Single nucleotide polymorphisms (SNP) in repair gene DNA such as XPC gene can reduce the DNA repair capacity (DRC). Reduced DRC induce genetic instability and may increase the susceptibility to prostate cancer (PC). We conducted a case-controls study to examine the relationship between XPC Lys939Gln and XPC-PAT polymorphisms and the risk for prostate cancer in Tunisian population. Read More

Correlation of xeroderma pigmentosum complementation group F (XPF) expression with gastric cancer and prognosis was investigated. We randomly selected 76 gastric cancer patients who were admitted to the Second People's Hospital of Dezhou City and received treatment, and detected XPF expression in gastric cancer tissues (observation group) and normal gastric mucosa adjacent to tumor (control group) via immunohistochemistry. Correlation between XPF expression and clinicopathological indicators of gastric cancer was verified via single-factor Chi-square test. Read More

Ichthyosis prematurity syndrome (IPS), or ichthyosis congenita type IV, is a rare syndromic form of autosomic recessive ichthyosis caused by mutations in fatty acid transport protein 4 (FATP4), also known as SLC27A4. Patients with a disrupted FATP4 gene are usually born prematurely with thick desquamating skin and other complications, such as neonatal asphyxia, eosinophilia and elevated serum immunoglobulin E levels. Symptoms become less severe after the first months of life, evolving to non-scaly ichthyosis with follicular hyperkeratosis in adulthood (1, 2). Read More

Placental steroid sulphatase deficiency (SSD) is an X-linked inborn error of metabolism. Congenital X-linked ichthyosis (XLI) is a genetic disorder of keratinisation caused by steroid sulphatase (STS) deficiency, which results in a scaling skin condition in male infants shortly after birth. It may be associated with failed induction of labor and prolonged labor leading to cesarean delivery due to 'cervical dystocia'. Read More

A group of human mutations within the N-terminal (NT) domain of connexin 26 (Cx26) hemichannels produce aberrant channel activity, which gives rise to deafness and skin disorders, including keratitis-ichthyosis-deafness (KID) syndrome. Structural and functional studies indicate that the NT of connexin hemichannels is folded into the pore, where it plays important roles in permeability and gating. In this study, we explore the molecular basis by which N14K, an NT KID mutant, promotes gain of function. Read More

Harlequin ichthyosis is the most severe form of autosomal recessive congenital ichthyoses. So far, there are only a few reports of prenatal diagnosis in the literature, as prenatal sonographic features are quite subtle. We report a case of prenatal diagnosis of Harlequin ichthyosis on third-trimester sonographic examination in a consanguineous couple with no history of the disease and describe its characteristic sonographic features.

Xeroderma Pigmentosum (XP) encompasses a group of rare diseases characterised in most cases by nucleotide excision repair (NER) malfunction, resulting in an increased sensitivity to ultraviolet radiation in affected individuals. Approximately 25-30% of XP patients present with neurological symptoms, such as sensorineural deafness, mental deterioration, and ataxia. Although it is known that dysfunctional DNA repair is the primary pathogenesis in XP, growing evidence suggests that mitochondrial pathophysiology may also occur. Read More

The corneocyte lipid envelope (CLE), a monolayer of ϖ-hydroxyceramides, whose function(s) remain(s) uncertain, is absent in autosomal recessive congenital ichthyoses (ARCI) with mutations in enzymes that regulate epidermal lipid synthesis. Secreted lipids fail to transform into lamellar membranes in certain ARCI epidermis, suggesting the CLE provides a scaffold for the extracellular lamellae. But since cornified envelopes (CEs) are attenuated in these ARCI, the CLE may also provide a scaffold for subjacent CE formation, evidenced by restoration of CEs after CLE 'rescue. Read More

Chanarin Dorfman syndrome is a multisystem, very rare, autosomal recessive lipid storage disorder, characterized by the accumulation of lipid vacuoles in neutrophils, and was first described by Dorfman in 1974. Due to a mutation in the ABHD5 gene of the short arm of chromosome 3, lipid is stored in the granulocytes at various sites in the human body, such as the muscle, liver, eye, ear, central nervous system, and bone marrow. Clinically, the disease is presented with ichthyosis, hearing loss, hepatomegaly, splenomegaly, cirrhosis, cataract, keratopathy, myopathy, and mental retardation. Read More

Calcium (Ca) is an essential regulator for a large number of cellular functions in various tissues and organs, and small disturbances of Ca homeostasis can severely compromise normal physiology. Intracellular Ca balance is mainly controlled by the reticular Ca sensor STIM1 and the plasma membrane Ca channel ORAI1 through a mechanism known as store-operated Ca entry (SOCE). Gain-of-function mutations in STIM1 or ORAI1 cause excessive extracellular Ca influx, resulting in tubular aggregate myopathy (TAM) and Stormorken syndrome (STRMK). Read More

Xeroderma pigmentosum (XP) is a form of general dermatosis characterised by photo-induced cutaneous-ocular impairment and by skin cancers. In addition to these signs, there may also be neurological involvement. This disease is related to a defect in genes within the nucleotide excision repair system for the first seven genetic groups (A-G), and to an abnormality in transcription groups for the eighth group (xeroderma pigmentosum variant - XPV).

The 5'-3' structure-specific endonuclease ERCC1/XPF (Excision Repair Cross-Complementation Group 1/Xeroderma Pigmentosum group F) plays critical roles in the repair of cisplatin-induced DNA damage. As such, it has been identified as a potential pharmacological target for enhancing clinical response to platinum-based chemotherapy. The goal of this study was to follow up on our previous identification of the compound NSC143099 as a potent inhibitor of ERCC1/XPF activity by performing an in silico screen to identify structural analogues that could inhibit ERCC1/XPF activity in vitro and in vivo.

The role of epidermal proteolysis in overdesquamation was revealed in Netherton syndrome, a rare ichthyosis due to genetic deficiency of the LEKTI inhibitor of serine proteases. Recently, we developed activography, a new histochemical method, to spatially localize and semi-quantitatively assess proteolytic activities using activity-based probes. Activography provides specificity and versatility compared to in situ zymography, the only available method to determine enzymatic activities in tissue biopsies. Read More

Autosomal recessive congenital ichthyosis (ARCI) is a group of monogenic skin disorders caused by mutations in any of at least 12 different genes, many of which are involved in the epidermal synthesis of ω-O-acylceramides (acylCer). AcylCer are essential precursors of the corneocyte lipid envelope crosslinked by transglutaminase-1 (TGm-1), or a yet unidentified enzyme, for normal skin barrier formation. We hypothesized that inactivating TGM1 mutations will lead to a compensatory overexpression of the transcripts involved in skin barrier repair, including many other ARCI-causing genes. Read More

Mutations in the genes coding for patatin-like phospholipase domain-containing 1 (PNPLA1) and α/β-hydrolase domain-containing 5 (ABHD5), also known as comparative gene identification 58, are causative for ichthyosis, a severe skin barrier disorder. Individuals with mutations in either of these genes show a defect in epidermal ω--acylceramide (AcylCer) biosynthesis, suggesting that PNPLA1 and ABHD5 act in the same metabolic pathway. In this report, we identified ABHD5 as a coactivator of PNPLA1 that stimulates the esterification of ω-hydroxy ceramides with linoleic acid for AcylCer biosynthesis. Read More

Clinical features of TTD consist of variable neuroectodermal symptoms including ichthyosis, nail abnormalities, mental retardation, short stature, decreased fertility and proneness to infections. Approximately half of the reported patients with TTD have clinical and cellular photosensitivity associated with mutations in three subunits (ERCC3, ERCC2, GTF2H5) of the basal transcription factor TFHII, which is involved in transcription and nucleotide excision repair.
