FAT/CD36 (fatty acid translocase/Cluster of Differentiation 36), a plasma membrane fatty-acid transport protein, has been found on mitochondrial membranes; however, it remains unclear where FAT/CD36 resides on this organelle or its functional role within mitochondria. In the present study, we demonstrate, using several different approaches, that in skeletal muscle FAT/CD36 resides on the OMM (o...

Although PTEN has been widely described as a nuclear and cytosolic protein, in the last 2 years, alternative organelles, such as the endoplasmic reticulum (ER), pure mitochondria, and mitochondria-associated membranes (MAMs), have been recognized as pivotal targets of PTEN activity.Here, we describe different methods that have been used to highlight PTEN subcellular localization.First, a protoc...

Melanoma is a malignant tumour that originates from melanocytes. It has been reported in human beings as well many domesticated animal species (Reddy et al., 1998), and wild terrestrial marine animals. Melanomas are the most commonly diagnosed tumours oral cavity of canines (Goldschmidt, 1985; Faramade 2017). Gingiva common site for canine melanoma (OMM) but other parts like palatine, labile or...

The mechanism of Bax/Bak activation remains a central question in mitochondria-dependent apoptotic signaling. While it is established that all proapoptotic Bcl-2 homology 3 (BH3)-only proteins bind and neutralize the anti-apoptotic Bcl-2 family proteins, how this neutralization leads to Bax/Bak activation has been actively debated. Here, genome editing was used to generate cells deficient for a...

Osteopathic manipulative medicine (OMM) is a physician-directed approach to patient care that incorporates diagnostic and therapeutic strategies to address body unity issues, enhance homeostatic mechanisms, and maximize structure-function interrelationships. Osteopathic physicians integrate a thorough medical history with palpatory examination of a patient to ascertain distinctive characteristi...

Phosphatidylglycerol (PG) an important membrane phospholipid required for the synthesis of diphosphatidylglycerol (DPG) commonly known as cardiolipin (CL) was identified in the fraction of endoplasmic reticulum (ER)-derived transport vesicles which had no affinity for Golgi. The vesicles were produced in the presence of Brefeldin A (BFA), the agent known to inhibit ER-Golgi transport, and found...

MARCH5, an OMM-associated E3 ubiquitin ligase, controls mitochondrial function. Despite its importance, the mechanism and factors controlling MARCH5 activity are largely unknown. Here we report that the MARCH5 C-terminal domain plays a critical role in degradation of MARCH5 substrates, likely by facilitating release of ubiquitinated proteins from the OMM. We also found that the mitochondrial fi...
