Oral high dose vitamin B12 decreases renal superoxide and post-ischemia/reperfusion injury in mice.

Feng Li, Edward M Bahnson, Jennifer Wilder, Robin Siletzky, John Hagaman, Volker Nickekeit, Sylvia Hiller, Azraa Ayesha, Lanfei Feng, Jerrold S Levine, Nobuyuki Takahashi, Nobuyo Maeda-Smithies,

Renal ischemia/reperfusion injury (IRI) is a leading cause of acute kidney injury (AKI), a potentially fatal syndrome characterized by a rapid decline in kidney function. Excess production of superoxide contributes to the injury. We hypothesized that oral administration of a high dose of vitamin B12 (B12 - cyanocobalamin), which possesses ... Read more >>

Repeated exposure of epithelial cells to apoptotic cells induces the specific selection of an adaptive phenotype: Implications for tumorigenesis.

Lanfei Feng, Snezana Vujicic, Michael E Dietrich, Natalia Litbarg, Suman Setty, Angelika Antoni, Joyce Rauch, Jerrold S Levine,

The consequences of apoptosis extend beyond the mere death of the cell. We have shown that receptor-mediated recognition of apoptotic target cells by viable kidney proximal tubular epithelial cells (PTECs) inhibits PTEC proliferation, growth, and survival. Here, we tested the hypothesis that continual exposure to apoptotic targets can induce a ... Read more >>

Identification of Intracellular Signaling Events Induced in Viable Cells by Interaction with Neighboring Cells Undergoing Apoptotic Cell Death.

Snezana Vujicic, Lanfei Feng, Angelika Antoni, Joyce Rauch, Jerrold S Levine,

Cells dying by apoptosis, also referred to as regulated cell death, acquire multiple new activities that enable them to influence the function of adjacent live cells. Vital activities, such as survival, proliferation, growth, and differentiation, are among the many cellular functions modulated by apoptotic cells. The ability to recognize and ... Read more >>

Apoptotic and necrotic cells as sentinels of local tissue stress and inflammation: response pathways initiated in nearby viable cells.

Vimal A Patel, Daniel J Lee, Angelika Longacre-Antoni, Lanfei Feng, Wilfred Lieberthal, Joyce Rauch, David S Ucker, Jerrold S Levine,

Virtually all cells in the body have the capacity to recognize and respond to dead cells. Viable cells discriminate apo from nec targets via distinct cell surface receptors. Engagement of these receptors induces "recognition-dependent" signaling events in viable responding cells that differ for apo vs. nec targets. Although "engulfment-dependent" signaling ...

Recognition-dependent signaling events in response to apoptotic targets inhibit epithelial cell viability by multiple mechanisms: implications for non-immune tissue homeostasis.

Vimal A Patel, Lanfei Feng, Daniel J Lee, Donald Massenburg, Goutham Pattabiraman, Angelika Antoni, John H Schwartz, Wilfred Lieberthal, Joyce Rauch, David S Ucker, Jerrold S Levine,

Apoptosis allows for the removal of damaged, aged, and/or excess cells without harm to surrounding tissue. To accomplish this, cells undergoing apoptosis acquire new activities that enable them to modulate the fate and function of nearby cells. We have shown that receptor-mediated recognition of apoptotic versus necrotic target cells by ... Read more >>
