Shar-Pei Mediates Cell Proliferation Arrest During Imaginal Disc Growth In Drosophila, Madhuri Kango-Singh, Riitta Nolo, Chunyao Tao, Patrik Verstreken, P. Robin Hiesinger, Hugo J. Bellen, Georg Halder
Shar-Pei Mediates Cell Proliferation Arrest During Imaginal Disc Growth In Drosophila, Madhuri Kango-Singh, Riitta Nolo, Chunyao Tao, Patrik Verstreken, P. Robin Hiesinger, Hugo J. Bellen, Georg Halder

During animal development, organ size is determined primarily by the amount of cell proliferation, which must be tightly regulated to ensure the generation of properly proportioned organs. However, little is known about the molecular pathways that direct cells to stop proliferating when an organ has attained its proper size. We have identified mutations in a novel gene, shar-pei, that is required for proper termination of cell proliferation during Drosophila imaginal disc development. Clones of shar-pei mutant cells in imaginal discs produce enlarged tissues containing more cells of normal size. We show that this phenotype is the result of both …
Inbreeding, Male Diploidy, And Complementary Sex Determination In The Solitary Wasp Euodynerus Foraminatus, Julie Kozaczka Stahlhut
Inbreeding, Male Diploidy, And Complementary Sex Determination In The Solitary Wasp Euodynerus Foraminatus, Julie Kozaczka Stahlhut
Dissertations
In the insect order Hymenoptera, which includes wasps, bees, and ants, females normally develop from fertilized eggs and are diploid, while males develop from unfertilized eggs and are haploid. Underlying mechanisms of sex determination are more complex and vary among different hymenopteran taxa. One such method is single-locus complementary sex determination, or sl-CSD, in which sex is determined by a single gene locus with many alleles. In species with sl-CSD, diploid individuals that are heterozygous at the sex locus develop as normal females and hemizygous (haploid) individuals as normal males, but diploids homozygous at the sex locus will also develop …

Electrically Mediated Delivery Of Vector Plasmid Dna Elicits An Antitumor Effect, L. Heller, D. Coppola
Electrically Mediated Delivery Of Vector Plasmid Dna Elicits An Antitumor Effect, L. Heller, D. Coppola
Bioelectrics Publications
In vivo electroporation is an efficient means of increasing plasmid DNA delivery to normal tissues, such as skin and muscle, as well as directly to tumors. In the experiments described here, plasmid DNA was delivered by in vivo electroporation to B16 mouse melanomas using two very different pulsing protocols. Reporter expression increased 21- or 42-fold, respectively with electroporation over injection alone. The growth of experimental melanomas with an approximate diameter of 4 mm on the day of treatment was monitored after electroporation delivery of reporter plasmid DNA. Remarkably, short-term complete regressions using one of these pulsing protocols occurred in up …
Eye Suppression, A Novel Function Of Teashirt, Requires Wingless Signaling, Amit Singh, Madhuri Kango-Singh, Y. Henry Sun
Eye Suppression, A Novel Function Of Teashirt, Requires Wingless Signaling, Amit Singh, Madhuri Kango-Singh, Y. Henry Sun
Biology Faculty Publications
Teashirt (tsh) encodes a Drosophila zinc-finger protein. Misexpression of tsh has been shown to induce ectopic eye formation in the antenna. We report that tsh can suppress eye development. This novel function of tsh is due to the induction of homothorax (hth), a known repressor of eye development, and requires Wingless (WG) signaling. Interestingly, tsh has different functions in the dorsal and ventral eye, suppressing eye development close to the ventral margin, while promoting eye development near the dorsal margin. It affects both growth of eye disc and retinal cell differentiation.

Effect Of Electrically Mediated Intratumor And Intramuscular Delivery Of A Plasmid Encoding Ifn Α On Visible B16 Mouse Melanomas, Loree C. Heller, Stephanie F. Ingram, M. Lee Lucas, Richard A. Gilbert, Richard Heller
Bioelectrics Publications
Interferon α may be used as a single agent therapy for metastatic malignant melanoma or as an adjuvant to chemotherapy. Delivery of interferon α by gene therapy offers an alternative to recombinant protein therapy. Electrically mediated delivery enhances plasmid expression in a number of tissues, for instance skin, liver, muscle and tumors including melanomas. Here we compare the effect of delivery of a plasmid encoding mouse interferon α on growth of visible B16 mouse melanomas following electrically mediated delivery to muscle or directly to the tumor. Intratumoral delivery of interferon α plasmid not only slows melanoma growth, but induces complete, …
Caudal Spotting In The Beacon Fish (Hemigrammus Ocellifer Characidae), Jack Frankel
Caudal Spotting In The Beacon Fish (Hemigrammus Ocellifer Characidae), Jack Frankel
Department of Biology Faculty Publications
The beacon fish (Hemigrammus ocellifer) exhibits two phenotypes associated with spotting at the base of the caudal fin, with fish either possessing (H. o. ocellifer) or lacking (H. o. falsus) a prominent red spot in this region. Segregation patterns observed from the progenies of 15 different crosses support a hypothesis that caudal spotting in this species is controlled by a single gene with two alleles, for which the caudal spotting allele is completely dominant.

Comparative Genomic Hybridization Array Analysis, Annette M. Molinaro, Mark J. Van Der Laan, Dan H. Moore
U.C. Berkeley Division of Biostatistics Working Paper Series
At the present time, there is increasing evidence that cancer may be regulated by the number of copies of genes in tumor cells. Through microarray technology it is now possible to measure the number of copies of thousands of genes and gene segments in samples of chromosomal DNA. Microarray comparative genomic hybridization (array CGH) provides the opportunity to both measure DNA sequence copy number gains and losses and map these aberrations to the genomic sequence. Gains can signify the over-expression of oncogenes, genes which stimulate cell growth and have become hyperactive, while losses can signify under-expression of tumor suppressor genes, …
Use Of The Caulobacter Crescentus Genome Sequence To Develop A Method For Systematic Genetic Mapping, Craig Stephens, Lisandra West, Desiree Yang
Use Of The Caulobacter Crescentus Genome Sequence To Develop A Method For Systematic Genetic Mapping, Craig Stephens, Lisandra West, Desiree Yang
Biology
The functional analysis of sequenced genomes will be facilitated by the development of tools for the rapid mapping of mutations. We have developed a systematic approach to genetic mapping in Caulobacter crescentus that is based on bacteriophage-mediated transduction of strategically placed antibiotic resistance markers. The genomic DNA sequence was used to identify sites distributed evenly around the chromosome at which plasmids could be nondisruptively integrated. DNA fragments from these sites were amplified by PCR and cloned into a kanamycin-resistant (Kanr) suicide vector. Delivery of these plasmids into C. crescentus resulted in integration via homologous recombination. A set of 41 strains …
Production Of A Monoclonal Antibody Against Benzo[Α]Pyrene Diol Epoxide Dna Adducts, Brian Peden Austin
Production Of A Monoclonal Antibody Against Benzo[Α]Pyrene Diol Epoxide Dna Adducts, Brian Peden Austin
Chemistry & Biochemistry Theses & Dissertations
Benzo[α]pyrene is a ubiquitous pollutant produced from the incomplete combustion of organic material such as fossil fuels. It is found in the workplace, urban air, drinking water, and the food supply. Recently, it has been proposed that benzo[α]pyrene may be the causative agent in the formation of lung adenocarcinomas among some Taiwanese women exposed to cooking oil fumes without adequate ventilation. In this study, calf thymus DNA was modified in vitro with benzo[α]pyrene-diol epoxide (BPDE) to a level consistent with that found in biological samples. This DNA of low modification was used as an immunogen in the production of a …

Editor's Note, Padraig O'Malley
New England Journal of Public Policy
This issue of the journal can be summed up in one word: provocative. At least two articles break new ground. Anthony Robbins and Phyllis Freeman explore the ways in which environmentally oriented public health is uniquely suited to help organized medical care in providing health and in restraining expenditures. Janet Farrell Smith challenges policymakers to look at what will soon become a hot issue — the medical use of genetic information. The genetic testing of children, now becoming prevalent in the foster care and pre-adoptive stage in order to facilitate placement and satisfy prospective parents’ “need to know,” is already …
Genetic Testing: A Cautionary Tale Of Foster And Pre-Adoptive Children, Janet Farrell Smith
Genetic Testing: A Cautionary Tale Of Foster And Pre-Adoptive Children, Janet Farrell Smith
New England Journal of Public Policy
Genetic testing of children in the foster care and pre-adoptive stage may be thought to facilitate child placement and satisfy prospective parents’ need to know. But, the policy analysis in this paper recommends great caution, especially given eugenic attitudes in the history of adoption and the risk of creating a second tier of un-adoptable children. Testing should be done only when two conditions are satisfied: test information is medically useful for childhood onset diseases; test information supports and does not diminish the child’s access to present and future healthcare (or the child’s future insurability). Public policy needs to make a …
Neurospora Clock-Controlled Gene 9 (Ccg-9) Encodes Trehalose Synthase: Circadian Regulation Of Stress Responses And Development, Mari L. Shinohara, Alejandro Correa, Deborah Bell-Pedersen, Jay C. Dunlap, Jennifer J. Loros
Neurospora Clock-Controlled Gene 9 (Ccg-9) Encodes Trehalose Synthase: Circadian Regulation Of Stress Responses And Development, Mari L. Shinohara, Alejandro Correa, Deborah Bell-Pedersen, Jay C. Dunlap, Jennifer J. Loros
Dartmouth Scholarship
The circadian clock of Neurospora crassa regulates the rhythmic expression of a number of genes encoding diverse functions which, as an ensemble, are adaptive to life in a rhythmic environment of alternating levels of light and dark, warmth and coolness, and dryness and humidity. Previous differential screens have identified a number of such genes based solely on their cycling expression, including clock-controlled gene 9 (ccg-9). Sequence analysis now shows the predicted CCG-9 polypeptide to be homologous to a novel form of trehalose synthase; as such it would catalyze the synthesis of the disaccharide trehalose, which plays an important …
A New Partitioning Around Medoids Algorithm, Mark J. Van Der Laan, Katherine S. Pollard, Jennifer Bryan
A New Partitioning Around Medoids Algorithm, Mark J. Van Der Laan, Katherine S. Pollard, Jennifer Bryan
U.C. Berkeley Division of Biostatistics Working Paper Series
Kaufman & Rousseeuw (1990) proposed a clustering algorithm Partitioning Around Medoids (PAM) which maps a distance matrix into a specified number of clusters. A particularly nice property is that PAM allows clustering with respect to any specified distance metric. In addition, the medoids are robust representations of the cluster centers, which is particularly important in the common context that many elements do not belong well to any cluster. Based on our experience in clustering gene expression data, we have noticed that PAM does have problems recognizing relatively small clusters in situations where good partitions around medoids clearly exist. In this …

Compensation For Herbivory In Wild Sunflower: Response To Simulated Damage By The Head-Clipping Weevil, Diana Pilson, Karin L. Decker
Compensation For Herbivory In Wild Sunflower: Response To Simulated Damage By The Head-Clipping Weevil, Diana Pilson, Karin L. Decker
Diana Pilson Publications
Herbivore damage is generally detrimental to plant fitness, and the evolutionary response of plant populations to damage can involve either increased resistance or increased tolerance. While characters that contribute to resistance, such as secondary chemicals and trichomes, are relatively well understood, characters that contribute to a plant’s ability to tolerate damage have received much less attention. Using Helianthus annuus (wild sunflower) and simulated damage of Haplorhynchites aeneus (head-clipping weevil) as a model system, we examined morphological characters and developmental processes that contribute to compensatory ability. We performed a factorial experiment that included three levels of damage (none, the first two, …

A Note On Cascade Climbing Of Migrating Goby And Shrimp Postlarvae In Two Maui Streams, M. Eric Benbow, Leslie Luchar Orzetti, Mollie D. Mcintosh, Albert J. Burky
Biology Faculty Publications
In this study, we documented cascade climbing rates of 133 and 230 postlarvae of Lentipes concolor (O‘opu alamo‘o) and Atyoida bisulcata (Opae kahaole), respectively, from two streams on the island of Maui, Hawaii. Climbing measurements and observations were made of postlarvae at the water-substrate interface in cascade habitats of constricted water flow. Both species were observed to move in short bursts of forward progression within or above the pulsing water-substrate interface. Goby postlarval climbing rates ranged from 0.04 – 1.50 cm s–1 and were slower than shrimp rates which ranged from 0.30 – 3.06 cm s–1. The high variability is …

Lawrence G. Harshman Publications
The purpose of this study was to investigate medfly longevity and reproduction across a broad spectrum of diet restriction using a protocol similar to those applied in most rodent studies. Age-specific reproduction and age of death were monitored for 1,200 adult males and 1,200 females, each individually maintained on one of 12 diets from ad libitum to 30% of ad libitum. Diet was provided in a fixed volume of solution that was fully consumed each day, ensuring control of total nutrient consumption for every fly. Contrary to expectation and precedence, increased longevity was not observed at any level of …

Il-12 Plasmid Delivery By In Vivo Electroporation For The Successful Treatment Of Established Subcutaneous B16.F10 Melanoma, M. Lee Lucus, Loree Heller, Domenico Coppola, Richard Heller
Bioelectrics Publications
Interleukin-12 (IL-12) has been used in numerous immunotherapy protocols against melanoma. However, delivery of IL-12 in the form of recombinant protein can result in severe toxicity, and gene therapy has had limited success against B16.F10 murine melanoma. The purpose of this study was to examine the effectiveness of in vivo electroporation for the delivery of plasmid DNA encoding IL-12 as an antitumor agent against B16.F10 melanoma. We treated mice bearing established B16.F10 melanoma tumors with intratumoral (i.t.) or intramuscular (i.m.) injections of a plasmid encoding IL-12, followed by in vivo electroporation. For i.t. treatments, we used an applicator containing six …

Genetic Stock Structure Of The Sailfish, Istiophorus Platypterus, Based On Nuclear And Mitochondrial Dna, Jan Renee Mcdowell
Dissertations, Theses, and Masters Projects
The results of life history studies involving the sailfish, Istiophorus platypterus, from the Atlantic, Pacific, and Indian oceans were reviewed. Results of studies agree on several aspects of sailfish biology; sailfish exhibit opportunistic feeding behavior, follow the 28??C isotherm, spawn in summer mature at approximately age 3, and are the least migratory of the billfishes. However, results are in conflict concerning sex ratio and whether sailfish are single or multiple spawners. Although many researchers have reported that sailfish are sexually dimorphic, their fragile otoliths make them difficult to age, aging studies have not been validated, and sexual dimorphism has not …

The distribution and function of aquaporins (AQPs) have not previously been defined in sweat glands. In this study, AQP1, AQP3, and AQP5 mRNA were demonstrated in rat paw by reverse transcription (RT)–PCR, but AQP2 and AQP4 were not. AQP1, AQP3, and AQP5 protein were confirmed in these tissues by immunoblotting. AQP1 was identified in capillary endothelial cells by immunohistochemical labeling, but not in sweat glands or epidermis. Abundant AQP3 expression was seen in basal levels of epidermis, but not in sweat glands. AQP2 and AQP4 were not observed in either skin or sweat glands. Immunohistochemical labeling revealed abundant AQP5 in …
Molecular And Morphological Evolution Of The Amphipod Radiation Of Lake Baikal, Kenneth S. Macdonald Iii
Molecular And Morphological Evolution Of The Amphipod Radiation Of Lake Baikal, Kenneth S. Macdonald Iii
Dissertations, Theses, and Masters Projects
The amphipods of Lake Baikal, Russia, are a taxonomically and morphologically diverse group, and have been cited as a classic example of adaptive radiation. An unfortunate consequence of this diversity has been an instability of Baikal amphipod classification, with frequent revisions spurred by differing opinions about the phylogenetic utility of different characters. Classifications have never been based on a rigorous phylogenetic analysis of morphological data and only recently has the phylogeny of Lake Baikal's amphipods been examined using molecular tools. Unfortunately, most of these studies have led to a limited expansion of our understanding of Baikal amphipod systematics. Phylogenetic relationships …
