Multiple myeloma (MM) is a hematologic malignancy characterized by uncontrolled proliferation of plasma cells in the bone marrow. MM patients with aggressive progression have poor survival, emphasizing the urgent need for identifying new therapeutic targets. Here, we show that the leukocyte immunoglobulin-like receptor B1 (LILRB1), a transmembrane receptor conducting negative immune response, is a top-ranked gene associated with poor prognosis in MM patients. LILRB1 deficiency inhibits MM progression in vivo by enhancing the ferroptosis of MM cells. Mechanistic studies reveal that LILRB1 forms a complex with the low-density lipoprotein receptor (LDLR) and LDLR adapter protein 1 (LDLRAP1) to facilitate LDL/cholesterol …

Vertebral Hu Value And The Pectoral Muscle Index Based On Chest Ct Can Be Used To Opportunistically Screen For Osteoporosis, Xiong-Yi Wang, Sheng Pan, Wei-Feng Liu, Yi-Ke Wang, Si-Min Yun, You-Jia Xu

Faculty, Staff and Student Publications

BACKGROUND: Existing studies have shown that computed tomography (CT) attenuation and skeletal muscle tissue are strongly associated with osteoporosis; however, few studies have examined whether vertebral HU values and the pectoral muscle index (PMI) measured at the level of the 4th thoracic vertebra (T4) are strongly associated with bone mineral density (BMD). In this study, we demonstrate that vertebral HU values and the PMI based on chest CT can be used to opportunistically screen for osteoporosis and reduce fracture risk through prompt treatment.

METHODS: We retrospectively evaluated 1000 patients who underwent chest CT and DXA scans from August 2020-2022. The …

Characterizing The Expression Of The Sphingosine 1-Phosphate Pathway In Injury And Post-Traumatic Fibrosis, Nicole Cubbage

Masters Theses, 2020-current

Following injury, tissue repair allows for the restoration of the architecture and function of the injured tissue, while tissue replacement is characterized by severely damaged or non-regenerable tissue that is repaired by the laying down of extensive connective tissue, also known as fibrosis. The fibrotic process should be arrested at its early stage to have the greatest impact on preventing or reversing associate sequelae and promoting the regeneration of normal tissue. Sphingosine 1-phosphate (S1P), a metabolic product of cell membrane sphingolipids, has emerged as a pathway that may be involved in fibrosis. Most of S1P’s actions are mediated through the …

A Literature Review Of Pain Control In Osteoarthritis Patients Using Blood Flow Restriction Training, John Gericke, Dakota Pastore, Tyler Pigott

Rowan-Virtua Research Day

Background: Osteoarthritis (OA) is a degenerative disease that mainly affects articular cartilage of joints. OA most commonly affects the knees and causes pain and reduces quality of life in older adults. Blood flow restriction (BFR) occludes arterial and venous flow during exercise using a blood pressure cuff placed on the proximal lower limb. This creates an intramuscular hypoxic environment which promotes muscle hypertrophy. High load training can cause pain and inflammation in knee OA patients due to increased stress. BFR can allow patients with knee OA to use lower loads to achieve beneficial effects of rehabilitation.

Methods: Data was ascertained …
