Manganese Chloride Effects Chondrogenesis Of Atdc5 Cells, Isabella Somera

Seton Hall University Dissertations and Theses (ETDs)

Manganese is an essential trace element found in humans, which aids in several processes including brain and nerve function, glucose metabolism, calcium absorption, and bone formation and homeostasis. Specifically, bone homeostasis utilizes osteoblasts and osteoclasts, cells which function to build and reabsorb bone respectively, as well as chondrocytes, cells which aid in endochondral ossification. Chondrocytes deposit extracellular matrix components, such as aggrecan, collagen, and proteoglycans, that provide the necessary scaffold for osteoblasts to synthesize and mineralize bone. Activation of the rapamycin (mTOR) pathway influences the regulation of several cellular processes, such as skeletal development and bone homeostasis. In this study, …

Investigation Of The Effect Of Trace Element, Copper Chloride, On Chondrogenic Cell Line, Atdc5 Function, Alexandra Bambrick

Seton Hall University Dissertations and Theses (ETDs)

Copper chloride (CuCl₂) is an essential trace element found in humans, which helps to aid in brain and nerve function, glucose metabolism, calcium absorption, and bone formation. Bone formation utilizes a variety of cell types, including, osteoblasts, osteoclasts, and chondrocytes. Chondrocytes deposit cartilage components like collagen and proteoglycans that provide the necessary scaffold for osteoblasts to synthesize and mineralize bone. Copper chloride is known to aid in osteogenesis, maintain bone metabolism, and regulate bone mineral density, but its role in chondrogenesis is still unclear (15).

In this study, it is hypothesized that CuCl₂ treatments would enhance chondrogenic …

Bis-Indolyl Compounds And The Induction Of Apoptosis In T98g Glioblastoma Multiforme Cells, Margot C. Brown

Seton Hall University Dissertations and Theses (ETDs)

1,1-bis(3’idolyl)-1(aryl)methane compounds (BIM compounds) have been shown to have anti-cancer properties in colon cancer, bladder cancer, and leukemia cells. The purpose of this work was to determine if BIM compounds could be an effective treatment of glioblastoma multiforme. Sulforhodamine B (SRB) assays showed that 20µM of the BIM compounds could inhibit cellular proliferation of the T98G glioblastoma multiforme cell line over 72 hours. Then immunoblotting was used to analyze the molecular pathway induced by BIM compounds. An increase in the expression of both BAX and cleaved caspase 3 suggest BIM compounds activate programmed cell death, or apoptosis in glioblastoma cells. …
