Professor H G Callan FRS, well known to all his many friends and colleagues throughout his life as Mick, was the co-founder, together with Joe Gall, of modern lampbrushology.  His greatest single contribution to the field was an exhaustive and far-reaching study of the LBCs of newts of the genus  Triturus, published jointly with his assistant Mrs. Lydia Lloyd, in 1960 (Callan & Lloyd, 1960).  The results of his many later researches, alongside those of all others in the field were brought together in his book on lampbrush chromosomes published by Springer in 1986 (Callan, 1986). 

Mick died in 1993 at the age of 76.  The accompanying photograph of him on this page was taken by Jim Kezer in 1965 at the height of Mick's scientific career when he was 49 and had just developed the highly stimulating and controversial Master/Slave theory of  molecular genetics.

An obituary can be found in Chromosome Research, 1994, 2, 83-86

Professor Joseph G Gall is a cell biologist whose work has centred on the organization and expression of genes on chromosomes. As a graduate student in the early 1950s, he examined the LBCs of the American newt Notophthalmus. He soon began to correspond with Mick Callan in Scotland, who was also studying these poorly understood structures in the European newt Triturus. Thus arose a 40-year collaboration and personal friendship that lasted until Callan's untimely death in 1993.

Gall's major interests in the amphibian germinal vesicle and LBCs can be summarised under the following headings:

Basic structure of LBCs. Gall and Callan separately worked out the basic structure of LBCs – paired sister loops extending laterally from an axis of condensed, inactive chromatin.
Transcription on LBC loops. In 1962, Gall and Callan showed that LBC loops incorporate 3H-uridine, establishing that a major function of LBCs is transcription of RNA.
Organisation of DNA in chromatid. Following the seminal observation by Macgregor and Callan that LBC loops are cleaved by DNase, Gall analyzed the kinetics of this reaction and provided direct evidence that the chromatid of a vertebrate chromosome is equivalent to a single DNA molecule.
Nuclear pore complex. Gall provided the first demonstration of octagonal symmetry in nuclear pores.
Amplified rDNA in the GV. Around 1967-68 several people more of less simultaneously "rediscovered" rDNA amplification in the amphibian GV. Using incorporation of 3H-thymidine Gall confirmed both cytologically and biochemically that rDNA amplification occurs primarily during the early prophase of the 1st meiotic division.
In situ hybridization. Using the favourable material provided by the amplified rDNA in Xenopus oocytes, Gall and Mary Lou Pardue developed the technique of in situ hybridization (1969). This technique, particularly with the later introduction of fluorescent probes, is today crucial for the subcellular localization of RNA and DNA sequences.
Organization of histone genes. Using the histone gene locus Gall and his students explored the relationships among the coding regions, the intergenic non-coding satellite type DNA, and the physical transcription units on the LBCs of the newt. They also showed the specific association of "spheres" (later histone locus bodies) with the histone gene locus.
Nuclear bodies. Gall and his students studied nuclear bodies in the amphibian GV, as well as in various tissues of Drosophila. These studies focused on two major structures, the Cajal body and the histone locus body (HLB). Both bodies contain the marker protein coilin and were confused with each other in earlier work. Cajal bodies contain components of the splicing machinery, whereas HLBs contain molecules involved in histone pre-mRNA processing. The exact relationships between the bodies and processing remain unclear.

The most recent and current studies in the Gall laboratory are reported on the News page of this website.

Joe is the American Cancer Society Professor of Developmental Genetics in the Department of Embryology of the Carnegie Institution for Science.

Professor James Kezer

Jim Kezer died at his home in Eugene Oregon on January 3rd 2002, aged 94. His obituary can be found in Chromosome Research volume 10, issue 2, page 175.

Jim Kezer was Professor of Biology at the University of Oregon in Eugene, Oregon, USA until he retired in 1974. He was born in 1908.

Jim introduced plethodontid salamanders to lampbrushologists when he visited Joe Gall's lab at the University of Minnesota in 1962. Thereafter he worked with Mick Callan (St.Andrews), Pedro Leon (Costa Rica), Herbert Macgregor (St.Andrews and Leicester), Stan Sessions (Hartwick College, N.Y.) and others in a series of investigations on a number of unique and truly remarkable features of the oocyte nuclei and lampbrush chromosomes of a range of amphibian species.

His discovery of the multinucleate oocytes of the Pacific tailed frog, Ascaphus truei (Macgregor and Kezer 1970), his studies of the lampbrush nucleolar organizer and nucleolar rings in Plethodon (Kezer and Macgregor 1973), as well as the early discovery and characterization of a centromeric satellite DNA in Plethodon [Macgregor, H.C. and J. Kezer. The chromosomal localisation of a heavy satellite DNA in the testis of Plethodon c. cinereus . Chromosoma (1973) 33: 167-182] are especially noteworthy.

Jim was also the initiating force behind one of the first ever studies to show the usefulness and significance of DNA in molecular phylogenetic studies. Without his help, advice and knowledge, Mizuno and Macgregor could not have accessed the many species of Plethodon that feature in this study [Mizuno, S. and H.C. Macgregor . Chromosomes, and sequences and evolution in salamanders of the genus Plethodon. Chromosoma (1974) 48: 239-296].

Special mention must also be made of his wide ranging cytogenetic studies of plethodontids and especially of his discovery of some spectacular examples of sex chromosome heteromorphism in Central American species [see, for example, Kezer, Sessions and Leon (1989)The meiotic structure and behaviour of the strongly heteromorphic X/Y sex chromosomes of neotropical plethodontid salamanders of the genus Oedipina. Chromosoma 98: 433 ­ 442].

To a great many biologists who graduated from the University of Oregon in the 1960s and 1970s ­ some of whom are now front line chromosome scientists - Jim Kezer is known and fondly remembered for his outstanding teaching skills which were largely founded on his tremendous enthusiasm for his subject and the sense of fun that he imparted to his students.

The accompanying photograph was taken in 1981 by Garry Morgan during a visit to Jim Kezer's home in Eugene.

Between 1990-1996 was a holder of several Wellcome Trust Fellowships for work in collaboration with Prof. H.C.Macgregor of Leicester University.
Between 1984 and 1996 developed the standard protocol for preparation of bird lampbrush chromosomes and studied their organization with special regard to (i) identification of lampbrush chromosomes in chicken, quail, turkey, and pigeon; (ii) transcription of selected sequences depending on their chromosome position; (iii) presence and function of certain hnRNPs on specific LBC loops; and (iv) chromomere composition of chicken sex W-chromosome.
Current position: Senior research scientist at the Institute of Anthropology and Human Genetics, Biozentrum, University of Munich (LMU), Germany. Current research is on the interphase nuclei. (1) Spatial organization of the interphase nucleus: positioning, shape and orientation of chromosome territories and relation of these parameters to the nuclear functions. (2) Organization of the chromosome territory: large scale chromatin folding and its relation to transcriptional activity. (3) Spatial organization of nuclei in native tissues and tissue-specific features of the nuclear and chromosomal architecture. (4) Mechanisms establishing nuclear and chromosomal architecture in the cell cycle and during terminal cell differentiation.
