Research Interests

The long-term goal of our research is to delineate the molecular mechanism of cell injury/death, its protection and subsequent regeneration. Our focus has continued to be the response of kidney and cancer cells/tissues to pathological conditions of hypoxia/ischemia, metabolic stress, and DNA damage. Our current work includes the investigation of cell death, cell cycle, DNA damage response, autophagy, and microRNA regulation. We have thus far published over 130 full-length articles in these and related fields. (1) We have delineated the mitochondrial pathway of apoptosis during hypoxic/ischemic kidney cell injury (Oncogene 1998; JBC 1998, 2001, 2003, 2004, 2007; AJP-renal 2004, 2006; JASN 2006; KI 2007). (2) We have revealed a rapid DNA damage response during cisplatin-induced nephrotoxicity and have further determined its pathogenic role (AJP-renal 2004, 2007; Oncogene 2006; KI 2008; JBC 2008, 2011). (3) We have discovered a novel role of Bcl-2 proteins in the regulation of mitochondrial dynamics (PNAS 2007; Cell Cycle 2007; AJP-cell 2011). Our recent work has further demonstrated the first evidence for disruption of mitochondrial dynamics in the pathogenesis of acute kidney injury-AKI (JCI 2009; AJP-renal 2010). (4) We have also demonstrated the first evidence for autophagy and its renoprotective role in AKI (KI 2008, AJP-renal 2010; AJPath 2010; KI 2012). (5) We have recently demonstrated the first evidence for an important role of microRNAs in ischemia- and cisplatin-induced AKI (JASN 2010, Mol Med 2010; AJP-renal 2011). (6) We have shown a role of PKCδ in cisplatin-induced AKI and inhibition of PKCδ may protect kidneys while enhancing cancer therapy (JCI 2011; Oncotarget 2012). (7) Our latest work has discovered Chk1-S as a new regulator of cell cycle and DNA damage response (PNAS, 2012). These studies have contributed to the understanding of the cellular responses to stress.

 mitochondria

Confocal image of mitochondria. In control cells, mitochondria are elongated and filamentous. After injury, mitochondria are fragmented into short rods or spheres. The morphological change contributes to mitochondrial damage and apoptosis (Brooks et al. PNAS 104: 11649-11654, 2007. JCI 119:1275-85, 2009).

 

  

 

   

 

   

nudemice

 

Ovarian cancer xenografts were established in nude mice, which were then treated with cisplatin with or without Rottlerin, a PKCδ inhibitor. In this and other tumor models, Rottlerin and relevant protect protect kidneys and enhance cancer therapy effect during cisplatin treatment. (Pabla et al. JCI 2011).
