Tiejun Zhang, Di Zhang
Although numerous approaches have been proposed to discern driver from passenger, identification of driver genes remains a critical challenge in the cancer genomics field. Driver genes with low mutated frequency tend to be filtered in cancer research. In addition, the accumulation of different omics data necessitates the development of algorithmic frameworks for nominating putative driver genes. In this study, we presented a novel framework to identify driver genes through integrating multi-omics data such as somatic mutation, gene expression, and copy number alterations...

Invasive cancer cells develop small actin-based protrusions called invadopodia, which perform a primordial role in metastasis and extracellular matrix remodelling. Neural Wiskott-Aldrich syndrome protein (N-WASp) is a scaffold protein which can directly bind to actin monomers and Arp2/3 and is a crucial player in the formation of an invadopodium precursor. Expression modulation has pointed to an important role for N-WASp in invadopodium formation but the role of its C-terminal VCA domain in this process remains unknown...

INTRODUCTION: With advanced-stage head and neck cancers, patients may develop large and/or complex wounds despite multiple reconstruction attempts. Wound coverage may require novel approaches to palliate the patient. METHOD: We present the case of a 56-year-old female with advanced squamous cell carcinoma of the scalp and skull who required multiple surgical interventions. Despite our best reconstructive efforts, the patient subsequently developed scalp infection and sepsis, necessitating further debridement for source control...

Syringocystadenoma papilliferum (SP) is a rare benign hamartomatous malformation of skin which arises from apocrine or eccrine sweat glands. Skin of the head and neck is the usual site for this but rarely involves the eyelids. It is also called as a childhood tumor since it usually appears at birth or during puberty. The diagnosis is confirmed on histopathological examination after surgical excision. We are first to report a case of SP involving the caruncle in an elderly female.

Darier disease (DD), also known as keratosis follicularis or dyskeratosis follicularis, is a rare autosomal dominant genodermatosis with high penetrance and variable expressivity. It is caused by mutations of ATP2A2 gene which encodes the sarco/endoplasmic reticulum Ca(2+) ATPase isoform 2. It is clinically manifested by hyperkeratotic papules primarily affecting seborrheic areas on the head, neck and thorax, with less frequent involvement of the oral mucosa. When oral manifestations are present, they primarily affect the palatal and alveolar mucosa, are usually asymptomatic and are discovered in routine dental examination...

Oral squamous cell carcinoma (OSCC) is the most common type of oral neoplasm, accounting for over 90% of all oral malignancies and 38% of head and neck tumors. Worldwide, OSCC is the eighth most common human cancer, with more than 500,000 new cases being diagnosed every year with a fairly onerous prognosis, encouraging further research on factors that might modify disease outcome. Genetic and/or environmental risk factors associated with the development of oral cancer have been sufficiently understood (smoking, alcohol, betel, diet, living habits, etc...

Checkpoint inhibitors have demonstrated efficacy in patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). However, the majority of patients do not benefit from these agents. To improve the efficacy of checkpoint inhibitors, intratumoral (i.t.) injection with innate immune activators, TLR7 and TLR9 agonists, were tested along with programmed death-1 receptor (PD-1) blockade. The combination therapy suppressed tumor growth at the primary injected and distant sites in human papillomavirus-negative (HPV-negative) SCC7 and MOC1, and HPV-positive MEER syngeneic mouse models...
