Multiple types of cerebellar target neurons and their circuitry in the vestibulo-ocular reflex.

The cerebellum influences behavior and cognition exclusively via Purkinje cell synapses onto neurons in the deep cerebellar and vestibular nuclei. In contrast with the rich information available about the organization of the cerebellar cortex and its synaptic inputs, relatively little is known about microcircuitry postsynaptic to Purkinje cells. Here we examined the cell types and microcircuits through which Purkinje cells influence an oculomotor behavior controlled by the cerebellum, the horizontal vestibulo-ocular reflex, which involves only two eye muscles.

Genetic deficiency in Pparg does not alter development of experimental prostate cancer.

The role of the nuclear peroxisome proliferator-activated receptor (PPAR)-gamma in cancer has been a subject of debate. The identification of loss-of-function mutations in PPARG in colon and prostate tumors has led to the idea that this gene may function as a tumor suppressor. We have directly tested this notion using a mouse model of prostate cancer.
