Abstract
Cutaneous T cell lymphoma (CTCL) is a varied group of neoplasms that affects the skin. Acquired resistance against chemotherapeutic drugs and associated toxic side effects are limitations that warrant search for novel drugs against CTCL. Embelin (EMB) is a naturally occurring benzoquinone derivative that has gained attention owing to its anticancer pharmacological actions and nontoxic nature. We assessed the anticancer activity of EMB against CTCL cell lines, HuT78, and H9. EMB inhibited viability of CTCL cells in a dose-dependent manner. EMB activated extrinsic and intrinsic pathways of apoptosis as shown by the activation of initiator and executioner caspases. EMB-induced apoptosis also involved suppression of inhibitors of apoptosis, XIAP, cIAP1, and cIAP2. PARP cleavage and upregulation of pH2AX indicated DNA damage induced by EMB. In conclusion, we characterized a novel apoptosis-inducing activity of EMB against CTCL cells, implicating EMB as a potential therapeutic agent against CTCL.

Abstract
PURPOSE To evaluate the disease characteristics and survival of patients with ocular adnexal T-cell lymphoma. METHODS A retrospective, observational study of patients with a histopathological diagnosis of T-cell lymphoma of the ocular adnexa seen between 1992 and 2022. Demographic data, clinical presentation, imaging, histology, immunohistochemistry, treatment, and outcomes were reviewed. RESULTS Fifteen patients were included in the study with the mean age at diagnosis of 50 years old (range 7-85). The most common presenting symptoms were ulcerated eyelid skin lesions (40%) followed by eyelid swelling (13.3%), and lacrimal passageways obstruction (13.3%). The anaplastic large cell lymphoma (33%) and primary cutaneous T-cell lymphoma (33%) were the most diagnosed peripheral T-cell lymphoma subtypes, followed by the nasal type natural killer/T-cell lymphoma (27%) and peripheral T-cell lymphoma not otherwise specified (7%). The most prevalent stage of disease progression was stage I and stage IV (Ann Arbor classification) with seven (47%) patients each. Eight (53%) patients succumbed to the disease process of which three (37.5%) deceased in the first six months and six (75%) within the first year of diagnosis. We identified a strong statistical association between stage and disease-related death ( p = 0.003). CONCLUSIONS Peripheral T-cell lymphoma occurring in the orbit and ocular adnexa is extremely rare. Advanced stage at diagnosis leads to almost certain death from the disease despite aggressive local and systemic treatment. Early diagnosis improves the chances of survival but can be hindered by this condition's ability to simulate benign inflammatory conditions both clinically and histologically.

Abstract
Cutaneous T cell lymphomas (CTCLs) are a group of heterogeneous, life-threatening, extra-nodal and lymphoproliferative T cell neoplasms. Since chronic inflammation serves a key role in CTCL progression, curcumin, a natural pigment with proven anti-inflammatory and antineoplastic properties, as well as minimal toxicity, may be used as a therapeutic agent. In the present study, two formulations of curcumin (standard ethanolic and a Pluronic®P-123/F-127 micellar solution) were compared regarding their cytotoxic efficacy and speed of internalization in three CTCL cell lines, namely HuT-78, HH and MJ. In addition, the modulating effect of curcumin on selected proteins involved in the proliferation and progression of the disease was determined. The results indicated the superiority of the Pluronic®P-123/F-127 micellar curcumin over the standard ethanol solution in terms of cellular internalization efficiency as determined by spectrophotometric analysis. Notably, the presence of commonly used media components, such as phenol red, may interfere when interpreting the cytotoxicity of curcumin, due to their overlapping absorbance peaks. Therefore, it was concluded that phenol red-free media are superior over media with phenol red in order to correctly measure the cytotoxic efficacy and cell penetration of curcumin. Depending on the cell line, the IC50 values of micellar curcumin varied from 29.76 to 1.24 µΜ, with HH cells demonstrating the highest sensitivity. This cell line had the lowest expression levels of the Wilms' tumor-1 transcription factor. Performing western blot analyses of treated and untreated CTCL cells, selective signal transduction changes were recorded for the first time, thus making curcumin nano-formulation an attractive and prospective option with therapeutic relevance for CTCL as a rare orphan disease.

Abstract
The extracellular matrix (ECM) is a complex network of proteins and proteoglycans secreted by keratinocytes, fibroblasts and immune cells. The function of the skin ECM has expanded from being a scaffold that provides structural integrity, to a more dynamic entity that is constantly remodeled to maintain tissue homeostasis. The ECM functions as ligands for cell surface receptors such as integrins, dystroglycans, and toll-like receptors (TLRs) and regulate cellular signaling and immune cell dynamics. The ECM also acts as a sink for growth factors and cytokines, providing critical cues during epithelial morphogenesis. Dysregulation in the organization and deposition of ECMs lead to a plethora of pathophysiological conditions that are exacerbated by aberrant ECM-immune cell interactions. In this review, we focus on the interplay between ECM and immune cells in the context of skin diseases and also discuss state of the art therapies that target the key molecular players involved.

Abstract
PURPOSE Cutaneous T-cell lymphoma (CTCL) is known to have an excellent response to radiotherapy, an important treatment modality for this disease. In patients with extremity and digit involvement, the irregular surface and depth variations create difficulty in delivering a homogenous dose using electrons. We sought to evaluate photon irradiation with rice packing as tissue equivalence and determine clinical tolerance and response. MATERIALS AND METHODS Three consecutive CTCL patients with extensive lower extremity involvement including the digits were treated using external beam photon therapy with rice packing for tissue compensation. The entire foot was treated to 30-40 Gy in 2-3 Gy per fraction using 6 MV photons prescribed to the mid-plane of an indexed box filled with rice in which the foot was placed. Treatment tolerance and response were monitored with clinical evaluation. RESULTS All patients tolerated the treatment without treatment breaks. Toxicities included grade 3 erythema and desquamation with resolution within 4 weeks. No late toxicities were observed. All patients had a partial response by 4 weeks after therapy with two patients achieving a complete response. Patients reported improved functionality after treatment. No local recurrence has been observed. CONCLUSION Tissue compensation with rice packing offers a convenient, inexpensive, and reproducible method for the treatment of CTCL with highly irregular surfaces.

Abstract
PURPOSE PTEN is an essential tumour suppressor gene which encodes a phosphatase protein that antagonises the PI3K/Akt/mTOR antiapoptotic pathway. Impairment of this tumour suppressor pathway potentially becomes a causal factor for development of malignancies. This review aims to assess current understanding of mechanisms of dysfunction involving the PI3K/PTEN/Akt/mTOR pathway linked to tumorigenesis and evaluate the evidence for targeted therapy directed at this signalling axis. METHODS Relevant articles in scientific databases were identified using a combination of search terms, including "malignancies", "targeted therapy", "PTEN", and "combination therapy". These databases included Medline, Embase, Cochrane Review, Pubmed, and Scopus. RESULTS PI3K/PTEN expression is frequently deregulated in a majority of malignancies through genetic, epigenetic, and post-transcriptional modifications. This contributes to the upregulation of the PI3K/Akt/mTOR pathway which has been the focus of intense clinical studies. Targeted agents aimed at this pathway offer a novel treatment approach in a variety of haematologic malignancies and solid tumours. Compared to single-agent use, greater response rates were obtained in combination regimens, supporting further investigation of suitable drug combinations in a broad spectrum of malignancies. CONCLUSION Activation of the PI3K/PTEN/Akt/mTOR pathway is implicated both in the pathogenesis of malignancies and development of resistance to anticancer therapies. Therefore, PI3K/Akt/mTOR inhibitors are a promising therapeutic option, in association with systemic cytotoxic and biological therapies, to enable sustained clinical outcomes in cancer treatment. Therapeutic strategies could be tailored according to appropriate biomarkers and patient-specific mutation profiles to maximise benefit of combination therapies.

Abstract
Cutaneous T-cell lymphomas (CTCLs) are the most common primary skin lymphomas, which are characterized by an accumulation of malignant T cells in the skin. The early lesion resembles both clinically and histologically benign inflammatory disorders and also presents with hyperproliferative epidermis and T-cell infiltration. Despite considerable progress in understanding the molecular mechanisms involved in the malignant transformation of T cells, the causes of the morphological and histopathological features of the disease are largely unknown. We used an organotypic model of CTCL to show that malignant T cells through the secretion of galectin-1 and -3 stimulate vigorous growth of keratinocytes. In parallel, malignant T cells induce disorganized keratinocyte stratification, resembling the early hyperproliferative stage of CTCL. We also observed a loss of attachment between the epithelial and mesenchymal compartments. In addition, hyperproliferation was followed by a downregulation of differentiation markers, such as keratin 10 and involucrin, and a decrease in barrier formation. In conclusion, we provide evidence that malignant T cells orchestrate the histopathological epidermal changes seen in CTCL.

Abstract
PURPOSE CC chemokine receptor 4 (CCR4) is expressed by peripheral T-cell lymphomas (PTCLs) and is associated with poor outcomes. Mogamulizumab (KW-0761) is a defucosylated humanized anti-CCR4 antibody engineered to exert potent antibody-dependent cellular cytotoxicity. This multicenter phase II study evaluated the efficacy and safety of mogamulizumab in patients with relapsed PTCL and cutaneous T-cell lymphoma (CTCL). PATIENTS AND METHODS Mogamulizumab (1.0 mg/kg) was administered intravenously once per week for 8 weeks to patients with relapsed CCR4-positive PTCL or CTCL. The primary end point was the overall response rate, and the secondary end points included safety, progression-free survival (PFS), and overall survival (OS). RESULTS A total of 38 patients were enrolled, and 37 patients received mogamulizumab. Objective responses were noted for 13 of 37 patients (35%; 95% CI, 20% to 53%), including five patients (14%) with complete response. The median PFS was 3.0 months (95% CI, 1.6 to 4.9 months), and the median OS was not calculated. The mean maximum and trough mogamulizumab concentrations (± standard deviation) after the eighth infusion were 45.9 ± 9.3 and 29.0 ± 13.3 μg/mL, respectively. The most common adverse events were hematologic events, pyrexia, and skin disorders, all of which were reversible and manageable. CONCLUSION Mogamulizumab exhibited clinically meaningful antitumor activity in patients with relapsed PTCL and CTCL, with an acceptable toxicity profile. Further investigation of mogamulizumab for treatment of T-cell lymphoma is warranted.

Abstract
Cutaneous T cell lymphomas (CTCL) represent rare extranodal non-Hodgkin's lymphomas, which are characterised by pleomorphic skin lesions and distinct T-cell markers. CTCL is a relatively benign disease in its early stages, but survival rates decrease significantly with progression. Histone deacetylase inhibitors (HDACi) have recently emerged as a new class of targeted anticancer therapies for CTCL, which have been shown to induce growth inhibition, terminal differentiation and apoptosis in various cancers in vitro and in vivo. In addition to the intrinsic anticancer properties of HDACi, recent studies have demonstrated its ability to synergise with phototherapy. In particular, we examine the therapeutic potential of HDACi in combination with ultraviolet A (UV-A) phototherapy, employing a halogenated DNA minor groove binding ligand called UVASens as a photosensitiser. In vitro studies have demonstrated that UVASens is approximately 1000-fold more potent than current psoralens. The extreme photopotency of UVASens allows the use of lower radiation doses minimising the carcinogenic risks associated with the long-term use of phototherapy. Considering, previous findings using the photosensitiser UVASens and potential synergy of HDACi with phototherapy, it was hypothesised that HDACi will augment photochemotherapy-induced cytotoxicity in CTCL MyLa cells. The findings indicated that combinations of UVASens/UV-A photochemotherapy and HDACi significantly decreased cell viability and increased apoptosis and DNA double-strand breaks in MyLa cells.

Inhibition of histone deacetylase 3 causes replication stress in cutaneous T cell lymphoma. PLoS One 2013; 8:e68915. [PMID: 23894374 PMCID: PMC3718806 DOI: 10.1371/journal.pone.0068915] [Citation(s) in RCA: 75] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2013] [Accepted: 06/04/2013] [Indexed: 11/19/2022] Open
Abstract
Given the fundamental roles of histone deacetylases (HDACs) in the regulation of DNA repair, replication, transcription and chromatin structure, it is fitting that therapies targeting HDAC activities are now being explored as anti-cancer agents. In fact, two histone deacetylase inhibitors (HDIs), SAHA and Depsipeptide, are FDA approved for single-agent treatment of refractory cutaneous T cell lymphoma (CTCL). An important target of these HDIs, histone deacetylase 3 (HDAC3), regulates processes such as DNA repair, metabolism, and tumorigenesis through the regulation of chromatin structure and gene expression. Here we show that HDAC3 inhibition using a first in class selective inhibitor, RGFP966, resulted in decreased cell growth in CTCL cell lines due to increased apoptosis that was associated with DNA damage and impaired S phase progression. Through isolation of proteins on nascent DNA (iPOND), we found that HDAC3 was associated with chromatin and is present at and around DNA replication forks. DNA fiber labeling analysis showed that inhibition of HDAC3 resulted in a significant reduction in DNA replication fork velocity within the first hour of drug treatment. These results suggest that selective inhibition of HDAC3 could be useful in treatment of CTCL by disrupting DNA replication of the rapidly cycling tumor cells, ultimately leading to cell death.

Abstract
Differential diagnosis of cutaneous T cell lymphoma (CTCL) and severe atopic dermatitis (AD) is often difficult because of the similarity in their skin manifestations. However, such differentiation is extremely important because of the differences in remedy and prognosis. The aim of this study was to investigate new, helpful diagnostic aids for distinguishing CTCL from AD. The frequency of forkhead box protein 3(+) (FoxP3(+)) regulatory T cells (T(regs)) in cutaneous lesions was evaluated among the three populations. Serum-soluble interleukin-2 receptor (sIL-2R), immunoglobulin (Ig)E-radioimmunosorbent test, lactate dehydrogenase (LDH) and blood eosinophil count were measured in 11 CTCL patients (including three CTCL patients misdiagnosed previously with intractable AD), 10 adult AD patients and nine psoriasis patients. The frequency of T(regs) was increased significantly in cutaneous lesions of AD compared with those of CTCL. Serum IgE and LDH levels were also elevated significantly in AD compared with CTCL, whereas there were no significant differences in serum sIL-2R levels between CTCL and AD. In the three CTCL patients who were misdiagnosed with intractable AD, IgE and LDH levels were lower than in AD patients, whereas serum sIL-2R levels were as high as in AD patients and higher than in the other eight CTCL patients. The higher frequency of T(regs) in the cutaneous lesions of patients with AD than in those with CTCL and higher serum IgE and LDH levels in patients with AD than in those with CTCL might be helpful reference values for the differential diagnosis of these two diseases.

Abstract
INTRODUCTION The immediate early response gene X-1 (IEX-1) plays a pivotal role in the regulation of cell apoptosis, proliferation, differentiation and metabolism. Deregulation of IEX-1 expression has been confirmed in multiple cancers in humans, in association with either poor or better prognosis depending on the type and progression stages of the cancer. AREAS COVERED This review summarizes clinical studies of altered IEX-1 expression in ovarian, pancreatic, blood, breast and colorectal cancers, lymphoma and myeloma. The authors also outline the current understandings of the complex functions of IEX-1 gained from studies with animal models and tumor cell lines so as to help us comprehend the significance of the clinical findings. EXPERT OPINION IEX-1 holds great promise to be a valuable biomarker, either alone or in combination with other genes, for monitoring progression of some cancers. IEX-1 expression is highly sensitive to environmental cues and distinct between normal and cancer cells. However, use of IEX-1 as a biomarker remains a significant challenge because too little is understood about the mechanism underlying the diverse activities of IEX-1 and a standardized clinical assay for IEX-1 detection and validation of clinical results across different studies are still critically lacking.
