Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

Phenotype diversity in familial cylindromatosis: a frameshift mutation in the tumor suppressor gene CYLD underlies different tumors of skin appendages. (1/25)

Familial cylindromatosis (turban tumor syndrome; Brooke-Spiegler syndrome) (OMIM numbers 123850, 132700, 313100, and 605041) is a rare autosomal dominantly inherited tumor syndrome. The disorder can present with cutaneous adnexal tumors such as cylindromas, trichoepitheliomas, and spiradenomas, and tumors preferably develop in hairy areas of the body such as head and neck. In affected families, mutations have been demonstrated in the CYLD gene located on chromosome 16q12-13 and reveal the characteristic attributes of a tumor suppressor. Here, we studied familial cylindromatosis in a multigeneration family of German origin. Clinically, some individuals only revealed discrete small skin-colored tumors localized in the nasolabial region whereas one family member showed expansion of multiple big tumors on the trunk and in a turban-like fashion on the scalp. Histologically, cylindromas as well as epithelioma adenoides cysticum were found. We detected a frameshift mutation in the CYLD gene, designated 2253delG, underlying the disorder and were able to show that a single mutation can result in distinct clinical and histologic expression in familial cylindromatosis. The reasons for different expression patterns of the same genetic defect in this disease remain elusive, however. Identification of mutations in the CYLD gene enable us to rapidly confirm putative diagnoses on the genetic level and to provide affected families with genetic counseling.  (+info)

Piloleiomyoma--a report of five cases. (2/25)

Piloleiomyomas are uncommon smooth muscle neoplasms of the skin with a few reproted cases in Indian literature (1,2,3,4,5). They are often misdiagnosed clinically. A correct biopsy report is important because patients may have to be managed medically since surgery is associated with a high rate of recurrence. The classical histologic findings, and Masson's stain to confirm the smooth muscle origin aids in the correct diagnosis.  (+info)

Squamous cell carcinoma in situ arising in mature cystic teratoma. (3/25)

Mature cystic teratomas of ovary are common tumors. A few may exhibit malignant degeneration, most of these being invasive squamous cell carcinoma. We report a rare case of pure squamous cell carcinoma in situ in benign cystic teratoma.  (+info)

A novel missense mutation in CYLD in a family with Brooke-Spiegler syndrome. (4/25)

Brooke-Spiegler syndrome (BSS, familial cylindromatosis or turban tumor syndrome) is an inherited disease characterized by neoplasms of the skin appendages such as cylindroma, trichoepithelioma, and spiradenoma. The disease has been mapped to 16q12-13, and mutations in the CYLD gene have been identified in families with this disorder. Of interest, multiple familial trichoepithelioma (MFT) has been described as a distinct disorder characterized by the familial occurrence of trichoepitheliomas. MFT has been mapped to 9p21; however, to date a candidate gene has not been identified. In this report, we describe a four-generation family with BSS presenting predominantly with trichoepitheliomas (resembling MFT phenotype). We identified a novel missense mutation in the CYLD gene, designated E474G, in the affected individuals of this family. Our findings exemplify clinical heterogeneity within BSS and extend the body of evidence that mutations in CYLD are implicated in this disease. Although not conclusive, these findings suggest that BSS and MFT may represent a single entity.  (+info)

Mutations in the CYLD gene in Brooke-Spiegler syndrome, familial cylindromatosis, and multiple familial trichoepithelioma: lack of genotype-phenotype correlation. (5/25)

Brooke-Spiegler syndrome (BSS), familial cylindromatosis (FC), and multiple familial trichoepithelioma (MFT), originally described as distinct entities, share overlapping clinical findings. Patients with BSS are predisposed to multiple skin appendage tumors such as cylindroma, trichoepithelioma, and spiradenoma. FC, however, is characterized by cylindromas and MFT by trichoepitheliomas as the only tumor type. These disorders have recently been associated with mutations in the CYLD gene. In this report, we describe three families with BSS, one with FC, and two with MFT phenotypes associated with novel and recurrent mutations in CYLD. We provide evidence that these disorders represent phenotypic variation of a single entity and lack genotype-phenotype correlation.  (+info)

Sex steroid hormone receptors in human skin appendage and its neoplasms. (6/25)

Sex steroids have been postulated to influence pathophysiology of human skin through various skin appendages. The presence of sex steroid receptors has been also reported in adnexal tumors but its details still remained unknown. Therefore, in this study, we immunolocalized sex steroid receptor protein (estrogen receptor (ER)alpha, ERbeta, progesterone receptor (PR)A, PRB and androgen receptor (AR)) in 23 cases of non-pathological skin (male: 10, female: 13) and in 50 cases of skin adnexal tumors (male 24, female 26; 38 benign and 12 malignant). ERalpha immunoreactivity was detected exclusively in basal cells of sebaceous glands of non-pathological skin. AR and PRB immunoreactivity was detected in both differentiated and basal cells of sebaceous gland. AR and ERbeta immunoreactivity was also detected in sebaceous and eccrine sweat glands but not in outer root sheath of hair follicles. In sebaceous gland neoplasms, the number of ERalpha positive cases was significantly lower in skin appendage neoplasms than non-pathological skin. ERbeta immunoreactivity was not detected in any of sebaceous gland neoplasms examined. There were no significant differences in PRA, PRB and AR immunoreactivity between non-pathological sebaceous gland and its neoplasm. In sweat gland neoplasms, the number of AR positive cases was significantly lower in benign neoplasms than their non-pathological counterpart. Therefore sex steroids are considered to play important roles in regulation of non-pathological skin appendage function and pathogenesis and/or development of its neoplasm. In addition, the status of the great majority of sex steroid hormone receptors was maintained throughout the process of neoplastic transformation of skin appendages, except for AR and ERalpha in sweat and sebaceous gland neoplasms.  (+info)

Genetics of skin appendage neoplasms and related syndromes. (7/25)

In the past decade the molecular basis of many inherited syndromes has been unravelled. This article reviews the clinical and genetic aspects of inherited syndromes that are characterised by skin appendage neoplasms, including Cowden syndrome, Birt-Hogg-Dube syndrome, naevoid basal cell carcinoma syndrome, generalised basaloid follicular hamartoma syndrome, Bazex syndrome, Brooke-Spiegler syndrome, familial cylindromatosis, multiple familial trichoepitheliomas, and Muir-Torre syndrome.  (+info)

Canine cutaneous clear cell adnexal carcinoma: histopathology, immunohistochemistry, and biologic behavior of 26 cases. (8/25)

Thirty tumors including 27 distinctive cutaneous neoplasms and 3 metastatic tumors from 26 dogs were collected from diagnostic submissions to 3 laboratories. Characteristic histopathologic features included location in the subcutis or dermis (or both); lobular, nodular, and nest-like architecture; and a component of epithelioid cells with clear cytoplasm. Additional features present in most cases included follicular dermal papilla-like structures, low mitotic index, nuclear pleomorphism, necrosis, and mineralization. Cytoplasmic periodic acid Schiff-positivity, which was abolished by pretreatment with diastase, indicated the presence of glycogen in all cases. The oil red O stain did not demonstrate cytoplasmic lipid. Melanin granules, accentuated by the Fontana-Masson method, were observed infrequently. A sparsely cellular mucinous stroma and stromal cartilaginous differentiation were uncommon. By immunohistochemistry, neoplastic cells stained positively for cytokeratin (29 of 29), vimentin (28 of 28), S-100 protein (24 of 29), and melan A (8 of 12); results were negative for smooth muscle actin and calponin in all cases. Clinical follow-up information was obtained on all 26 dogs. One tumor recurred, 1 metastasized to a regional lymph node, and 1 metastasized to regional lymph nodes twice. In another case, possible pulmonary metastasis was noted radiographically. The findings are consistent with a poorly differentiated, low-grade, adnexal carcinoma of the skin. Similar canine cutaneous neoplasms have been reported as "clear-cell hidradenocarcinoma" and "follicular stem cell carcinoma." The authors propose the designation "cutaneous clear cell adnexal carcinoma."  (+info)

Multiple familial trichoepithelioma (also known as Brooke-Spiegler syndrome and epithelioma adenoides cysticum) is a cutaneous condition characterized by multiple cystic and solid nodules appearing on the face. The classification of this syndrome is difficult. Three conditions are known to be caused by mutations in the CYLD gene: Brooke-Spiegler syndrome, multiple familial trichoepithelioma, and familial cylindromatosis. Clinically, these are distinct, but appear to arise from mutations in the same gene. Types include: Brooke-Spiegler syndrome is a condition where multiple skin tumors develop from skin structures. Tumors commonly occurring in this syndrome include spiradenomas, trichoepitheliomas, and cylindromas. The tumors are generally benign, but may become malignant. Affected individuals are also at increased risk of developing tumors in tissues other than skin - particularly benign or malignant tumors of the salivary glands. Tumours in Brooke-Spiegler typically appear in early adulthood ...
Microcystic adnexal carcinoma is a rare type of cancer that usually develops in areas of the body where sweat is produced (sweat glands). The largest of these sweat-producing sites and also the most common location where microcystic adnexal carcinoma develops is the central face. The cancer forms when a change (mutation) in DNA causes certain cells to grow out of control, sometimes forming a lump or a tumor. Microcystic adnexal carcinoma may also occur in the general head and neck regions. Some of these cancerous cells can break off and spread (metastasize) to other parts of the body and grow there.. Microcystic adnexal carcinoma most commonly occurs in adults between the ages of 40 and 60, though it can appear in all age groups. Factors that may increase the risk of developing microcystic adnexal carcinoma include excess exposure to sunlight, sunburn, and a family history of skin cancer. The most common symptoms of microcystic adnexal carcinoma include redness, inflammation, and irritation of ...
Multiple familial trichoepithelioma can be caused by mutations in the CYLD gene. This gene provides instructions for making a protein that helps regulate nuclear factor-kappa-B. Nuclear factor-kappa-B is a group of related proteins that help protect cells from self-destruction (apoptosis) in response to certain signals. In regulating the action of nuclear factor-kappa-B, the CYLD protein allows cells to respond properly to signals to self-destruct when appropriate, such as when the cells become abnormal. By this mechanism, the CYLD protein acts as a tumor suppressor, which means that it helps prevent cells from growing and dividing too fast or in an uncontrolled way.. People with CYLD-related multiple familial trichoepithelioma are born with a mutation in one of the two copies of the CYLD gene in each cell. This mutation prevents the cell from making functional CYLD protein from the altered copy of the gene. However, enough protein is usually produced from the other, normal copy of the gene to ...

CYLD is a negative regulator of TRAF2 and NF-kappa B signaling pathway. CYLD has a deubiquitinating activity that is directed towards non-Lys48-linked polyubiquitin chains. Defects in CYLD are the cause of familial cylindromatosis, a highly tumor type-specific disorder ...
CYLD is a tumour-suppressor gene that is mutated in a benign skin tumour syndrome called cylindromatosis. The CYLD gene product is a deubiquitinating enzyme that was shown to regulate cell proliferation, cell survival and inflammatory responses, mainly through inhibiting NF-kappaB signalling. Here we show that CYLD controls cell growth and division at the G(1)/S-phase as well as cytokinesis by associating with alpha-tubulin and microtubules through its CAP-Gly domains. Translocation of activated CYLD to the perinuclear region of the cell is achieved by an inhibitory interaction of CYLD with histone deacetylase-6 (HDAC6) leading to an increase in the levels of acetylated alpha-tubulin around the nucleus. This facilitates the interaction of CYLD with Bcl-3, leading to a significant delay in the G(1)-to-S-phase transition. Finally, CYLD also interacts with HDAC6 in the midbody where it regulates the rate of cytokinesis in a deubiquitinase-independent manner. Altogether these results identify a ...

Protein modification by the conjugation of ubiquitin moieties-ubiquitination-plays a major part in many biological processes, including cell cycle and apoptosis1. The enzymes that mediate ubiquitin-conjugation have been well-studied, but much less is known about the ubiquitin-specific proteases that mediate de-ubiquitination of cellular substrates2,3. To study this gene family, we designed a collection of RNA interference vectors to suppress 50 human de-ubiquitinating enzymes, and used these vectors to identify de-ubiquitinating enzymes in cancer-relevant pathways. We report here that inhibition of one of these enzymes, the familial cylindromatosis tumour suppressor gene (CYLD)4, having no known function, enhances activation of the transcription factor NF-κB. We show that CYLD binds to the NEMO (also known as IKKγ) component of the IκB kinase (IKK) complex, and appears to regulate its activity through de-ubiquitination of TRAF2, as TRAF2 ubiquitination can be modulated by CYLD. Inhibition of CYLD
The mechanism by which Wnt receptors transduce signals to activate downstream beta-catenin-mediated target gene transcription remains incompletely understood but involves Frizzled (Fz) receptor-mediated plasma membrane recruitment and activation of the cytoplasmic effector Dishevelled (Dvl). Here, we identify the deubiquitinating enzyme CYLD, the familial cylindromatosis tumor suppressor gene, as a negative regulator of proximal events in Wnt/beta-catenin signaling. Depletion of CYLD from cultured cells markedly enhances Wnt-induced accumulation of beta-catenin and target gene activation. Moreover, we demonstrate hyperactive Wnt signaling in human cylindroma skin tumors that arise from mutations in CYLD. At the molecular level, CYLD interacts with and regulates K63-linked ubiquitination of Dvl. Enhanced ubiquitination of the polymerization-prone DIX domain in CYLD-deficient cells positively links to the signaling activity of Dvl. Together, our results argue that loss of CYLD instigates tumor growth in

Patterns form with the break of homogeneity and lead to the emergence of new structure or arrangement. There are different physiological and pathological mechanisms that lead to the formation of patterns. Here, we first introduce the basics of pattern formation and their possible biological basis. We then discuss different categories of skin patterns and their potential underlying molecular mechanisms. Some patterns, such as the lines of Blaschko and Naevus, are based on cell lineage and genetic mosaicism. Other patterns, such as regionally specific skin appendages, can be set by distinct combinatorial molecular codes, which in turn may be set by morphogenetic gradients. There are also some patterns, such as the arrangement of hair follicles (hair whorls) and fingerprints, which involve genetics as well as stochastic epigenetic events based on physiochemical principles. Many appendage primordia are laid out in developmental waves. In the adult, some patterns, such as those involving cycling hair ...

To the Editor:. Misago et al1 have recently published 6 cases of infundibular (follicular) and 2 examples of infundibulocystic squamous cell carcinoma and have redefined the original criteria for both follicular squamous cell carcinoma and infundibulocystic squamous cell carcinoma.2,3 They propose that the term infundibular squamous cell carcinoma was synonymous with follicular squamous cell carcinoma, and infundibulocystic carcinoma was a distinctive tumor sharing features with microcystic adnexal carcinoma.. In the initial description of 16 examples of follicular squamous cell carcinoma by Diaz-Cascajo et al,2 these squamous cell carcinomas arose in follicles and formed nodular tumors that replaced the follicles but did not demonstrate follicular differentiation even when the tumor infiltrated the surrounding tissue. From a clinical perspective, follicular squamous cell carcinomas in the original study were described as dermal nodules that did not resemble keratoacanthoma and were diagnosed as ...
Less Common Skin Cancers. Merkel Cell Carcinoma is a rare and aggressive form of skin cancer. It arises from Merkel cells in the lower part of the epidermis. Merkel cells are similar to nerve cells and give the skin touch sensation. Treatment involves a team approach from physicians with significant experience with the disease.. Atypical Fibroxanthoma is thought to arise from the dermis, which is deeper than the epidermis, the source of most other skin cancers. It classically appears on the face or scalp as a reddish, sometimes glistening plaque (broad, raised area on the skin).. Microcystic Adnexal Carcinoma is thought to be derived from cells that produce the adnexal structures, such as hair follicles and sweat glands in the skin. It classically occurs on the face. It may have a deceivingly benign appearance and may be mistaken for a common melanocytic nevus (mole ...
Microcystic adnexal carcinoma (MAC) is a low-grade malignant tumor of the skin. Histologically, this tumor shows a biphasic pattern, with cords and nests of basaloid cells, as well as keratin horn cysts. This biphasic histological appearance has been interpreted by some authors as a sign of double eccrine and folliculosebaceous-apocrine differentiation, whereas some other authors defend a solely eccrine differentiation. In this context, sebaceous differentiation in MAC would support the first option. However, there are only 3 cases of MAC with sebaceous differentiation in the literature, and all of them were reported before adipophilin was available, which in the appropriate context (eg, testing clear cells for sebaceous vs eccrine differentiation) is very useful ...
Skin appendages (or adnexa) are skin-associated structures that serve a particular function including sensation, contractility, lubrication and heat loss. In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can be sweat secreted with strong odour (apocrine) or with a faint odour (eccrine)) and nails (protection). Skin appendages are derived from the skin, and are usually adjacent to it. Types of Appendages include hair, glands, and nails. Sweat Glands are distributed all over the body except nipples and outer genitals. Although the nipples do have the mammary glands, these are known as modified sweat glands. Sebaceous Glands are typically found in the opening shaft of hair. They are not on the palms of the hands or the soles of the feet. These glands secret an antibacterial moisture ...

CYLD is a deubiquitination enzyme that regulates different cellular processes, such as cell proliferation and cell survival. Mutation and loss of heterozygosity of the CYLD gene causes development of cylindromatosis, a benign tumour originating from the skin. Our study shows that CYLD expression is dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans. Reduced CYLD expression in basal cell carcinoma was mediated by GLI1-dependent activation of the transcriptional repressor Snail. Inhibition of GLI1 restored the CYLD expression-mediated Snail signaling pathway, and caused a significant delay in the G1 to S phase transition, as well as proliferation. Our data suggest that GLI1-mediated suppression of CYLD has a significant role in basal cell carcinoma progression.

Background: Skin Adnexal Tumours (SATs ) are large and divergent group of tumours which are classified based on their appendageal differentiation into eccrine,follicular,sebaceous and apocrine.They pose daunting diagnostic challenges to both clinicians and pathologists alike.This study aims to evaluate the histopathological charecterestics of skin adnexal neoplasms and correlate with their clinical profile.Methods : This is a retrospective study of skin adnexal tumours (28 cases) diagnosed on histopathological examination over a period of two years .( January 2014 to December 2015 ).Results: Skin adnexal tumours are uncommon lesions with an incidence of 0.27%.These tumours were common in the 51 to 60 age group and showed a female preponderance. Head and neck region particularly the scalp was commonly involved. Benign tumours were more common (78.6% ) than the malignant ones (21.4%). .Sweat gland tumours constituted the largest group (61%) followed by hair follicle tumours (21%)and sebaceous ...
This study aims to evaluate a new ointment to treat an inherited skin tumour condition called cylindromatosis. Patients from families with this condition carry an error in their DNA (CYLD mutation) that results in the development of multiple skin tumours on the face, scalp and trunk. These tumours are disfiguring, can be painful, and may ulcerate and bleed. Surgery is the only available treatment, and up to 1 in 4 patients with this condition undergo removal of their entire scalp to manage this condition. We have recently discovered an abnormal signal in the tumour cells called TRK. This signal is recognised to give tumour cells the ability to survive, and in laboratory tests blocking it with drugs called TRK inhibitors results in the tumour cells dying. We propose a study of an ointment form of TRK inhibitor as a means to reduce tumour growth in these patients. We have partnered with a drug company (Creabilis) who have already produced this ointment (called CT327) for trials in skin conditions. ...

Growing evidence in clinical studies suggests that ubiquitin systems are greatly related to the progression of atherosclerosis, particularly in relation to inflammation and cell proliferation. However, there were few reports referred to molecular mechanisms of vascular remodeling related to ubiquitin systems. NF-κB is an important transcriptional factor which plays central roles in pathogenesis of atherosclerosis. Thus, in this study, we focused on CYLD which is a NF-κB-related deubiquitinating enzyme and may be a therapeutic target of tumor in cancer research. From Northern blot and immunohistology, CYLD was endogenously expressed in vascular endothelial cells (EC) and smooth muscle cells (VSMC). Interestingly, the treatment of TNF-α significantly increased CYLD expression in EC and VSMC. CYLD was markedly induced in the neointima of the balloon-injured carotid arteries, and was also present in atherosclerotic lesions from human carotid arteries. Thus, the expression of CYLD could be ...

The skin is the largest organ of the human body, comprising approximately 17% of the body weight. An average adult would have a skin total surface area of around 1.7 square meters. The thickness of the skin varies depending on the site where it resides, ranging from 3mm to 6mm. The skin is the most visible and exposed organ of the body, and hence it is the first line of defense of the body against the harsh environment.. The structure of the skin comprises of three main layers, namely the epidermis, the dermis and the hypodermis. There are also skin appendages that play their own respective roles in the skin. Each make-up of each layer will be described below.. EPIDERMIS. The epidermis is the most dynamic layer among all the layers of the skin. Despite being the thinnest layer, it is actually the most important layer among all. The epidermis consists of 5 sub-layers, that will be listed below:.

Results: MCT comprised 230 (57.6%) out of total 399 cases of ovarian neoplasms. The age range of the patients was 8-74 years. The sizes of the tumors ranged from 2.5-20cm. 12% of the cases were bilateral. Ischemic modifications, presumably due to torsion, were noted in 10% of the cases, mostly in tumors larger than 10cm. None of the tumors of less than 5cm presented with signs of torsion. Malignant transformation was present in seven (3%) cases and was seen especially in older patients and in larger tumors. Squamous cell carcinoma was the most common malignant tumor seen in five cases. One case was a mixed germ cell tumor with components of MCT and yolk sac tumor. ...
Discussion Mature cystic teratoma (dermoid cysts), accounts for approximately 25% of all ovarian tumors. They are unilateral in 88% of the cases and present with symptoms related to the mass lesion. They contain a varied mixture of ectodermal, mesodermal and endodermal structures distributed in an organized fashion.[1] The first description of pneumatosis cystoides-like appearance in a mature cystic teratoma was given by Maudsley and Zakhour in a 29 year old primigravida in 1988.[2] Subsequently, two case studies with 13 and 7 cases respectively have been reported.[34] These multicystic structures have been variably called as sieve-like areas and Pneumatosis cystoides-like appearances by various authors.[234] The multicystic structures can occur in any age group, but they are generally found in tumors from older patients.[5] Maudsley and Zakhour suggested these cysts to be gas cysts, as on routine staining and immunohistochemistry neither cyst contents, nor endothelial lining were identified.[2] ...

Full Text - CYLD is a deubiquitinating enzyme known for its role as a tumor suppressor whose mutation leads to skin appendages tumors and other cancers. In this manuscript we report that the tumor suppressor CYLD, similarly to other renowned tumor suppressor genes, protects from premature aging and cancer. We have generated transgenic mice expressing the mutant CYLDC/S protein, lacking its deubiquitinase function, under the control of the keratin 5 promoter, the K5-CYLDC/S mice. These mice express the transgene in different organs, including those considered to be more susceptible to aging, such as skin and thymus. Our results show that K5-CYLDC/S mice exhibit epidermal, hair follicle, and sebaceous gland alterations; and, importantly, they show signs of premature aging from an early age. Typically, 3-month-old K5-CYLDC/S mice exhibit a phenotype characterized by alopecia and kyphosis, and, the histological examination reveals that transgenic mice show signs
cyld displays a dominant genetic linkage to multiple types of cutaneous adnexal tumors that often develop in bulky clusters in the head, neck, trunk, and pubic areas (10, 37). Although predominantly benign (10), these tumors are painful and disfiguring, can undergo malignant transformation with metastasis over time, and eventually lead to mortality (38-41). Thus, the malignant features of the tumors developed on K14-CYLDm transgenic mice are in line with the clinical manifestations seen in patients. Our transgenic tumor models allowed us to define JNK/AP1 signaling cascade as a key regulator in CYLDm-driven epidermal malignancy.. Cyld loss of function is not only relevant to cutaneous adnexal tumors but also to many other cancers including SCC (22,42). It is worth noting that cyld−/− mice are sensitive to chemically induced carcinogenesis, but the tumors developed on these mice are not more malignant than those of WT mice (22). We predict that the differential tumor growth phenotypes ...

The epidermis and dermis are separated by the basement membrane zone. Anchoring fibrils connect these two layers. The dermis consists of a superficial thin layer called the papillary dermis and a deep, dense layer called the reticular dermis. The primary cell of the dermis is the fibroblast that produces the collagen, elastic fibers, and ground substance that compose the bulk of the dermis. Inflammatory cells migrate through the ground substance beneath the dermis, a large plexus of arterioles and venules called the subdermal plexus. This plexus further branches into superficial smaller vessels called the papillary plexus. The skin appendages, sebaceous glands, sweat glands, and hair follicles all lie within the dermis. ...
Purpose: The hypermetabolic nature of cancer cells, especially their increased reliance on aerobic glycolysis which has been associated with more aggressive phenotype, is considered metabolic hallmarks of cancer cells including oral squamous cell carcinoma (OSCC) cells. However, its precise mechanisms remain unknown. Cylindromatosis (CYLD) is recognized as a tumor suppressor gene whereas little is available about its impact on cancer progression. Our unpublished data showed that lower CYLD expression was associated with poor prognosis in OSCC patients. The objective of our study was to address specific contributions of CYLD to the signature metabolic features of OSCC cells.. Materials and methods: We determined the level of glucose consumption as well as lactate production to evaluate the effects of CYLD knockdown by siRNA on aerobic glycolysis in human OSCC cell lines. In addition, we measured extracellular acidification and oxygen consumption rates in OSCC cells by using XF Extracellular Flux ...
