Hypoxia- and Xenobiotic-induced Endocrine Disruption and Obesogenicity in Fish(Dr. Richard Y C Kong)

A B C

My research group is interested in the search and elucidation of the functional roles of novel proteins/miRNAs/mechanisms/pathways that may be associated with

hypoxia- and xenobiotic-induced endocrine disruption in fish. Laboratory and/or field studies by our group have previously demonstrated that hypoxia and certain

endocrine disruptors impair testicular development, reduce sperm production/motility and deregulate various signaling pathways in male fish (Fig. A).

Importantly, we demonstrated that hypoxia-induced reproductive impairments and epigenetic changes in F0 males were transgenerationally transmitted to the F1

and F2 males (Fig. B). Retardation of gonadal development by hypoxia was also observed in the fish ovary. RNA-seq transcriptome profiling of hypoxic testes

and ovaries of the marine medaka (Oryzias melastigma) followed by Gene Ontology (GO), KEGG and Ingenuity Pathway (IPA) analysis revealed differential

expression of gender-specific signaling pathways in male and female marine medaka (Fig. C). The regulatory effect of hypoxia on medaka ovary included

activation of progesterone synthesis, activation of internal genitalia development, and inhibition of atresia of the reproductive tract. In contrast, the regulatory

effect of hypoxia on testis included modulation of signaling pathways related to cell growth and apoptosis such as G2/M DNA damage checkpoint regulation, p53

signaling and VEGF signaling. Additionally, based on recent evidence from our group, it is hypothesized that the activation or inhibition of specific hypoxia-

responsive miRNAs, directly targeting the expression of the androgen receptor (AR) or coregulators of AR signaling, represent an important pathway that controls

sexual differentiation and development in fish. Studies to verify this are currently underway in my lab. The possibility that certain endocrine-disrupting chemicals(EDCs) that are obesogenic may have a role in disrupting reproductive functions in fish is also an area that is being investigated in my lab.

Heterogeneous catalysis is highly associated

with “surface atomic arrangement” and “local

coordination” of active site !

We can map catalyst’ surface and acquire all

information such as concentration and

chemical state of surface cation, anion,

hydroxyl group and oxygen vacancy…etc. for

the investigation of true active site !
