Aims: Oral squamous cell carcinoma (OSCC) primarily occurs in older age group. However, in the recent years, incidence of oral cancer in young people has been on rise worldwide. Towards this end, we sought to analyze the clinical and histopathological characteristics of OSCC in patients less than 45 years of age.
Materials And Methods: The clinical and histological features of patients diagnosed with squamous cell carcinoma of the oral cavity at two hospitals in the coastal Karnataka region of South India between 1996-2012 were reviewed. The tabulation and descriptive statistics of the study were carried out.
Results: A total of 420 patients were treated for OSCC in the 17-year period (1996-2012), of which 86 (20.5 %) patients were under 45 years of age. The most common site of involvement among the young was tongue (29.07%) and buccal mucosa (27.9%) respectively. A total of 47 (54.65%) patients were either habitual chewers, smokers, or alcoholics. Pathological grading of cases classified tumors into well differentiated (34.88%), moderately differentiated (46.51%) and poorly differentiated (4.65%).
Conclusions: The data from this study reveals that a significant proportion of the OSCC cases are observed in patients of 45 years or younger. Additionally, our study also indicated an increase in the usage of tobacco and pan chewing in young adults in comparison to older individuals in the two hospitals of South India. The data obtained from this analysis emphasizes the need for screening programs that are tailor-made for individuals at high risk of developing oral cancer and warrants tobacco awareness programs in the community.

Background: Calretinin is a 29 kilodalton (KDa) calcium-binding protein that is expressed in normal and tumoral tissues. The expression of calretinin has been shown in the dental epithelium during odontogenesis and in different odontogenic cysts and tumors such as ameloblastoma. Since the epithelium of calcifying odontogenic cyst (COC) is similar to ameloblastoma and in both lesions, an arrangement of loose cells similar to stellate reticulum is seen, we aimed to investigate the comparative expression of calretinin in COC and ameloblastoma.

Background: The increased apoptosis of bile duct epithelial cells (BECs) due to some damage factors is considered the initiating factor in the occurrence and progression of biliary atresia (BA). Vitamin D receptor (VDR) is thought to play a crucial role in maintaining the intrinsic immune balance and integrity of bile duct epithelial cells (BECs). To investigate the role of VDRs in the pathogenesis and progression of BA using in vitro and in vivo models.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

To meet the requirements of the biopharmaceutical industry, improving the yield of recombination therapeutic protein (RTP) from Chinese hamster ovary (CHO) cells is necessary. The human cytomegalovirus (CMV) promoter is widely used for RTP expression in CHO cells. To further improve RTP production, we truncated the human CMV intron and further evaluated the effect of four synthetic introns, including ctEF-1α first, EF-1α first, chimeric, and β-globin introns combined with the CMV promoter on recombinant expression levels in transient and stably recombinant CHO cells.

Adult stem cells balance self-renewal and differentiation to build, maintain and repair tissues. The role of signalling pathways and transcriptional networks in controlling stem cell function has been extensively studied, but there is increasing appreciation that mechanical forces also have a crucial regulatory role. Mechanical forces, signalling pathways and transcriptional networks must be coordinated across diverse length and timescales to maintain tissue homeostasis and function.
