Abstract
Aging is emerging as a druggable target with growing interest from academia, industry and investors. New technologies such as artificial intelligence and advanced screening techniques, as well as a strong influence from the industry sector may lead to novel discoveries to treat age-related diseases. The present review summarizes presentations from the 7th Annual Aging Research and Drug Discovery (ARDD) meeting, held online on the 1st to 4th of September 2020. The meeting covered topics related to new methodologies to study aging, knowledge about basic mechanisms of longevity, latest interventional strategies to target the aging process as well as discussions about the impact of aging research on society and economy. More than 2000 participants and 65 speakers joined the meeting and we already look forward to an even larger meeting next year. Please mark your calendars for the 8th ARDD meeting that is scheduled for the 31st of August to 3rd of September, 2021, at Columbia University, USA.

Abstract
Nucleotide excision repair (NER) is one of the main DNA repair pathways that protect cells against genomic damage. Disruption of this pathway can contribute to the development of cancer and accelerate aging. Mutational characteristics of NER-deficiency may reveal important diagnostic opportunities, as tumors deficient in NER are more sensitive to certain treatments. Here, we analyzed the genome-wide somatic mutational profiles of adult stem cells (ASCs) from NER-deficient Ercc1 -/Δ mice. Our results indicate that NER-deficiency increases the base substitution load twofold in liver but not in small intestinal ASCs, which coincides with the tissue-specific aging pathology observed in these mice. Moreover, NER-deficient ASCs of both tissues show an increased contribution of Signature 8 mutations, which is a mutational pattern with unknown etiology that is recurrently observed in various cancer types. The scattered genomic distribution of the base substitutions indicates that deficiency of global-genome NER (GG-NER) underlies the observed mutational consequences. In line with this, we observe increased Signature 8 mutations in a GG-NER-deficient human organoid culture, in which XPC was deleted using CRISPR-Cas9 gene-editing. Furthermore, genomes of NER-deficient breast tumors show an increased contribution of Signature 8 mutations compared with NER-proficient tumors. Elevated levels of Signature 8 mutations could therefore contribute to a predictor of NER-deficiency based on a patient's mutational profile.

Abstract
Cancer cells that acquire radio-resistance are major problem for treatment outcome. We aimed at identifying mechanisms and networks that control ionizing radiation (IR)-resistance in prostate cancer cells. To this end, we applied to cancer cell lines an identical radiotherapy regiment as performed in the clinic, i.e. a total dose of 78 Gy in steps of 2 Gy per day for 5 consecutive days followed by 2 days rest. We observed that radio-resistance occurs early during treatment as seen in colony survival assays in which 100% of cells that can form colonies are resistant up to 8 Gy. Remarkably, a two-week period of culturing without radiotherapy completely sensitized these resistant cancer cell lines, indicating that resistance is not acquired by permanent mutations or chromosomal rearrangements. Currently, we are characterizing these extreme resistant cancer cell cultures by comparing these to their sensitive parental cancer cell lines and the two-week re-sensitized cancer cell lines. We observe changes in DNA repair pathway utilization, DNA damage checkpoint activation and energy metabolism parameters, but not in PI3-kinase signalling and cancer stem cell markers. We also performed genome-wide gene expression analysis by next generation sequencing and isolated gene signatures that correlate with resistance. Based on our results we applied inhibitors to sensitize these IR-resistant cells. Notably, application of single inhibitors did not lead to sensitivity. Combinations of small molecule inhibitors however, were able to sensitize these cancer cell lines, indicating that IR-resistance is a multi-factorial process. In summary, mapping gene networks and mechanisms will uncover new pathways associated with IR-resistance.

Abstract
High levels of aneuploidy have been observed in disease-free tissues, including post-mitotic tissues such as the brain. Using a quantitative interphase-fluorescence in situ hybridization approach, we previously reported a chromosome-specific, age-related increase in aneuploidy in the mouse cerebral cortex. Increased aneuploidy has been associated with defects in DNA repair and the spindle assembly checkpoint, which in turn can lead to premature aging. Here, we quantified the frequency of aneuploidy of three autosomes in the cerebral cortex and cerebellum of adult and developing brain of Bub1b(H/H) mice, which have a faulty mitotic checkpoint, and Ercc1(-/Δ7) mice, defective in nucleotide excision repair and inter-strand cross-link repair. Surprisingly, the level of aneuploidy in the brain of these murine models of accelerated aging remains as low as in the young adult brains from control animals, i.e. <1% in the cerebral cortex and ∼0.1% in the cerebellum. Therefore, based on aneuploidy, these adult mice with reduced life span and accelerated progeroid features are indistinguishable from age-matched, normal controls. Yet, during embryonic development, we found that Bub1b(H/H), but not Ercc1(-/Δ7) mice, have a significantly higher frequency of aneuploid nuclei relative to wild-type controls in the cerebral cortex, reaching a frequency as high as 40.3% for each chromosome tested. Aneuploid cells in these mutant mice are likely eliminated early in development through apoptosis and/or immune-mediated clearance mechanisms, which would explain the low levels of aneuploidy during adulthood in the cerebral cortex of Bub1b(H/H) mice. These results shed light on the mechanisms of removal of aneuploidy cells in vivo.

Abstract
Hair thinning and loss are prominent aging phenotypes but have an unknown mechanism. We show that hair follicle stem cell (HFSC) aging causes the stepwise miniaturization of hair follicles and eventual hair loss in wild-type mice and in humans. In vivo fate analysis of HFSCs revealed that the DNA damage response in HFSCs causes proteolysis of type XVII collagen (COL17A1/BP180), a critical molecule for HFSC maintenance, to trigger HFSC aging, characterized by the loss of stemness signatures and by epidermal commitment. Aged HFSCs are cyclically eliminated from the skin through terminal epidermal differentiation, thereby causing hair follicle miniaturization. The aging process can be recapitulated by Col17a1 deficiency and prevented by the forced maintenance of COL17A1 in HFSCs, demonstrating that COL17A1 in HFSCs orchestrates the stem cell-centric aging program of the epithelial mini-organ.

Abstract
Gain-of-function missense mutations in voltage-gated sodium channel Nav1.7 have been linked to small-fiber neuropathy, which is characterized by burning pain, dysautonomia and a loss of intraepidermal nerve fibers. However, the mechanistic cascades linking Nav1.7 mutations to axonal degeneration are incompletely understood. The G856D mutation in Nav1.7 produces robust changes in channel biophysical properties, including hyperpolarized activation, depolarized inactivation, and enhanced ramp and persistent currents, which contribute to the hyperexcitability exhibited by neurons containing Nav1.8. We report here that cell bodies and neurites of dorsal root ganglion (DRG) neurons transfected with G856D display increased levels of intracellular Na(+) concentration ([Na(+)]) and intracellular [Ca(2+)] following stimulation with high [K(+)] compared with wild-type (WT) Nav1.7-expressing neurons. Blockade of reverse mode of the sodium/calcium exchanger (NCX) or of sodium channels attenuates [Ca(2+)] transients evoked by high [K(+)] in G856D-expressing DRG cell bodies and neurites. We also show that treatment of WT or G856D-expressing neurites with high [K(+)] or 2-deoxyglucose (2-DG) does not elicit degeneration of these neurites, but that high [K(+)] and 2-DG in combination evokes degeneration of G856D neurites but not WT neurites. Our results also demonstrate that 0 Ca(2+) or blockade of reverse mode of NCX protects G856D-expressing neurites from degeneration when exposed to high [K(+)] and 2-DG. These results point to [Na(+)] overload in DRG neurons expressing mutant G856D Nav1.7, which triggers reverse mode of NCX and contributes to Ca(2+) toxicity, and suggest subtype-specific blockade of Nav1.7 or inhibition of reverse NCX as strategies that might slow or prevent axon degeneration in small-fiber neuropathy.

Abstract
Genome maintenance (GM) is an essential defense system against aging and cancer, as both are characterized by increased genome instability. Here, we compared the copy number variation and mutation rate of 518 GM-associated genes in the naked mole rat (NMR), mouse, and human genomes. GM genes appeared to be strongly conserved, with copy number variation in only four genes. Interestingly, we found NMR to have a higher copy number of CEBPG, a regulator of DNA repair, and TINF2, a protector of telomere integrity. NMR, as well as human, was also found to have a lower rate of germline nucleotide substitution than the mouse. Together, the data suggest that the long-lived NMR, as well as human, has more robust GM than mouse and identifies new targets for the analysis of the exceptional longevity of the NMR.

Abstract
Abstract
One of the hallmarks of cancer is genetic instability. Many chemotherapeutic strategies make use of DNA damaging agents, that preferentially target dividing cells. Recently, DNA repair defects have been identified in many different types of tumors, suggesting that the effectiveness of such treatments may be modulated by the precise genetic make-up of the tumor; defects in specific DNA repair pathways can be used as the Achilles' Heel of the tumor. An important new concept is synthetic lethality, the observation that combinations of mutations can be lethal, while both single mutations are viable. In selected tumors, the specific DNA repair defect can be targeted in such a way that the tumor cells can be killed without causing severe side effect on normal tissues. The combination of PARP inhibitors and homologous recombination (HR) deficient hereditary breast cancer is on its way to the clinic and more combinations are currently in the preclinical phase. Selection of breast cancer patients for targeted treatment with PARP inhibitors requires a validated test to identify HR deficient tumors. For this purpose, we have assessed ionizing radiation induced RAD51 foci (IRIF) after ex vivo irradiation of individual breast tumor slices as a marker for HR defects. We validated this approach in known HR- deficient tumors, where we found a severe defect in RAD51 IRIF formation. Subsequently, we used this assay to identify a subgroup of HR deficient primary breast cancers. Out of 42 tumors, we found five HR deficient breast cancers, caused by two distinct modes of BRCA gene inactivation, mutations and promoter hypermethylation. HR deficiency was significantly associated with high grade, triple-negative breast cancer (TNBC). A large fraction of TNBC showed HR defects, suggesting that PARP inhibitors may be particularly promising for this group of tumors that currently have a poor prognosis. We conclude that the RAD51 IRIF assay is a powerful tool to select patients with HR-deficient primary breast cancers eligible for PARP-inhibitor treatment in the clinic. These approaches may change cancer medicine in a fundamental way, from a one-size-fits-all concept to an individualized treatment strategy based on the functional molecular make-up of the tumor for each patient.

Abstract
A gradual loss of the correct patterning of 5-methyl cytosine marks in gene promoter regions has been implicated in aging and age-related diseases, most notably cancer. While a number of studies have examined DNA methylation in aging, there is no consensus on the magnitude of the effects, particularly at imprinted loci. Imprinted genes are likely candidate to undergo age-related changes because of their demonstrated plasticity in utero, for example, in response to environmental cues. Here we quantitatively analyzed a total of 100 individual CpG sites in promoter regions of 11 imprinted and non-imprinted genes in liver and cerebral cortex of young and old mice using mass spectrometry. The results indicate a remarkably high preservation of methylation marks during the aging process in both organs. To test if increased genotoxic stress associated with premature aging would destabilize DNA methylation we analyzed two DNA repair defective mouse models showing a host of premature aging symptoms in liver and brain. However, also in these animals, at the end of their life span, we found a similarly high preservation of DNA methylation marks. We conclude that patterns of DNA methylation in gene promoters of imprinted genes are surprisingly stable over time in normal, postmitotic tissues and that the multiple documented changes with age are likely to involve exceptions to this pattern, possibly associated with specific cellular responses to age-related changes other than genotoxic stress.

Abstract
Objective
Recently we discovered that genomic instability is associated with accelerated vascular aging in humans and mouse models, and that DNA repair-defective mice (
ERCC1
-/
Δ
7
) display accelerated age-dependent deterioration of endothelium-dependent and vascular smooth muscle dilator function (Durik M. et al. Circulation 2012).
Dietary restriction (
DR
) is known to slow aging. We explored whether
DR
would inhibit accelerated vascular aging caused by genomic instability by measuring vasodilator function in both male and female
ERCC1
-/
Δ
7
mice vs. wild-type (WT) littermates.
Methods
WT and ERCC1
-/
Δ
7
were fed with
DR
(increasing 10 to 30% nutrient restriction) or ad libitum (
AL
)
diets for 9 weeks, whereafter
thoracic aortas were isolated and used for
ex vivo
organ bath experiments. To investigate endothelial and vascular smooth muscle dilator function, aorta preconstricted with U44619 (thromboxane analogue) was exposed to acetylcholine (Ach: 10
-9
-10
-5
M) and sodium nitroprusside (SNP: 10
-9
-10
-4
M), respectively. Maximal dilator responses (mean+/-SEM) are shown between brackets, and were calculated as % decrease of precontraction. Significance values are those of dose-related responses tested by general linear model for repeated measures.
Results
In ERCC1
-/
Δ
7
mice fed
AL
both ACh and SNP responses were significantly smaller than in WT (Ach: 66.89+/-8.9% (n=8)
vs.
41.45+/-4.74% (n=11); SNP: 80.27+/-4.89% (n=5)
vs.
59.35+/-3.32% (n=5),
p

vs.

) with no gender differences. Whilst without effect in WT,
DR
normalized the SNP responses of ERCC1
-/
Δ

(79.60+/-7.09% (n=6)) to that of WT gender-independently. ACh responses were also improved (from 41.45+/-4.74%
AL
(n=11) to 56.02+/-4.73%
DR
(n=11)), but most pronounced in female ERCC1

(38.33+/-8.39%
AL
(n=4)
vs.
-67.31+/-6.22%
DR
(n=4)
, p
<0.0001).
Conclusion
In ERCC1
-/Δ7
mice, DR improved vasodilator response in both genders. Endothelial function might be improved only efficiently in female mice, whilst the NO-mediated dilation of VSMC is improved equally well in both genders. Therefore,
DR
is beneficial for vascular function during vascular aging caused by genomic instability, and its impact on EC versus VSMC appears to be gender-dependent.

Abstract
Lymphocyte activation is initiated by a global increase in messenger RNA synthesis. However, the mechanisms driving transcriptome amplification during the immune response are unknown. By monitoring single-stranded DNA genome wide, we show that the genome of naive cells is poised for rapid activation. In G0, ∼90% of promoters from genes to be expressed in cycling lymphocytes are polymerase loaded but unmelted and support only basal transcription. Furthermore, the transition from abortive to productive elongation is kinetically limiting, causing polymerases to accumulate nearer to transcription start sites. Resting lymphocytes also limit the expression of the transcription factor IIH complex, including XPB and XPD helicases involved in promoter melting and open complex extension. To date, two rate-limiting steps have been shown to control global gene expression in eukaryotes: preinitiation complex assembly and polymerase pausing. Our studies identify promoter melting as a third key regulatory step and propose that this mechanism ensures a prompt lymphocyte response to invading pathogens.

Abstract
Abstract
UV-induced DNA damage is an essential step in the process by which UVB can alter host resistance to infections diseases. UV-light induces two types of photolesion on DNA that are repaired by photolyases (absent in placental mammals) or Nucleotide Excision Repair. Photolyases are capable of repair these lesions using a photon of light as source of energy. Although the deleterious effects of UV are widely known, the specific role of each photolesion in the induction of changes in the immune response remains unknown. It has been shown in vivo that CPDs are responsible for the majority of the effects after UVB skin irradiation of DNA repair proficient mice, such as erythema, apoptosis, hyperplasia, tumorigenesis and immunosuppression. However the role of 6-4PP is still unknown. We show that the removal of CPD lesions prevents hyperplasia and induces dark skin pigmentation. When 6-4PPs were removed, UVB promoted hyperplasia and tanning. Also, unlike 6-4PP removal, CPD removal is capable of preventing the development of p53 epidermal patches, which have a direct correlation with carcinoma development. Furthermore, the CPD removal is sufficient to suppress the induction of Treg (CD4+CD25+Foxp3) in draining lymph nodes and spleen indicating a minor state of immunosuppression. This study can provide new information as how immune responses are regulated depending of the lesion that is repaired and improve our understanding the immune system role in skin cancer induction.

Abstract
Unrepaired or misrepaired DNA damage has been implicated as a causal factor in cancer and aging. Xpd(TTD) mice, harboring defects in nucleotide excision repair and transcription due to a mutation in the Xpd gene (R722W), display severe symptoms of premature aging but have a reduced incidence of cancer. To gain further insight into the molecular basis of the mutant-specific manifestation of age-related phenotypes, we used comparative microarray analysis of young and old female livers to discover gene expression signatures distinguishing Xpd(TTD) mice from their age-matched wild type controls. We found a transcription signature of increased apoptosis in the Xpd(TTD) mice, which was confirmed by in situ immunohistochemical analysis and found to be accompanied by increased proliferation. However, apoptosis rate exceeded the rate of proliferation, resulting in homeostatic imbalance. Interestingly, a metabolic response signature was observed involving decreased energy metabolism and reduced IGF-1 signaling, a major modulator of life span. We conclude that while the increased apoptotic response to endogenous DNA damage contributes to the accelerated aging phenotypes and the reduced cancer incidence observed in the Xpd(TTD) mice, the signature of reduced energy metabolism is likely to reflect a compensatory adjustment to limit the increased genotoxic stress in these mutants. These results support a general model for premature aging in DNA repair deficient mice based on cellular responses to DNA damage that impair normal tissue homeostasis.

Abstract
A diminished capacity to maintain tissue homeostasis is a central physiological characteristic of ageing. As stem cells regulate tissue homeostasis, depletion of stem cell reserves and/or diminished stem cell function have been postulated to contribute to ageing. It has further been suggested that accumulated DNA damage could be a principal mechanism underlying age-dependent stem cell decline. We have tested these hypotheses by examining haematopoietic stem cell reserves and function with age in mice deficient in several genomic maintenance pathways including nucleotide excision repair, telomere maintenance and non-homologous end-joining. Here we show that although deficiencies in these pathways did not deplete stem cell reserves with age, stem cell functional capacity was severely affected under conditions of stress, leading to loss of reconstitution and proliferative potential, diminished self-renewal, increased apoptosis and, ultimately, functional exhaustion. Moreover, we provide evidence that endogenous DNA damage accumulates with age in wild-type stem cells. These data are consistent with DNA damage accrual being a physiological mechanism of stem cell ageing that may contribute to the diminished capacity of aged tissues to return to homeostasis after exposure to acute stress or injury.

Abstract
Xeroderma pigmentosum (XP) is a rare photosensitive and cancer-prone syndrome transmitted as an autosomal recessive trait. Most cancers developed by XP patients are basal and squamous cell carcinoma strikingly restricted to sun-exposed parts of the skin. Cells from patients with classic XP are deficient in nucleotide excision repair, a versatile biochemical mechanism for removal of ultraviolet-induced DNA lesions. Among the seven classic XP complementation groups known to date (XP-A to XP-G), XP-C is the most common one in Europe and North Africa and XP-C patients remain free of neurologic problems often seen in other XP complementation groups. This has prompted us to undertake genetic correction of XP-C fibroblasts and particularly keratinocytes, which are the most relevant cells in relation to skin cancer and have proven recently to be capable of reconstructing XP-C skin in vitro. In this study, we demonstrate that DNA repair capacity, cell survival properties, and transition from proliferative to abortive keratinocyte colonies toward UVB irradiation can be fully recovered in keratinocytes from patients with XPC transduced with a retroviral vector stably driving the expression of the wild-type XPC protein. In addition, we show that in the absence of UV, XP-C keratinocytes exhibit intrinsic cell cycle abnormalities, and beta(1)-integrin overexpression, defects that are also both fully reversed after genetic correction. Together with full correction of the defects in XP-C corrected keratinocytes, in vitro reconstruction of skin from these cells open a rational perspective to XP tissue therapy.

Abstract
Recent progress in the science of aging is driven largely by the use of model systems, ranging from yeast and nematodes to mice. These models have revealed conservation in genetic pathways that balance energy production and its damaging by-products with pathways that preserve somatic maintenance. Maintaining genome integrity has emerged as a major factor in longevity and cell viability. Here we discuss the use of mouse models with defects in genome maintenance for understanding the molecular basis of aging in humans.

Abstract
Rodent ultraviolet light (UV)-sensitive mutant cells in complementation groups (CGs) 1 and 4 normally are known for their extraordinary (approximately 80-100 x) sensitivity to mitomycin C (MMC), although some CG1 mutants with reduced MMC sensitivity were previously reported (Stefanini et al. (1987) Cytotechnology 1, 91). We report here new CG1 and CG4 mutants with only 1.6-10 x wild-type MMC sensitivity despite low unscheduled DNA synthesis (UDS) levels. Mutant UV140, in UV CG4, has approximately 3.8 x the UV sensitivity of parental line AA8, approximately 1.6 x wild-type MMC sensitivity, wild-type X-ray and ethyl methanesulfonate (EMS) sensitivity, and is only slightly (approximately 1.4 x) hypermutable to 8-azaadenine resistance by UV light. It has moderately decreased incision of UV-damaged DNA, has moderately decreased removal of (6-4) photoproducts, and is profoundly deficient in UDS after UV. After UV, it shows abnormally decreased DNA synthesis and persistently decreased RNA synthesis. In addition a cell-free extract of this mutant displays strongly reduced nucleotide excision repair synthesis using DNA treated with N-acetoxy-acetyl-amino-fluorene (AAF). The extract selectively fails to complement extracts of group 1 and 4 mutants consistent with the notion that the affected proteins, ERCC1 and ERCC4, are part of the same complex and that mutations in one subunit also affect the other component. Mutant UV212 is a CG1 mutant with approximately 3.3 x wild-type UV and approximately 5-10 x wild-type MMC sensitivity, with profoundly deficient UDS and hypermutability (approximately 5.8 x) by UV. Mutant UV201, probably in CG1, is only slightly (approximately 1.5 x) UV-sensitive and has near wild-type (1.02X) UV mutability. These unusual group 1 and 4 mutants demonstrate that the unique UV and MMC sensitivity phenotypes displayed by these groups can be separated and support the idea that they are the result of distinct repair functions of the corresponding ERCC1 and ERCC4 genes: nucleotide excision repair for UV lesions and a separate repair pathway for removal of interstrand crosslinks.

Abstract
The phenotypic consequences of a nucleotide excision repair (NER) defect in man are apparent from three distinct inborn diseases characterized by hypersensitivity of the skin to ultraviolet light and a remarkable clinical and genetic heterogeneity. These are the prototype repair syndrome, xeroderma pigmentosum (XP) (seven genetic complementation groups, designated XP-A to XP-G), Cockayne's syndrome (two groups: CS-A and CS-B) and PIBIDS, a peculiar photosensitive form of the brittle hair disease trichothiodystrophy (TTD, at least two groups of which one equivalent to XP-D). To investigate the mechanism of NER and to resolve the molecular defect in these NER deficiency diseases we have focused on the cloning and characterization of human DNA repair genes. One of the genes that we cloned is ERCC3. It specifies a chromatin binding helicase. Transfection and microinjection experiments demonstrated that mutations in ERCC3 are responsible for XP complementation group B, a very rare form of XP that is simultaneously associated with Cockayne's syndrome (CS). The ERCC3 protein was found to be part of a multiprotein complex (TFIIH) required for transcription initiation of most structural genes and for NER. This defines the additional, hitherto unknown vital function of the gene. This ERCC3 gene and several other NER genes involved in transcription initiation will be discussed.

Abstract
The RAD6 gene of the yeast Saccharomyces cerevisiae is required for DNA repair, for DNA damage-induced mutagenesis, and for sporulation, and it encodes a ubiquitin-conjugating enzyme. We have cloned the RAD6 homolog from Drosophila melanogaster and find that its encoded protein displays a very high degree of identity in amino acid sequence with the homologous RAD6 proteins from the two divergent yeasts, S. cerevisiae and Schizosaccharomyces pombe, and from human. Genetic complementation studies indicate that the Drosophila RAD6 homolog can functionally substitute for the S. cerevisiae RAD6 gene in its DNA-repair and UV-mutagenesis functions but cannot substitute in sporulation. The high degree of structural and functional conservation of RAD6 in eukaryotic evolution suggests that the various protein components involved in RAD6-dependent DNA repair and mutagenesis functions have also been conserved.

Abstract
We report on the physical ordering of genes in a relatively small area of chromosome 19, segment q13, containing the locus for myotonic dystrophy (DM), the most frequent heritable muscular dystrophy of adulthood in man. DNAs from somatic cell hybrids with der 19q products that carry a breakpoint across the muscle-specific creatine kinase (CKMM) gene were analyzed by Southern blotting using probes for CKMM, APOC2, and the repair genes ERCC1 and ERCC2. Results were combined with data from CHEF and field inversion-gel-electrophoresis separation of large-sized DNA restriction fragments to establish a map localizing both DNA-repair genes and the CKMM gene within the same 250 kb of DNA, the order being cen-CKMM-ERCC2-ERCC1-ter, with APOC2 being at more than 260 kb proximal to CKMM. Transcriptional start sites of the CKMM and DNA-repair genes are all on the telomeric side of the genes. Our results provide a framework for the construction of a larger physical map of the area, which will facilitate the search for the DM gene.
