Summary
Altered nuclear lamin expression is linked to cancer progression, but results vary. Understanding lamin functions in cancer cells is crucial for accurate diagnosis and treatment strategies.
Area of Science:
- Oncology
- Cell Biology
- Biochemistry
Background:
- Cancer diagnosis traditionally relies on nuclear shape abnormalities.
- Nuclear lamins, particularly lamins A and C, are implicated in nuclear architecture and cancer-related shape changes.
- Previous studies on lamin expression in various cancers have yielded inconsistent findings.
Purpose of the Study:
- To review existing literature on altered lamin expression in cancers.
- To explore the reasons for contradictory findings in previous studies.
- To emphasize the importance of considering lamin functions within the context of transformed cells.
Main Methods:
- Literature review of studies investigating lamin expression in cancer.
- Analysis of findings related to nuclear lamins A and C.
- Synthesis of information regarding epigenetic control and cellular functions.
Main Results:
- Expression patterns of nuclear lamins in cancer are complex and context-dependent.
- Contradictory results may stem from the heterogeneity of cancer and the need for a holistic approach.
- Altered epigenetic control alone does not fully explain lamin expression changes.
Conclusions:
- Individual lamin expression changes should not be analyzed in isolation.
- Understanding the functional roles of lamins in transformed cells is essential for cancer research.
- A comprehensive approach is needed to reconcile disparate findings and advance cancer diagnostics.

3.4K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

03:03mTOR Signaling and Cancer Progression
3.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

4.3K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

02:39lncRNA - Long Non-coding RNAs
7.5K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
