Regulation of Molting and Skeletal Muscle Plasticity in Crabs and Lobsters
Our research concerns the regulation of molting and skeletal muscle plasticity in crabs and lobsters. Specific areas are signaling mechanisms in the molting gland and proteolytic mechanisms mediating molt-induced claw muscle atrophy. Quantitative methods are used to measure transcriptional and post-transcriptional regulation of signal transduction of molt-inhibiting hormone (MIH), a neuropeptide that inhibits ecdysteroid synthesis in the molting gland and myostatin, a TGFb superfamily member that induces skeletal muscle atrophy.

Signaling mechanisms in crustacean molting gland. Growth in crustaceans requires the periodic shedding of the shell, a process called molting, which is controlled by a neurosecretory center in the eyestalks. The complex secretes MIH that inhibits production of the molting hormone ecdysone, an ecdysteroid secreted by a pair of molting glands located in the body. Thus it appears that molting is triggered by a reduction in MIH in the blood, which stimulates the molting glands to synthesize and secrete ecdysone. It is thought that binding of MIH to a membrane receptor results in a cyclic nucleotide-dependent inhibition of ecdysone-synthesizing enzymes. Five genes were cloned in the tropical land crab that may play a role in MIH signaling: nitric oxide synthase (NOS), three guanylyl cyclases (GCs), and MIH. Proteomic approaches are used to identify and quantify levels and phosphorylation states of NOS and downstream targets of cyclic nucleotide-dependent protein kinases.

Regulation of muscle atrophy by myostatin. In mammals myostatin (Mstn) is a negative regulator skeletal muscle growth. We have recently identified Mstn orthologs in crabs and lobsters. As these genes are preferentially expressed in skeletal muscle, they may have similar functions in invertebrates. We have begun to examine the role of Mstn in controlling molt-induced claw muscle atrophy, in which the claw muscle mass is reduced as much as 78% before molting. The reduced mass facilitates withdrawal of the large claws through the narrow joints that connect the appendage to the body. Binding of Mstn to a membrane receptor results in phosphorylation of Smad proteins. Smads are transcription factors that translocate to the nucleus and alter gene expression. cDNAs encoding land crab Smads have been obtained. Quantitative RT-PCR and proteomic analysis will be used to measure Smad mRNA and protein levels, respectively. Image analysis will be used to quantify Smads in the nucleus and cytoplasm in response to Mstn.

Student Awards for the SICB Annual Meeting

Two awards will be given in the Best Student Paper competition at the Annual Meeting, one for the best oral presentation and one for the best poster presentation. Each year the award will be titled in honor of a distinguished comparative physiologist or biochemist. The name of the honored person will be selected by the DCPB Executive Committee. Each award will include a certificate and monetary prize. Undergraduate students and graduate students who have not yet been awarded the PhD are eligible for the award, as are new PhD's who have received the degree no more than 12 months prior to the meeting. The work must be original and must be carried out principally by the student presenting the paper or poster. A student who applies must be a member of the Division of Comparative Physiology and Biochemistry. In any one year, a student can enter either the oral or poster competition. A student awarded either the top DCPB poster or talk prize is not eligible for future DCPB student presentation contests. The DCPB Chair will appoint a DCPB member to chair the student competition and, in consultation with that member, will select the other judges.
