This paper summarizes what is known about PPARs and shows how trends have changed and how research on PPARs has evolved.

DNA Content of Various Fluids and Tissues of the Human Body.

Due to the scarcity of literature data on the DNA content of different human tissues, this study aimed to isolate DNA from different tissues and fluids of the human body together with the determination of its content in the samples studied. Material was collected and tests were performed between 1990 and 2010, during autopsies performed for prosecutor's offices in the Department of Forensic Medicine. Goiter and thyroid cancer tissues were obtained from the Department of General Surgery, Gastroenterology and Endocrinology of Wroclaw Medical University.

The hero of American and Polish nations: a molecular look at Thaddeus Kosciuszko's cause of death suggests a contribution of endocarditis caused by Cutibacterium acnes infection.

The remains of the heart tissue of Thaddeus Kosciuszko have been investigated as the possible cause of disease and death of the hero of Polish and American nations. Three specimens, DNA isolated from scrappings of wax surface, from the surface of a wooden plate, and from the linen cloth that have had contact with the object were subjected to nanosequencing. From the first two, among all reads identified, only one classified as Propionibacterium acnes (synonymous current name Cutibacterium acnes), had a purported clinical significance.

Development of a procedure involving artifact examination to determine the species affiliation of its biological material, as illustrated by an attempt to demystify an alleged Nazi lampshade made from human skin.

Objectives: The main purpose of the study was to identify the species origin of the material from which the incriminating lampshade bought at a flea market had been made.

Methods: The histological and molecular biology methods commonly used in forensic genetics were selected to achieve this goal. The DNA for the research was isolated using a QIAamp DNA Mini Kit (Qiagen) according to the manufacturer's protocol for tissues.
